Potassium Methyl Silicate Potassium methyl silicate is primarily an alkaline aqueous solution of potassium and methylamine. It reacts with CO₂ or other acidic compounds in the air to form the active substance polymethylsilicic acid, which imparts waterproof properties. It is primarily used in mineral water repellents. This product must be diluted with water before use. It waterproofs surfaces and reduces water absorption. It is permeable and absorbent, while maintaining the natural appearance of the substrate. It reacts with CO₂ or other acidic compounds in the air to form an insoluble, waterproof, breathable, and resilient membrane on the surface of the substrate. This membrane offers excellent waterproofing, anti-seepage, moisture-proofing, rust-resistance, anti-aging, and anti-fouling properties. It prevents water absorption into the substrate, thereby reducing flaking caused by freeze-thaw and weathering, and extending the life of the substrate. This product is simple to apply, low-cost, and offers long-lasting results. It is washable and resistant to high and low temperatures (-50°C to 150°C).      

How to Use Silicone Solid Powder Waterproofing Agent As a key material in building waterproofing, silicone solid powder waterproofing agent's application process embodies rigorous scientific principles and practical wisdom. This white powder forms a permanent waterproof layer within the substrate through an activation reaction. Its application method must adhere to the objective laws of chemical reactions while also taking into account the actual conditions of on-site construction. The application of silicone solid powder waterproofing agent begins with substrate pretreatment. Before application, ensure that the concrete or mortar base has reached a 28-day curing age, a surface strength of at least C20, and a moisture content of less than 8%. Substrates with oil or laitance should be mechanically polished and vacuumed to fully expose the capillary pores. Actual data from a project shows that sandblasting can increase the penetration depth of substrates by 40% compared to conventional cleaning. The material preparation process reflects the precise control of chemical reactions. It is recommended to mix the slurry at a mass ratio of 1:0.3-0.35 using an electric mixer at 300 rpm or higher, continuously mixing for 3 minutes until a paste forms. Temperature is crucial; when the ambient temperature is below 5°C, a catalyst (2% by weight) should be added. Laboratory studies have confirmed that the slurry should be applied within 45 minutes after mixing at 20°C. Exceeding this time limit will cause a 60% decrease in fluidity due to silanol group condensation. The application process determines the ultimate effectiveness of the waterproofing layer. When applying the first coat with a stiff brush, apply a standard amount of 0.8 kg/m² in a cross-coat pattern, focusing on corners and pipe bases. Apply a second coat after a 4-hour interval, reducing the amount to 0.3 kg/m². For vertical surfaces, it is recommended to add 3% of a thixotropic agent to prevent sagging. In a high-speed railway tunnel project, concrete test blocks that had undergone two coats of the slurry exhibited a water seepage depth of no more than 3 mm under a water pressure of 0.8 MPa for 72 hours. The curing phase directly impacts the quality of crystal development. For 24 hours after application, avoid rain erosion, cover with plastic sheeting, and maintain an ambient humidity of ≥70%. Under standard curing conditions at 25°C, a complete hydrophobic network will form after 7 days, with a contact angle test result exceeding 120°. Steam curing can be used to accelerate the reaction in special circumstances, but the temperature must not exceed 60°C to avoid siloxane chain breakage. After 28 days of complete curing, the waterproofing layer is resistant to chemical attack at pH values ​​of 3 to 11 and has a service life of over 15 years. The application technology system for organosilicon solid powder waterproofing agents forms a closed-loop management system, from substrate preparation to final curing. This material retains the penetrating and crystallizing properties of traditional waterproofing agents while eliminating the transportation and storage challenges of liquid products through its solid powder form. Mastering its scientific application method can provide more reliable technical support for building waterproofing projects, especially in long-term submerged environments such as basements and pools. Actual application should be considered in light of the specific project characteristics, and sample area testing should be conducted as necessary to optimize parameters.

Application of Amino-terminated Polydimethylsiloxane in Various Industries Bis(3-aminopropyl)-terminated polydimethylsiloxane is an amino-terminated silicone oil. Thanks to its polydimethylsiloxane backbone, it inherits the low surface energy, high and low temperature resistance, and outstanding flexibility of silicone materials. Furthermore, the aminopropyl functional groups at both ends of the molecule possess the high reactivity and functionalization potential of amino groups, making it an in-demand material in many fields: 01 Polymer Material Modification: A "Performance Amplifier" for Engineering Materials Amino groups can react with epoxy groups, isocyanate groups, aldehydes, and ketones, providing a key approach for customized modification of materials such as polyimides, polyamides, polyurethanes, and epoxy resins. These modified materials combine the advantages of silicone, such as low surface energy, high and low temperature resistance, and aging resistance, with the inherent strength and rigidity of the substrate.   02 Personal Care: An "Invisible Hair Care" Amino-terminated silicone oil is a key additive in personal care products such as shampoos, conditioners, and hair treatments. Because terminal amino silicone oil has strong adsorption and a long siloxane molecular chain segment, it can react with the hydroxyl and carboxyl groups on the hair surface [1], forming a smooth protective film on the hair surface, smoothing frizzy and split ends, giving the hair a moisturized, smooth and flowing feeling, improving the dry and wet combing properties of the hair, and deeply repairing damaged hair.   03 Textile Industry: The "Soft Magician" of Fabric Softening The demand for "soft, skin-friendly and washable" textile fabrics can be precisely met by terminal amino silicone oil. The high reactivity of amino groups can efficiently combine with the fiber surface, allowing the siloxane chain segments to be directional adsorbed on the fiber surface, reducing the friction coefficient between fibers, giving the fabric a soft, smooth and plump feel, and providing good washability and breathability.   Manta F10 Series Terminal Amino Silicone Oil Manta uses its own core intermediate, amino capping agent, as a key support, controlling the quality of raw materials from the source and ensuring the controllability of the supply chain. It has launched terminal amino silicone oil covering multiple application scenarios, accurately matching the differentiated needs of customers in different industries.   About Nanjing Manta Manta is a high-tech enterprise specializing in the research, development, production, and sales of functional silicone materials, MS polymers, additives, and specialized new silicone materials.

We should first understand the characteristics of the product. For example, one-component silicone sealant is a paste made of polydimethylsiloxane as the main raw material, supplemented by crosslinking agent, filler, plasticizer, coupling agent, and catalyst mixed in a vacuum state. It solidifies at room temperature by reacting with water in the air to form elastic silicone rubber.   One-component silanized polyurethane sealant is a chemical term with the property of silanized polyurethane. The main raw materials are polyether polyols, pure MDI, TDI and IPDI, Silane AMEO, Nanda-42 silane coupling agent, calcium carbonate, fumed silica, stannous octoate, and dibutyl phthalate.   MS polymer is a cross-linked polymer based on silane-terminated polyether. MS polymer-based products do not contain silicone components and solvents, nor do they contain polyurethane groups. Most formulations are odorless and environmentally friendly. The inherent elasticity of MS adhesives and sealants can absorb and compensate for dynamic loads, evenly transfer forces, and prevent premature fatigue of materials. MS-based materials can achieve bonding between a variety of substrates.   Therefore, modified silicone sealants and modified silane sealants can be said to be almost the same type of products, but different manufacturers have differences in formula and quality, and the products produced will also have performance differences. It can be understood that they are just different names. Both are MS (Modify Silicon: modified silane or modified silicone) glue. The typical feature of MS glue is that it does not require surface treatment, such as primers, and MS polymers are cross-linked or cured by continuous exposure to moisture. Moisture mainly comes from the air or the bonded substrate itself. SPUR is the abbreviation of silane-terminated polyurethane similar to MS polymers, and STP is a silane-terminated polyether (STP) containing polyurethane groups similar to MS polymers. In essence, MS, SPUR and STP are three different polymers.   MS modified silane sealant is a silicon-substituted analogue of carbon alkane with the addition of MS prepolymer, plasticizer, thixotropic agent and other fillers. The toxicity of silane is eliminated through modification. MS sealant is also called silane modified polyether sealant. Since it does not contain formaldehyde or isocyanate, it has outstanding environmental protection characteristics such as solvent-free, non-toxic and odorless, and low VOC release. It is friendly to the environment and human body; it is suitable for most building substrates, has good construction performance, adhesion, durability and weather resistance, and is especially non-polluting.

1. Polymethylsilsesquioxane (commonly known as P.P powder) A typical silicone resin that can be dissolved in a variety of cosmetic oils and forms a thin film on the skin surface. This ingredient is the first magical thing in cosmetics to be discussed today. This ingredient is widely used in lipstick, primer, foundation, sunscreen and other cosmetics. It is a typical opaque emollient.   It is flexible and fits the skin, improving the waterproof and oil-proof properties of cosmetics; it has the effect of softening the skin, providing extra fat to the skin, reducing the evaporation of skin moisture, rehydrating dry skin and hardened stratum corneum, and restoring luster, softness and elasticity; adding polymethylsilsesquioxane to makeup can alleviate the problem of makeup smudge and reduce the phenomenon of color migration. The spherical polymethylsilsesquioxane silicon powder has a particle size of 15 microns. The PP powder is made by special process technology. The powdered silicone resin has infusible thermosetting properties. It combines the advantages of inorganic powder and organic powder. It has a smooth and silky skin feel and excellent water resistance. PP powder has excellent stability, safety and compatibility. It also has a velvety smoothness and touch. It has a high performance-price ratio and is an excellent substitute for nylon powder, spherical silica powder and boron nitride powder.   *Silky and powdery skin feel: PP powder combines the advantages of inorganic powder and organic powder. It is different from the cold hardness of inorganic mineral powder. Its silicone properties make it It feels soft and elastic when touched, as smooth as silk. * Anti-caking: Many dry powder formulas have the problem of caking or not flowing freely after storage. This situation is generally caused by moisture absorption. PP powder has water resistance, which helps prevent loose powder from agglomerating. * Matte oil control effect: The spherical surface of PP powder has a scattering effect on light. After absorbing oil, it shows a transparent matte effect. Combined with other silicone raw materials, it can create a unique and long-lasting matte oil control system, which can cover fine wrinkles, block ultraviolet rays and protect the skin. * Promote pigment dispersion: Because PP powder has the characteristics of both inorganic materials, it can act as a medium between the two. Especially in oil-containing cosmetics, both organic and inorganic pigments can be evenly dispersed in the system through the transportation of PP powder. It can not only save the amount of pigment, but also improve the vividness of the color. The recommended dosage in cosmetics is 05%~25%, and the recommended dosage in sunscreen and skin care products is 1%~5%.   2. Mineral oil A highly pure and lightweight ingredient used in baby lotions, cold creams, ointments and many other cosmetic and personal care products, it helps reduce skin moisture loss and keeps it moisturized.   Mineral oil is a grease extracted from petroleum, colorless, odorless and hypoallergenic. It has antistatic effects and is used as a solvent and emollient in cosmetics. Mineral oil is divided into cosmetic grade and medicinal grade. Cosmetic grade mineral oil is highly safe, less irritating, and can also achieve antioxidant effects. However, mineral oil with low purity may cause skin irritation due to the presence of aromatic components. It should be avoided for sensitive skin and may also cause acne. The higher the purity of the mineral oil, the safer it is for the skin. The highly refined, purified mineral oil used in cosmetics and skin care products is non-comedogenic. It is an inert and stable compound. Mineral oil is used in many products for sensitive skin, and is relatively less likely to cause skin reactions and will not deteriorate in humid climates. Paula Ingredient Lyrics and Songs in the United States believes that cosmetic grade mineral oil and Vaseline are considered to be the safest and least allergenic moisturizing ingredients to date. The mineral oil in skin care products is certified by USP (United States Pharmacopoeia) or BP (British Pharmacopoeia), which is completely safe, soothing and sensitizing.   3. Hydrogenated polyisobutene A synthetic oil, similar to the properties of natural squalane, good breathability and non-greasy. As an emollient, it provides oil to the skin, prevents water evaporation, restores softness and elasticity to dry skin or hardened stratum corneum, and provides a light silky skin feel to the skin. As a film-forming agent, it covers the surface of the skin or hair to form a continuous film, locks in moisture, and makes the skin and hair soft, similar to the effect of skin emollients; as a viscosity controller, it can increase the viscosity of the product and stabilize the product state. Hydrogenated polyisobutene is a synthetic polymer, mainly used as a film-forming emollient and viscosity controller in cosmetics. Hydrogenated polyisobutene has the cosmetic properties of squalane, so it is called synthetic squalane. At present, the hydrogenated polyisobutylene used in my country mainly comes from Nippon Oil & Fats Co., Ltd., with the trade name Polysynlane. It is an isomeric straight-chain alkane that can be used in cosmetics and medicines. It has the functions of moisturizing, hydrating and lubricating. It has similar properties to natural squalane, but is much cheaper. It is mainly used in cosmetics such as lipsticks and creams.

D5 is the abbreviation of decamethylcyclopentasiloxane, and its INCI name is Cyclopentasiloxane. It is a kind of synthetic silicone oil and is widely used in cosmetics and body care products. This ingredient is colorless and odorless, refreshing and non-greasy, has certain volatility, is easy to spread, can produce a lubricating and silky feeling, and has certain conditioning properties. At the same time, it has good compatibility with other cosmetic raw materials.   However, since this ingredient is very difficult to degrade and has bioaccumulation in organisms, it will have potential impacts on the environment. It has been officially listed as a restricted substance by the EU. Since the first proposal in 2015, the UK has submitted a proposal to the European Chemicals Agency (ECA) on "limiting the use of D4 and Cyclopentasiloxane in cosmetics that can be washed off under normal use conditions." By 2018, the EU issued a revision of Annex XV of REACH Regulation (EC) No1907/2006: After January 31, 2020, the concentration of D4/Cyclopentasiloxane in wash-off cosmetics should be less than 0.1%.   To solve this problem, we need to find a substitute that is close to the important properties of Cyclopentasiloxane. Our company recommends our volatile silicone oils: linear and branched volatile silicone oils, which evaporate quickly, feel refreshing, have low surface tension, and good compatibility. Based on EU regulations and market demand, Manta has proposed 3 alternatives for Cyclopentasiloxane to meet the needs of different customers.   D5 solution recommendation: Product Code INCI NAME Viscosity/cs Designed Production Capacity Manta F1006(1.5cSt) Dimethicone 1.5 2000t/a Manta F1006(2cSt) Dimethicone 2 3000t/a Manta F1043 Methyl trimethicone 1.5 1000t/a   The low-ring silicone oil products for cosmetics developed by Manta Silicone are greener and more environmentally friendly than Cyclopentasiloxane, and have unique volatility. They feel refreshing and non-sticky on the skin. They can meet the needs of various formulas such as skin care, makeup, and sunscreen, and are an excellent substitute for D5.          

The raw materials of cosmetic powder can be roughly divided into four categories, ①Coloring pigments for adjusting color (such as iron red and iron yellow); ②White powders for covering, whitening and blocking ultraviolet rays (such as titanium dioxide and zinc oxide); ③Pearlescent pigments for improving gloss (composed of mica coated with several metal oxide thin layers. Changing the metal oxide thin layers can produce different pearlescent effects); ④Physical powders for adjusting product spreadability, adsorption, skin adhesion and texture (such as talcum powder, starch, polymethyl methacrylate).   Today we will introduce the fourth type - body powder, which can also be said to be a skin feel regulator. It includes three categories: inorganic powder, organic powder and natural powder: ① Inorganic powder, commonly used are silicon dioxide, talc, mica; ② Organic powder, commonly used are polymethyl methacrylate, polymethyl silsesquioxane, vinyl polydimethylsiloxane/polymethylsiloxane silsesquioxane cross-linked polymer, nylon powder, polyurethane powder; ③ Natural powder, commonly used are corn starch, cassava starch, modified starch, etc.   1. Inorganic powder   1). Silicon dioxide (silica) Silica is also called silica. There are two types of crystalline silicon dioxide and amorphous silicon dioxide in nature. Crystalline silicon dioxide is divided into three types: quartz, tridymite and cristobalite due to different crystal structures. Pure quartz is a colorless crystal. Large and transparent prismatic quartz is called crystal. If the crystal contains trace impurities, it has different colors, such as amethyst, tea crystal, black crystal, etc.   Silica for cosmetics is colorless, transparent, shiny crystals and amorphous powders. It has high hardness, is odorless, chemically inert, insoluble in water and acid (except hydrofluoric acid), soluble in concentrated alkali solution, very stable within the pH range of cosmetics, and has good lubricity and oil absorption.   2). Mica Mica is a general term for mica minerals. It is an aluminum silicate of metals such as potassium, aluminum, magnesium, iron, and lithium. It is a layered structure, monoclinic system, and the crystals are pseudo-hexagonal flakes or plates, occasionally columnar. The mica powder used in cosmetics is mainly muscovite and sericite. Muscovite is soft and shiny, and sericite is soft and smooth to the touch. The particles will not agglomerate. Because it is a very thin flaky crystal (0.2~0.5 μm), it is almost transparent when applied to the skin and will not turn white. Due to its molecular structure, mica has strong adhesion and moderate gloss and softness. After special processing, it can be made into synthetic mica, which improves the brightness and durability of makeup while improving whiteness.   2. Organic powder 1). Polymethyl methacrylate (PMMA) PMMA, also known as acrylic or organic glass, has a lower hardness than silica. It can adjust the fluidity of the product and improve the formability of the product. It has no covering power and a smooth skin feel. It has a lubricating effect in powder and scented powder, improves the dispersion of the pigment, avoids unevenness during use, forms a uniform lubricating film on the skin surface, and provides a soft powdery feel in base makeup and skin care products. 2). Polymethylsilsesquioxane (PMSQ) PMSQ is a spherical powder with a very uniform particle size distribution. The smaller the particle size, the more matte the makeup, and the larger the particle size, the smoother the skin feel. PMSQ has the stability of inorganic powder, and at the same time has excellent spreadability, smoothness and fluidity, and has good waterproofness and certain oil absorption performance. By increasing the light diffuse transmittance and changing the light path, it brings a soft focus effect to the skin, helps to cover wrinkles and blemishes, and creates a matte natural makeup.   3. Natural powder Natural raw materials generally have good safety and environmental friendliness, but have great limitations in application functions. Starch: There are more than 40 kinds of cosmetic raw materials related to starch in the "List of Used Cosmetic Raw Materials" (2015 edition), including modified starches such as hydroxypropyl starch, carboxymethyl starch, esterified starch and starch copolymers, as well as some special native starches such as oat starch and kudzu starch. Modified starch can be used as a matrix raw material for cosmetics to give the product suitable fluidity and dispersibility, and improve the stability and spreadability of the product; modified starch can also be used as a carrier for functional cosmetics to adsorb, embed and slowly release active ingredients, and improve the stability and effect of active ingredients; some modified starches have moisturizing and conditioning properties and can be directly used as functional ingredients in cosmetics.      

Improving product texture and feel The silky texture in luxury beauty products often comes from silicone ingredients such as polymethylsilsesquioxane. It helps to provide a smooth product texture that is easy to spread on the skin. Polymethylsilsesquioxane also has anti-caking properties that can be used in cosmetics. Film-forming Polymethylsilsesquioxane forms a film on the skin, providing a smooth, silky feel. This helps to lock moisture on the skin and provide water resistance. This is useful in the formulation of sunscreens and cosmetics such as eyeshadow. Oil absorption Polymethylsilsesquioxane absorbs sebum from the surface of the skin. This reduces the greasy feeling of oily skin. It also helps to limit the dreaded "shine" that can occur with oily skin later in the day. Improve skin tone, youthful complexion Silicones such as polymethylsilsesquioxane are popular in anti-aging products because they help the skin retain moisture for a smoother, plumper complexion. It can also reduce the appearance of fine lines and wrinkles. Polymethylsilsesquioxane can actually fill in fine lines, wrinkles, and uneven texture (temporarily) for a smoother, more youthful appearance. Polymethylsilsesquioxane is a silicone widely used in skin care, cosmetics, and personal care products. It provides a wrinkle-masking effect by smoothing fine lines, wrinkles, and blemishes. Silicone ingredients like polymethylsilsesquioxane are used in moisturizers, anti-aging creams, eyeshadows, shampoos, conditioners, and more.    

  Understanding Alpha Silane Modified Polymers (SMPs) Alpha silane modified polymers (SMPs) represent a significant advancement in materials science, offering a unique combination of properties and performance benefits. These polymers are created by incorporating silane groups onto the end of a polymer backbone, specifically using a unique "alpha" bonding configuration. This distinct structure imparts exceptional characteristics to the resulting material.
