Application Fields of Polyether-Modified Trisiloxane Personal Care Products Widely used in hair spray, leave-in hair care products, skin lotions, shaving creams, shampoos, etc. It can enhance hair smoothness and gloss, improve skin touch to make it smooth and delicate, and also serve as a silicone oil emulsifier^1,3,4. Pesticide Field Can be directly mixed with herbicides, insecticides, etc. It reduces the surface tension of pesticide solutions, improves the wetting, spreading, and penetration of pesticides on plant surfaces, enhances pesticide efficacy, and reduces pesticide usage^2,5,6. Coatings and Inks Industry Used as leveling agents, wetting agents, and defoamers. It improves the fluidity and leveling of coatings and inks, enhances coating quality and gloss, prevents defects such as craters and pinholes, and plays a role in defoaming and antifoaming to improve production efficiency and product quality⁵. Textile Industry Applied in fiber and fabric finishing. The introduction of polyether groups increases the hygroscopicity, antistatic property, and soil release property of finished fibers or fabrics, making them softer and smoother and improving their service performance^1,3. Leather Processing Used as a leather fatliquor, suitable for both water-based and solvent-based systems. It endows leather with good softness, fullness, and waterproof performance, while improving its wear resistance and tear strength². Building Materials Used as a defoamer in the production of cement mortar, concrete, etc. It effectively controls foam generation, makes concrete components denser and brighter, and improves the strength and durability of building materials.
