Description

Silicic Acid Ethyltrishexadecyl Ester is a high-purity organosilicon compound, specifically a trialkylsilyl ester derivative. This specialty chemical serves as a versatile intermediate and functional additive, valued for its ability to impart hydrophobicity, modify surface properties, and enhance compatibility in complex formulations. It is essential for manufacturers in the personal care, coatings, plastics, and specialty lubricants industries seeking to improve product performance and stability.

Application

• Personal Care & Cosmetics: Acts as a hydrophobic agent and emollient in sunscreens, creams, and lotions to improve water resistance and skin feel.
• Coatings & Inks: Used as a flow control additive and surface modifier to enhance slip, mar resistance, and water repellency in industrial and protective coatings.
• Polymer & Plastic Additives: Functions as an internal lubricant and processing aid to improve mold release and reduce friction in engineering plastics and elastomers.
• Specialty Lubricants & Greases: Imparts thermal stability and water resistance when used as a thickening agent or performance additive in high-value lubricant formulations.
• Adhesives & Sealants: Enhances adhesion to low-energy surfaces and provides moisture resistance in silicone-modified and hybrid polymer systems.
• Textile & Leather Treatment: Serves as a durable water repellent (DWR) finishing agent for fabrics, fibers, and leather goods.
