Application

The introduction of long chain alkyl modified groups into silicone molecules can give silicone products new characteristics. As a new type of organosilane coupling agent, long chain alkyl trimethoxysilane can be used to treat inorganic materials (such as glass, SiO2, Al2O3, kaolin, mica, SiC, talc, etc.) to improve the compatibility of inorganic materials and organic materials (such as plastics, rubber, oil, adhesives) and enhance the mechanical properties of products. It is used as a glass anti-fogging agent, which can protect blank glass and film treatment glass (optical anti-reflection film, vacuum anti-reflection film, reflection film), and protect optical parts and precision instruments with scales and metal frames; It can be used as a cultural relic protection agent to prevent the destruction of cultural relics by acid corrosion and freeze-thaw weathering. Used as fabric finishing agent, it can make cotton, linen, wool and blended fabrics full (with thickening effect), smooth, wool feeling strong, and can effectively enhance the hydrophobicity of fabrics; It can also be used for modification of engineering plastics, waterproof and anticorrosion of buildings, and demoulding of rubber plastics.

It can also be used for surface modification of ultrafine powders, such as stationary phase surface treatment of chromatographic columns or separated materials.
