Three major applications of silane coupling agents

The three major applications of silane coupling agents:

1. Surface treatment:It can improve the bonding performance between glass fiber and resin, enhance the strength, electrical, water resistance, weather resistance and other properties of glass fiber reinforced composite materials. Even in wet conditions, its effect on improving the mechanical properties of composite materials is significant. The use of silane coupling agents in glass fibers is quite common, accounting for about 50% of their total consumption. Among them, the most commonly used varieties are vinylsilane, aminosilane, methacryloyloxysilane, etc.

2. Used for filling plastic:The filler can be surface treated in advance or directly added to the resin, which can improve the dispersion and adhesion of the filler in the resin, enhance the compatibility between inorganic fillers and resin, improve process performance, and enhance the mechanical, electrical, and weather resistance properties of the filled plastic.

3. Used for sealing,Adhesive and coating thickening agents: can improve their adhesive strength, water resistance, weather resistance, and other properties. Silane coupling agents can often solve the problem of some materials being unable to bond for a long time. The principle of silane coupling agent as a viscosity enhancer is that it has two types of functional groups; A functional group can bond with the adhered skeleton material. And another type of functional group can bind with polymer materials or adhesives, forming strong chemical bonds at the bonding interface, greatly improving the bonding strength.
