Silane coupling agent for glass fiber surface treatment

As an inorganic non-metallic material, glass fiber has good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. It is often used as a reinforcing material in composite materials, electrical insulation material and thermal insulation material. However, the surface of glass fiber is very polar, and it is difficult to be compatible with non-polar resin, which greatly reduces its filling effect.

In order to improve the adhesion between resin and glass fiber and improve the strength, water resistance, electrical and weather resistance of glass fiber reinforced composites, it is necessary to modify the surface of glass fiber.

At present, the most commonly used surface modifier in the surface modification of glass fiber is silane coupling agent, and its varieties mainly include: vinyl silane, amino silane, methacryloxy silane, etc.
