The quality Fluorosilane coupling agent is also called vinylsilane, aminosilane, epoxysilane, mercaptosilane and methacryloxysilane, etc. These kinds of organofunctional silanes are commonly used quality Fluorosilane coupling agents. Its application can be roughly classified into three aspects:
1. For the surface treatment of glass fiber, it can improve the bonding properties of glass fiber and resin, and greatly improve the strength, electrical, water resistance, weather resistance and other properties of glass fiber reinforced composite materials. The improvement of the mechanical properties of the material is also very effective.
At present, the use of quality Fluorosilane coupling agent in glass fibers is quite common. The quality Fluorosilane coupling agent used in this aspect accounts for about 50% of its total consumption. Among them, the most used varieties are vinylsilane, aminosilane, Methacryloxysilane, etc.
2. Used to fill plastics with inorganic fillers. The filler can be surface-treated in advance or directly added to the resin. It can improve the dispersion and adhesion of fillers in resins, improve process performance and improve the mechanical, electrical and weather resistance properties of filled plastics.
3. It is used as a tackifier for sealants, adhesives and coatings, which can improve their bonding strength, water resistance, weather resistance and other properties. The quality Fluorosilane coupling agent can often solve the problem that some materials cannot be bonded for a long time.
