1. Used in the fiberglass industry.
The treatment and improvement of the surface of the glass fiber can improve the adhesion of the glass fiber and the resin, and greatly improve the strength, electrical, water resistance, weather resistance and the like of the glass fiber reinforced composite material, even in the wet state, it is compounded The mechanical properties of the material are improved and the effect is also remarkable. At present, the use of silane coupling agents in glass fibers has become quite common. The silane coupling agent used in this aspect accounts for about 50% of the total consumption, and the most used varieties are vinyl silane, amino silane, Methacryloxysilane or the like.

2. Used in the plastics and composite materials industry.
The inorganic filler may be surface-treated in advance or may be directly added to the resin. It can improve the dispersibility and adhesion of the filler in the resin, improve the process performance and improve the mechanical, electrical and weather resistance properties of the filled plastics (including rubber).

3, used in the rubber industry (silicone, epoxy, sealant), sealants, adhesives and other industries.
Can improve their bonding strength, water resistance, weather resistance and other properties. Silane coupling agents often solve the problem that certain materials have not been able to bond for a long time. The principle of the silane coupling agent acting as a tackifier is that it has two groups in itself, one group can be bonded to the bonded matrix material, and the other group can be combined with the polymer material or the binder. Thus, a strong chemical bond is formed at the bonding interface, which greatly improves the bonding strength. There are generally three methods for the application of the silane coupling agent: one is a surface treatment agent as a skeleton material; the other is added to the binder, and the third is directly added to the polymer material. The first two methods are better from the perspective of giving full play to their effectiveness and reducing costs.

4. Used in the foundry industry.
It can improve the surface properties of organic and inorganic materials and enhance the adhesion of fillers to resins. In particular, it is used in the foundry industry after mixing with furan resin, and its molding sand strength and resin storage period are significantly improved.

5. Used in the coatings industry.
Enhance the adhesion of air-drying coatings to difficult-to-attach substrates (especially epoxy, alkyd, polyurethane, acrylic, etc.), greatly improve their water resistance and salt spray resistance; used in epoxy heavy-duty anti-corrosion systems It can greatly improve its resistance to harsh environmental conditions, enhance the water repellency of the paint film, and improve the anti-corrosion performance of the paint.
