Application: 
Because of its special properties, it is widely used in fiberglass reinforced plastics, coatings, foundry, plastics, adhesives, sealants, textile printing and dyeing and other industries. In the field of glass fiber, this product is an excellent treatment agent, which can greatly improve the mechanical strength, electrical properties and anti-aging properties of various resin, nylon, polysulfone and other FRP materials, making this FRP widely used in the manufacture of mechanical parts, building materials, pressure containers and materials for special purposes. For cold-hardened resin sand in foundry industry, this product is the best coupling agent in domestic silane. As long as a small amount of silane is added to the resin, the strength of furan sand can be increased after dissolving by itself, which greatly reduces the amount of resin added and consequently reduces the cost. Therefore, adding this product is a very beneficial measure in the foundry industry. In adhesives, this product can play a role as an accelerator, thereby significantly improving the bonding strength between the adhesives and the adhesives. In the rubber industry, this product can play the role of rubber and metal bonding tackifier. It is suitable for epoxy resin, phenolic resin, polyurethane, chloroprene rubber, nitrile rubber and other adhesives and sealants. It can also be used as a coupling agent for inorganic filled composite polymer materials, which can improve the mechanical strength, aging resistance and electrical properties of products. The suitable inorganic fillers are glass fiber, glass cloth, glass beads, silica, talc powder, mica powder, kaolin, etc. It is also used as a coupling agent for coatings, other adhesives and sand mould reinforcers.
