Silane KH-1524 is widely used in the following areas:

① Metal preservatives

The silane has a sulfhydryl group and has a special effect as a metal surface antirust agent. It can be used to deal with metal surface such as gold, silver and copper to improve its corrosion resistance, antioxidation and improve the adhesion to polymer materials.

② Polymer filled materials

This product is widely used in filled polymer materials. It can be applied to thermosetting and thermoplastic polymer materials, such as epoxy, finishing, phenolic sulfonyl, polystyrene, polystyrene, inkstone and so on. Especially in the rubber industry, it can improve its mechanical properties, improve its wear resistance and reduce permanent deformation. It is suitable for NR, EPDM, SBR, polysulfide rubber, styrene butadiene rubber, NBR, neoprene and polyurethane rubber. It has a wide range of inorganic filler, which can be used in glass fiber, silica, quartz powder, talcum, mica, fly ash clay, clay, and so on.

③ Reinforcing agent and crosslinking promoter

As a reinforcing agent and crosslinking promoter, this product is widely used in composite materials, paints, coatings, ink, adhesives and sealing materials to provide adhesive strength and to improve the water resistance of products.

④ Casting resin

This product can improve the bonding strength and molding sand strength of the casting resin of the cold box. It can reduce the amount of resin and gas, improve the quality of the casting and reduce the waste rate on the premise of maintaining the strength of the molding sand.

⑤ Synthetic resin materials

The synthetic resin can effectively improve the moisture resistance and temperature resistance of the synthetic resin.
