The silane coupling agent can chemically improve the combination of the organic resin and fillers/pigments, improve the crosslinking density and cohesive strength of the resin through the hydrolysis of alkoxy group and the reaction of the organic group with the resin.

It can also improve the adhesion strength between the resin and the substrate, can increase the water resistance of the system.

HENGDA Chemical is the first company in China to jointly develop polyether MS adhesives with adhesive manufacturers. Subsequently, we jointly developed silicone adhesive (structural adhesive and sealant) and silane-terminated polyurethane adhesive (adhesive and sealant) with adhesive manufacturers.
