Applications
This product is a difunctional coupling agent mainly used to improve the adhesion of organic materials to inorganic substrates, compatible with most organic and inorganic materials.
Raw material for diamino-modified silicone oil & silicone softeners
Amino groups grafted onto the silicone backbone greatly improve orientation and affinity on fibers, imparting super softness, smoothness, drape, antistatic property, washability and wrinkle resistance to various fibers.
Silane curing & polysulfide sealants
Used in one-/two-component crosslinkable silicone and polysulfide sealants to improve adhesion to substrates (cement, copper, glass, etc.). It enables bubble-free curing and gives a light-colored system.
