Product number PR-560
Chemical Name (3-Glycidoxypropyl)trimethoxysilane
English name 3-glycidoxypropyltrimethoxysilane
Chemical structural formula 3-Glycidoxypropyltrimethoxysilane is an epoxy-functional silane, it is a clear, light straw liquid. 3-Glycidoxypropyltrimethoxysilane may be used as a coupling agent in polysulfide and polyurethane caulks and sealants, in mineral-filled or glass-reinforced thermosets and thermoplastics, and in glass roving size-binders. It is particularly employed as an adhesion-promoting additive in waterborne systems, e.g. improving the adhesion of acrylic latex sealants.
