Gamma-Glycidoxypropyltrimethoxysilane

The Gamma-Glycidoxypropyltrimethoxysilane is an epoxy-functional silane; it is a clear, light straw liquid. It may 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.

Applications

The Gamma-Glycidoxypropyltrimethoxysilane may improve dry and wet strength in cured composites reinforced with glass fiber rovings.

It may enhance wet electrical properties of epoxy-based encapsulate and packaging materials.

The Gamma-Glycidoxypropyltrimethoxysilane may eliminate the need for a separate primer in polysulfide and urethane sealants.

It may improve adhesion in waterborne acrylic sealants and in urethane and epoxy coatings.
