3-Glycidoxypropyltrimethoxysilane

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.Applications:3-Glycidoxypropyltrimethoxysilane may improve dry and wet strength in cured composites reinforced with glass fiber rovingsEnhance wet electrical properties of epoxy-based encapsulate and packaging materials.Eliminate the need for a separate primer in polysulfide and urethane sealants.Improve adhesion in waterborne acrylic sealants and in urethane and epoxy coatings.
Colorless transparent liquid;Soluble in a variety of organic solvents;Easy to hydrolysis;Able for condensation to form polysiloxanes;Easy to polymerize in the presence of overheating, light and peroxide.
