Uses
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 rovings
Enhance 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. Pre-treatment of carbon steel with 3-(Glycidoxypropyl)trimet?hoxysilane enhances the dry and wet adhesion while reducing the cathotic disbondment rate of an epoxy coating (3-Glycidoxypropyl)trimethoxysilane is used in the production of carbon steel and its pre treatment favors the dry and wet adhesion of epoxy coating. It is also used to prepare epoxy-functionalized silica nanoparticles, which gives a reactive surface for one-step and high-density protein immobilization. It serves as a coupling agent and adhesion promoter.
