Introduction:
3-(2,3-Epoxypropoxypropyl)trimethoxysilane is an epoxy functional silane, it is a clear, light liquid.
3-(2,3-Epoxypropoxypropyl)trimethoxysilane 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 water borne systems, e.g. improving the adhesion of acrylic latex sealants.
Typical Physical Properties:
Molecular Formula: C9H20O5Si
Molecular Weight: 236.4
Appearance: Colorless transparent liquid
Density: 1.065-1.075

Note:
3-(2,3-Epoxypropoxypropyl)trimethoxysilane reacts with water. Take precautions to avoid contact with atmospheric moisture.
Applications:
1.Improves dry and wet strength in cured composites reinforced with glass fiber rovings.
2.Enhances wet electrical properties of epoxy-based encapsulate and packaging materials.
3.Eliminates the need for a separate primer in polysulfide and urethane sealants.
4.Improves adhesion in waterborne acrylic sealants and in urethane and epoxy coatings.
Packing: 20kg or 200kg PVF steel drum or plastic drum
