Introduction
It is an epoxy-functional silane, it is a clear, light straw liquid. 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
Improves dry and wet strength in cured composites reinforced with glass fiber rovings.
l Enhances wet electrical properties of epoxy-based encapsulate and packaging materials.
l Eliminates the need for a separate primer in polysulfide and urethane sealants.
l Improves adhesion in waterborne acrylic sealants and in urethane and epoxy coatings.
