Chemical Structure
Introduction
PC3100 is an epoxy-functional silane, it is a clear, light straw liquid. PC3100 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.
