Description and features
The use of Silqon Glymo (3-glycidoxypropyltrimethoxysilane) as a coupling agent in mineral-filled plastics improves filler dispensability, reduces its sedimentation tendency and greatly lowers the resin’s viscosity. In addition it leads to higher filler loading and a marked increase in water (vapor) resistance as well as resistance to acids and bases. As a component of adhesives and sealants. Silqon A187 improves both adhesion to the substrate and mechanical properties such as flexural strength, tensile strength and modulus of elasticity.
