Properties

The use of Silane OSi HIOSil GLYMO as a coupling agent In mineral-filled plastics improves filler

dispersibility, 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, Silane OSi HIOSil GLYMO improves both adhesion to the substrate and mechanical properties such as flexural strength, tensile strength and modulus of elasticity.
