Properties

The use of Silane USi-2302 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 resistance, as well as resistance to acids and bases. As a component of adhesives and sealants

Silane USi-2302 improves both adhesion to The substrate and mechanical properties such as flexural strength, tensile strength and modulus of elasticity. In potting compounds for electronic components, it has a positive influence on properties such as volume resistivity and dielectric constant.
