Properties

The use of USi-2301 as a coupling agentIn 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,

USi-2301 improves both adhesion to thesubstrate and mechanical properties such as flexural strength, tensile strength and modulus of elasticity.
