Product Highlights

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

Applications

Silane USi-2301 is an essential ingredient in many industries. Examples are :

  • Glass fiber or glass fabric composites : As a finish or a size ingredient
  • Foundry resins : As an additive to polyurethane resin
  • Sealants and adhesives : As a primer or additive
  • Mineral-filled polymers (composites) : For pretreatment of fillers and pigments or as an additive to the polymer
  • Paints and coatings : As an additive and primer for improving adhesion to the substrate, especially glass and metal
  • Improved shelf life over amino silanes in polyurethanes
