The use of AC-310 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,

AC-310 improves both adhesion to the substrate and mechanical properties such as flexural strength, tensile strength and modulus of elasticity.



Silane AC-310 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
