Properties

Silane USi-3301, as a coupling agent inglass fiber-reinforced or filler-modified plastics improves filler dispersibility while reducing the filler's sedimentation tendency.

It is also a major reduction in the melt viscosity of casting resins, as well as a marked improvement in the mechanical properties of glass-fiber-reinforced or mineral-filled plastics.

In addition, it leads to a sizable increase in moisture resistance and greater resistance to acids and bases. Used as a co-monomer in polymers, silane USi-3301 produces binders that exhibit much improved wet scrub, abrasion and scratch resistance.

As a component of free-radical curable adhesives and sealants.
