Properties

Silane AC-240, as a coupling agent in glass 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 AC-240 produces binders that exhibit much improved wet scrub, abrasion and scratch resistance. As a component of free   -radical curable adhesives and sealants.

Applications

Silane AC-240 is used as adhesion promoter in application such as :

A constituent of glass fiber size (glass fiber fillers for unsaturated polyester resins and polyolefins)

A finish for glass fabrics used in unsaturated polyester resins

As a surface modifier for pigments and fillers for thermosets (unsaturated polyester, MMA), thermoplastics (polyesters and polyolefins) and elastomers

As an additive for filled, peroxide-crosslinked elastomers

As an additive for casting resins (unsaturated polyester, MMA)
