Properties

AC-D211, as an adhesion promoter in glassfiber reinforced or filler modified plastics increases filler dispersibility and improves numerous mechanical properties of the composites. Additionally, it reduce the fillers' sedimentation tendency in the uncured polymer. AC-D211 also can improve resistance to water and corrosion. meanwhile, the mechanical properties can be adjusted with even greater precision by means of the dialkoxysilyl group. As textile finishing agents, silicones modified with AC-D211 result in amino modified silicone fluids that are an ideal active ingredient in softener formulations for finishing fibers and textiles.

Applications

When used as an additive, Silane AC-220i meets the need of special primers in numerous bonding applications. Also can display a good adhesion in the followingsystems:

RTV silicones and hybrid silane-crosslinked sealants:  improve the adhesion single & double component silicone-crosslinked sealants to a variety of substrates

Polysulfide sealants:  better adhesion to glass, aluminum and steel

Plastic sealants:  improve bonding to metal substrates and better performance

Additive in phenolic and epoxy molding compounds: improve wet electrical properties
