Midland, Michigan -- Dow Corning has introduced a new grade of silane coupling agent, that it says, "provides improved dispersion of mineral fillers in EPDM rubbers and thermoplastic resins. It increases initial and wet strengths of glass-filled polyester and other resin systems and can optimize electrical and physical properties of mineral-filled elastomers and plastics."
The new grade is called Z-6172 Silane, a Vinyl-tris-(2-methoxyethoxy) silane coupling agent, and according to the manufacturer, "is reactive in both free radical and hydrosilation chemistry, and has an organic reactive vinyl group and inorganic reactive methoxyethoxysilyl groups. The alkoxysilyl groups react to form siloxane bonds both to inorganic surfaces and materials, and also to other silane molecules to form a crosslinked network. The vinyl group participates in the peroxide cure chemistry of the resin or elastomer system."
