Improved dispersion of mineral fillers in thermoplastics and EPDM rubbers is reportedly achieved with a new silane coupling agent from Dow Corning Corp., Midland, Mich. Z-6172 Silane reportedly increases initial and wet strengths of glass-filled polyester and other resins and optimizes electrical and physical properties of mineral-filled plastics and elastomers. It has two kinds of reactive groups: organic vinyl and inorganic methoxyethoxysilyl. Alkoxysilyl groups react to form siloxane bonds to inorganic surfaces and materials, and also to other silane molecules to form a crosslinked network. The vinyl group participates in the peroxide cure of the resin or elastomer system.
