Dow Corning Z-6032 Silane vinylbenzylamine functional silane Dow Corning Adhesion promoter / Bonding agent Alkyd Resins Epoxy Resins Vinyl Methanol Silane is used primarily as a coupling agent to improve adhesion of free radical cured resins, such as polyester, to inorganic surfaces including fiberglass, clay, quartz and other siliceous materials. Recommended usage level: Primer: dilute to 0.1-0.5% in acidified (pH=4.0) water; Additive: 0.5-3.0 wt% organofunctional silane that improves chemical bonding; good resin wet-out; increases flexural and tensile strengths. Coupling agent to improve adhesion of organic resins to inorganic surfaces. Recommended usage level: 0.05-2.0 wt% based on solids. Typically added during the let-down.
