Wacker Silane GF 31 Methacryloxyalkyl trimethoxysilane Wacker Adhesion Promoters >> Organofunctional silane Acrylics/ Acrylates Polyesters Polyolefins (PE, PP…) SEALANT WACKER SILANE GF 31 is a methacryloxyalkyl trimethoxysilane. It is highly suitable as a co-monomer for moisture-curing (meth)acrylic copolymers that cure via silanol groups. WACKER SILANE GF 31 is also recommended for use in treatment of fillers and as an adhesion promoter at inorganic/organic interfaces. In these applications WACKER SILAN GF 31 is especially suitable for improving the mechanical properties of acrylic and butyl polymers as well as for polyesters, polyethers and polyolefins.
