Wacker Silane GF 91 Aminoalkyl methoxysilane Wacker Adhesion Promoters >> Organofunctional silane Acrylics/ Acrylates Aminoplaste & Phenoplastes (UF, MUF...) Polyesters Polyolefins (PE, PP…) SEALANT WACKER SILANE GF 91 Aminoalkyl methoxysilane. Applications: Filler treatment, Adhesion promotion at inorganic/organic interfaces, Hydrophilic modification of polysiloxanes. WACKER SILANE GF 91 is a chlorine-free aminoalkyl trimethoxysilane with a primary and a secondary amino function. It is especially suitable for improving adhesion at inorganic and organic interfaces, e.g. in glass-fiber composites or thermoset laminates. The use of WACKER SILANE GF 91 creates an excellent improvement of e.g. the mechanical properties, especially as an adhesion promoter in phenol, furan, urea or melamine resin formulations as well as in polyesters, polyolefins, acrylates or polycarbonates. In general WACKER SILANE GF 91 has a higher efficiency than monoamino silane esters. Chlorine-free aminoalkyl trimethoxysilane with a primary and a secondary amino function. Used for filler treatment, as an adhesion promoter at inorganic and organic interfaces such as glass-fiber composites or thermoset laminates, and for hydrophilic modification of polysiloxanes. Improves mechanical properties in phenol, furan, urea and melamine resin formulations, polyesters, polyolefins, acrylates and polycarbonates. Offers high efficiency.
