Wacker Silane GF 93 Aminoalkyl ethoxysilane Wacker Adhesion Promoters >> Organofunctional silane Acrylics/ Acrylates Epoxy (EP) Aminoplaste & Phenoplastes (UF, MUF...) PU - Prepolymers SEALANT WACKER SILANE GF 93 Aminoalkyl ethoxysilane. Applications: Adhesion promotion between inorganic and organic materials, Filler treatment, Polymer modification. WACKER SILANE GF 93 is an aminoalkyl ethoxysilane. It is especially suitable for silyl modification of polyurethanes (PU) terminated with isocyanate groups. It makes a moisture curing of PU possible. WACKER SILANE GF 93 also has excellent properties especially as an adhesion promoter to improve the bonding of acrylic, epoxy or melamine resins to inorganic surfaces, e.g. for pretreatment of fillers for acrylic, melamine or epoxy resins. WACKER SILANE GF 93 is also used as a basis for primer solutions - suitable for unspecific interface problems as well. Aminoalkyl ethoxysilane. Used for silyl modification of polyurethanes terminated with isocyanate groups, as an adhesion promoter to improve the bonding of acrylic, epoxy or melamine resins to inorganic surfaces, and for pretreatment of fillers for acrylic, melamine or epoxy resins.
