GENIOSIL® GF 92

GENIOSIL® GF 92 by Wacker is N-cyclohexyl-3-aminopropyltrimethoxysilane-based adhesion promoter. It binds via its aminoalkyl group to electrophilic groups in resins and polymers. Aside from groups such as epoxides and esters, it is particularly the isocyanate groups present in polyurethanes. Due to the nature of the amino group, this substance reacts as a strong base. The silane hydrolyzes autocatalytically in the presence of moisture (methanol is released) to form silanols, which can subsequently react with themselves to produce siloxanes or can bind to inorganic substrates. GENIOSIL® GF 92 is recommended for use in coatings.
