- Properties
In addition to its application as an adhesion promoter in formulations and primers, GENIOSIL® GF 93 functions as a surface modifier in fillers and pigments, where it improves the dispersibility of the filler and the mechanical properties - such as flexural strength, tensile strength and modulus - of the composites. The silane also reduces the filler's sedimentation tendency in the uncured polymer. GENIOSIL® GF 93 also greatly increases water (vapor) and corrosion resistance.. Due to the nature of the amino group, this substance reacts as a strong base. The silane hydrolyzes autocatalytically in the presence of moisture (Ethanol is released) to form silanols, which can subsequently react with themselves to produce siloxanes or can bind to inorganic substrates. As a typical amine, GENIOSIL® GF 93 can also interact with numerous organic polymers and thus function as a molecular bridge between organic and inorganic substrates.
