CAS No.: 3069-29-2

Properties: The use of GENIOSIL® GF 95 as an adhesion promoter in glassfiber reinforced or filler modified plastics increases filler dispersibility and improves numerous mechanical properties (e.g. flexural strength, tensile strength, modulus of elasticity) of the composites. Additionally, its use reduces the fillers' sedimentation tendency in the uncured polymer. The use of GENIOSIL® GF 95 in these materials also results in a markedly improved resistance to water (vapor) and corrosion. At the same time, the mechanical properties can be adjusted with even greater precision by means of the dialkoxysilyl group. As textile finishing agents, Silicones modified with GENIOSIL® GF 95 result in amino modified silicone fluids that are an ideal active ingredient in softener formulations for finishing fibers and textiles.

Special features: GENIOSIL® GF 95 is an alkoxysilane with an amino functional group. It´s a clear, colorless liquid with a characteristic amine odor. Due to the nature of the amino group, this substance reacts as a base. The silane hydrolyzes auto catalytically 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. As a bifunctional amine, GENIOSIL® GF 95 can also interact with numerous organic polymers and thus function as a molecular bridge between organic and inorganic substrates. An additional bonus deriving from the dialkoxysilyl group in GENIOSIL® GF 95 is that VOC (volatile organic compound) emissions during hydrolysis reactions are reduced by one third compared to trialkoxysilanes.

Application: GENIOSIL® GF 95 is mainly used in glass-fiber or glass-fabric reinforced polyesters and polyolefin molded parts, and as a surface modifier for fillers (e.g. glass or mineral wool, mica, talc, wollastonite, kaolin, christobalite, metal oxides) and pigments for various plastics, including epoxy resins, polyamides, polyacrylates, polyurethanes, ethylene/vinyl acetate polymers and many others. Other important applications include its uses as a silicone modifying building block for textile finishing and as an additive or primer for sealants, adhesives and coatings.
