Properties: GENIOSIL® CS 2, when used as a component of organic/inorganic composites, improves the adhesion between the organic polymer and the inorganic fillers used. This imparts significantly improved flexural strength and impact strength to the composites. It also reduces water absorption and dirt pick-up significantly. GENIOSIL® CS 2 also liberates about 50 % less methanol than conventional adhesion promoters. Special features: GENIOSIL® CS 2 is an unsaturated alkoxysilane. It´s a clear, colorless liquid with a characteristically aromatic odor. It hydrolyzes in the presence of moisture under liberation of alcohol to form silanols, which can then react with themselves to form siloxanes. Having both silyl and unsaturated organic groups, GENIOSIL® CS 2 is able to function as a molecular bridge between organic and inorganic substrates. Application: GENIOSIL® CS 2 is principally used in the production of unsaturated polyester resin or polyacrylate composites to increase mechanical strength. GENIOSIL® CS 2 acts as a coupling agent by forming a chemical bridge between the organic resin and the inorganic fillers or pigments used, e.g. quartz, granite or even glass.
