GENIOSIL® CS 2
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.
1. General processing information
GENIOSIL® CS 2 dissolves readily in standard organic solvents, but is practically insoluble in neutral water.
GENIOSIL® CS 2 hydrolyzes in acidified water (pH approx. 4 - 5) to silanols, the diluted solutions of which remain stable for some time.
2. GENIOSIL® CS 2 in Composites
To modify organic/inorganic composites, 1 to 3 % GENIOSIL® CS 2 is added to the organic resin along with conventional additives, such as peroxide and accelerator. The final products can then be manufactured in the usual way with conventional equipment.
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.
