GENIOSIL® CS 2

Silane Preparation


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.
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.






 

Storage

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
