Abstract
The present invention relates to an epoxy modified polysiloxane composition obtainable by combining the following ingredients:—a polysiloxane of formula (1), wherein each Ris independently selected from hydroxy, alkyl, aryl or alkoxy radicals having up to six carbon atoms, each Ris independently selected from hydrogen, alkyl or aryl radicals having up to six carbon atoms and, wherein n is selected so that the molecular weight for the polysiloxane is in the range of from about 400 to 10,000; with formula (1)—an epoxy resin having more than one 1,2-epoxy groups per molecule with an epoxy equivalent weight in the range of from 100 to about 5,000; and—an amino hardener component having active hydrogens able to react with epoxy groups in the epoxy resin to form polymers containing hydroxyl groups, which are able to react with the silanol groups of hydrolyzed polysiloxane to form a polymer network, wherein the epoxy chain polymers and polysiloxane polymers polymerize to form a cured epoxy modified polysiloxane polymer composition.
