Beschreibung
Zusammenfassung:	The present invention relates to an epoxy modified polysiloxane composition obtainable by combining the following ingredients: a polysiloxane of formula (1), wherein each R is independently selected from the group comprising hydroxy, alkyl, aryl and alkoxy radicals having up to six carbon atoms, each R is independently selected from the group comprising hydrogen, alkyl and 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 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.
