SOLVENT - FREE COMPOSITIONS BASED ON HYDROXYSILYL ORGANOPOLYSILOXANE AND POLYALKOXYSILYL GROUP - CONTAINING AGENT CATALYZED BY ORGANIC IRON AND ZIRCONIUM DERIVATIVES. USE OF COMPOSITIONS FOR COATING THE IMPREGNATION OF MATERIALS BASED ON ASBESTOS OR CELLULOSIC OR SYNTHETIC DERIVATIVES

摘要

The object of the invention is to provide organopolysiloxane compounds, without solvents, comprising a hydrolyzyl-fused poly (phenylsiloxane), a branched poly (hydrogenosiloxane) having a hydroxyl-hydroxyl group, a crosslinking agent with a polyalkoxysilyl group and a catalyst (s). THE COMPOSITIONS, ACCORDING TO THE INVENTION, ARE CHARACTERIZED IN THAT THE CATALYST IS AN ORGANIC DERIVATIVE OF IRON OR ZIRCONIUM, SOLUBLE IN THE ORGANOPOLYSILOXANIC MEDIUM. / P P THE COMPOSITIONS ARE USED FOR COATING OR IMPREGNATION, AND ENABLE TO OBTAIN GOOD MATERIALS WITH GOOD ANTI-ADHERENT PROPERTIES, AS WELL AS JOINTS WITH GOOD HYDROFUGING PROPERTIES AND RESISTANT TO SOLVENTS. / P
