ABSTRACT:
The aqueous polyorganosiloxane emulsion, in particular for the coating of textiles or similar materials, which comprises an organopolysiloxane formula which is a precursor of the elastomer comprising a polydiorganosiloxane, preferably an inorganic filler, a catalyst and optionally a crosslinking agent, in the absence of surfactant in this formula, is characterized in that the organopolysiloxane formula is in emulsion in an aqueous protective hydrocolloid solution and in that this emulsion is obtained by direct emulsification of the complete organopolysiloxane formula in the aqueous protective hydrocolloid solution. The protective hydrocolloid is preferably a poly(vinyl alcohol) (PVA) or a PVA mixture.
Preparation method relating thereto, coating process using these emulsions and products thus coated.
