Abstract

Procedure for obtaining polyurethane foam materials with integrated skin, characterized in that it involves depositing on the internal walls of the silicone elastomer molds, one or several layers of organic solutions of film-forming polymers based on silicone resins modified by organic compounds, leaving evaporate the diluent or diluents they contain in order to form pre-hardened films, introduce classic mixtures into the molds that lead to polyurethane foams with integrated skin and remove after foaming the molded materials whose surface has a homogeneous and adherent coating coming from the Integral transfer and complete polymerization of pre-cured films.
