Novel neopentasiloxane compounds of the general formula Si[OSiR2Q]4 wherein R denotes a monovalent hydrocarbon or halo- hydrocarbon group and Q denotes a group R or a group comprising a block of at least two oxyalkylene units and having a terminal group containing a reactive hydrogen atom, not more than one Q denoting an R group. The invention also encompasses a film-forming composition comprising a curable polyurethane resin and the neopentasiloxane, and the use of the film-forming compositions to provide breathable (water vapour permeable) coatings on textile fabrics.
Nouveaux néopentasiloxanes de formule générale Si¢OSiR2Q!4, dans laquelle R est un hydrocarbure monovalent ou un groupe hydrocarboné halogéné, Q est un groupe R ou un groupe constitué d'un bloc d'au moins deux unités oxyalkylène et possédant un groupe terminal contenant un atome hydrogène réactif, un Q seulement pouvant désigner un groupe R. L'invention porte également sur une composition formant une pellicule, comprenant une résine de polyuréthane réticulable et le néopentasiloxane; utilisation des compositions formant la pellicule pour l'obtention de revêtements perméables à la vapeur d'eau, applicables sur les tissus.
