METHOD FOR COATING AN ARCHITECTURAL TEXTILE WITH AT LEAST ONE LAYER OF A SILICONE ELASTOMER USING AN AQUEOUS SILICONE EMULSION AND AN ARCHITECTURAL TEXTILE WITH SUCH A COATING

摘要

The invention relates to the production of silicone membranes for architectural use, by means of coating an architectural textile with a silicone, in particular, but not exclusively on a glass fabric. The aim of the invention is a method in which the deposition on the architectural textile may be easily and rapidly achieved with a coating rate of less than 40 g/m<2>. Said aim is achieved whereby said method comprises the following steps: deposition on said architectural textile of at least one layer of an emulsion of polyorganosiloxane (POS), which may be cross-linked to give an elastomer by polyaddition and comprising: (A) a POS with =SiVinyl groups, (B) a POS with =SiH groups, (C) a special adherence promoter (polyvinyl alcohol) or POS(OH), (D) a catalyst, (E) at least one surface active agent, (F) optionally a POS resin with =SiVinyl groups, (G) optionally a cross-linking inhibitor, (H) optionally a pH stabilising agent,(I) optionally a formulation additive, (J) optionally a charge and (K) water, with the condition that 0.05 < (C)< 4 % by weight of the silicone phase, followed by cross-linking such that the weight proportion of the coating as a proportion of the dry weight of the architectural textile is less than 0.2 and preferably between 0.05 and 0.11.
