摘要
Production of architectural silicone membranes comprises coating an architectural textile with an aqueous emulsion of a polyaddition-crosslinkable polyorganosiloxane composition containing 0.005-10 wt.% of an adhesion promoter which is a protective hydrocolloid or a hydroxy- and ammonium-functional silane or POS, and crosslinking the product to give a coating/textile dry weight ratio below 0.2. Production of architectural silicone membranes comprises: (a) coating an architectural textile with an aqueous emulsion containing a polyorganosiloxane (POS) with at least two silicon-bonded C2-C6 alkenyl group, a POS with at least three silicon-bonded hydrogen atoms, 0.005-10 wt.% of an adhesion promoter which is a protective hydrocolloid or a hydroxy- and ammonium-functional silane or POS, a catalyst, a surfactant, optionally a POS resin with at least two alkenyl groups, a crosslinking inhibitor, optionally a pH-fixing agent, optionally one or more formulation aids and optionally a filler; and (b) crosslinking the product to give a coating/textile dry weight ratio below 0.2. An Independent claim is also included for a membrane produced as above.
