Abstract
A method for coating a substrate comprises the steps of:(I) applying a layer on the substrate of a curable composition comprising:(A) a water continuous emulsion comprising a curable elastomeric polymer having a viscosity of 0.5-1,000,000 KPa-s and a glass transition temperature up to 50° C.,(B) an aqueous polyurethane dispersion, and optionally(C) a cure agent(II) exposing the layer to air for sufficient time to form a cured coating. Coated fabrics prepared accordingly are particularly useful in the construction of automobile protective airbags or other such inflatable coated textile devices.
