CURABLE COATING COMPOSITIONS FROM EMULSIONS OF ELASTOMERIC POLYMERS AND POLYURETHANE DISPERSIONS

摘要

A curable coating composition comprises:(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.Methods for preparing the curable coating compositions are also disclosed. The curable coating composition and the cured coatings derived from the reaction product of this composition are useful as fabric coatings, and in particular for decreasing air permeability of the coated fabrics at relatively lower coating weights.
