ABSTRACT:
A flame retardant, water-proof fabric useful for tenting, tarpaulins and protective clothing comprises a woven substrate formed from synthetic fibers intimately coated with a homegeneous composition of binders, flame retardants and plasticizers. The composition includes a blocked polyester/polyether urethane prepolymer which, when cured at a temperature sufficient to unblock the urethane, provides strong film integrity to bond the coating to the substrate and thereby increase the effective life of the product.
