摘要:
The invention relates to a process wherein A a heat curable froth or foamable mixture of polyurethane reaction components is applied to the back of a fabric, B the coated fabric is heated to form a gelled, tack-free and storable foam-backed fabric and C the fabric is shaped and cured using a hot molding process. The polyurethane formulation contains a hydroxy functional ester of an acrylic or alkyl acrylic acid and a free radical initiator.
