The second composite coating layer is preferably a polyurethane, a polysiloxane, and an epoxy resin which acts as a filler and adhesion promoter. A third coating layer is formed of a polymeric polyurethane material coated on the second composite layer. A method of producing the coated textile fabric is also disclosed. A heat sealing die for forming sealing beads to seal such coated textile fabrics to form air holding devices is also disclosed.
