Abstract (en)

[origin: EP0763387A1] A process is claimed for the prodn. of a film (I) to form a protective surface layer on a profiled object, in which a base film impregnated with a thermosetting impregnating resin (II) is coated with varnish (III). The novelty is that (a) resin (II) is an aq. condensation resin with a volatiles content of about 50 wt.% during coating, and the impregnated film has a volatiles content of 8-20 wt.% before varnishing; (b) varnish (III) is an aq. system based on an OH gp.-contg. acrylic polymer, polyurethane polymer or polyester copolymer contg. a crosslinker which not only crosslinks the binder but also promotes chemical bonding with resin (II) in the film; and (c) film (I) is dried to a final moisture content of 2-20 (pref. 4-10) wt.% before applying it to the profiled substrate.
