Abstract
Heat-curable, aqueous synthetic resin mixtures for coating woodworking materials, based on etherified melamine/formaldehyde condensates and aqueous synthetic resin dispersions, a process for the preparation of these mixtures and their use for coating woodworking materials.
Claims6
A finishing foil which comprises an absorptive paper impregnated with an aqueous synthetic resin mixture containing
- (A) from 5 to 50% by weight of an etherified melamine/formaldehyde condensate having a molar ratio of melamine to formaldehyde of from 1:4.5 to 1:5.8,
- (B) from 5 to 60% by weight of a copolymer which is present in the form of an aqueous dispersion, is crosslinkable by a condensation reaction and consists of predominant amounts of alkyl acrylates and/or methacrylates, minor amounts of comonomers having groups capable of crosslinking and other components, and
- (C) from 10 to 50% by weight of urea,
- the amount of components (A), (B) and (C) summing to 100% by weight and being based on the solids content of the aqueous synthetic resin mixture.
