Manufacture of coated split-resistant improvement webs from paper having unit weight 60 g/m2
Abstract
Abstract A method for manufacturing split-resistant improvement webs from paper having a weight per unit area of ≦60 g/m 2 which has a hardened synthetic resin on the decorative side and which are used for gluing to the surface of wood-based panels wherein a solution or dispersion of a hardenable impregnating resin is first applied to the paper using a metered-roller application in an amount between about 8% based on the solids content of the resin (of the weight of the paper) but less than an amount such as to assure that the resin does not penetrate to the reverse side of the paper. The impregnated paper is then dried, decoratively printed, and then coated with a solution or dispersion of a hardenable resin followed by drying and hardening. Such webs are easily handled and can be rolled up and the method allows the use of conventional paper which does not have to be specially treated.
