Making timber materials with modified veneers involves impregnating veneer with aqueous setting composition with interlaceable urea compound(s), pressing at high temperature, gluing, sticking with support/further veneer layer to timber

摘要

The method involves impregnating a veneer with an aqueous setting composition with at least one interlaceable urea compound with at least one N-bound group of the formula CH2OR with R standing for hydrogen or C1-C4alkyl and/or a 1,2 Bishydroxethane-1,2-diyl group bridging the two nitrogen atoms of the urea and at least one catalyzing substance, pressing the impregnated veneer at high temperature, gluing the pressed veneer and/or a support and sticking the glued veneer to a support or further veneer layer to the timber. An independent claim is also included for a wooden material manufactured by the inventive method.
