ABSTRACT:
Wood surfaces are bonded together by heating and pressing with a bonding composition containing, on a bonding agent solids basis, from 10-70% of one or more sugars and from 90-30% of an aminoplast, and the bonding composition being used in an amount equal to the amount of straight condensation resin which would normally be used, i.e. the sugar replaces a quantity of condensation resin normally used thereby reducing the total quantity of condensation resin, thereby reducing cost and formaldehyde emissions and without any disadvantages.
