Abstract
PURPOSE: To provide resin compsn. having improved water resistance and low- temperature stability and useful as plywood adhesive, obtd. by a method wherein partially methylated methylol-melamine is co-condensed with phenol-formaldehyde precondensate.
CONSTITUTION: There are provided resin compsns. obtd. by a method wherein partially methylated methylol-melamine (obtd. by reacting not less than 1.8mol of formaldehyde with 1mol of melamine) is co-condensed with phenol-formaldehyde precondensate (obtd. by adding 3mol formaldehyde to 1mol phenol and reacting not less than 2.4mol formaldehyde with 1mol phenol) in such a proportion that a final product contains not less than 18wt% melamine and not less than 8wt% phenol. When formaldehyde is used in an amount of less than 1.8mol per mole melamine, the low-temperature stability of the resin compsn. obtained is lowered.
