Abstract

Additives for urea-formaldehyde resins or adhesive mixtures containing these resins comprise melamine salts of organic acids chosen from 1-4C saturated aliphatic mono- or dicarboxylic acids, citric acid and / or phthalic acid added to increase the waterproofing of joints between wood products bonded together using these adhesives. Preferably the acid is formic acid or acetic acid.
