ABSTRACT:
Environmentally preferred water-based coatings can be substituted for solvent-based coatings in commercial wood finishing processes without sacrifice of coating quality. Art-recognized discoloration of water-based coatings due to uneven leaching of chromophoric substances, such as natural tannins, is eliminated by contacting the surface with a water soluble anti-leachate compound selected from the group consisting of carboxylic acid salts, mono/polyfunctional amines and amine derivatives and their acid addition salts. The process allows for marked reduction of VOC emissions from commerical wood finishing operations.
