Abstract
Abstract Process for producing water-emulsifiable air-drying paint binders, the binders, and the emulsions therefrom characterized in that in a first reaction step 10 to 35 percent by weight of a polyethylene glycol having an average molecular weight of between about 500 and 5000, and 5 to 25 percent by weight of a low molecular weight formaldehyde condensate of an alkyl phenol and/or aryl phenol obtained under alkaline conditions are reacted at from 100° to 160° C., and the reaction product condensed in a second reaction step at from 180° to 250° C. with 40 to 85 percent by weight of a natural or synthetic substantially hydroxy-free ester of unsaturated oil fatty acids and polyols; and the obtained product in a third reaction step processed to provide an alkyl resin or oil binder, the weight ratios and reaction conditions being chosen in order that the final product has a level of from about 4 to 12 percent by weight of polyethylene glycol and an acid value of 10 to 30 mg KOH/g. The binders of the process when emulsified and used in the preparation of a paint have excellent storage stability and provide cured paint coatings having, inter alia, excellent water resistance.
