Abstract
Process for producing water-emulsifiable paint binders based on select blends of alkyd resins and the improved emulsifiable paint binders therefrom are described. 30 to 75 percent by weight of aminoaldehyde resin is first reacted with 25 to 70 percent by weight of polyethylene glycols having an average molecular weight of from 500 to 3,000. Thereafter, 5 to 30 percent by weight of the polyethylene glycol modified aminoaldehyde resin is reacted with a blend of alkyd resins, one of the alkyd resins of the blend having a low acid number and another of the alkyd resins of the blend having a high acid number. The co-condensate of modified aminoaldehyde resin and alkyd resins when emulsified in water provides an emulsion with fine particles and excellent stability, rendering the emulsion particularly suitable for use in stoving paints.
