ABSTRACT:
A chinawood oil-phenolic resin condensate particularly useful in high solids content solution coatings is produced by heat reacting: (1) an o-cresol-formaldehyde condensate containing about 1 to about 2 mols of formaldehyde per mol of o-cresol; with (2) from about 80% to about 95% of its weight of chinawood oil; and (3) from 2% to 10% of the total weight of an alkyd resin which is a condensate of a polyethylenically unsaturated monocarboxylic fatty acid containing from 16-22 carbon atoms with about 0.5 mol per mol of said acid of an aliphatic glycol having a molecular weight of less than about 200.
