ABSTRACT:
Thermally curable liquid sealants for impregnating the pores of cast metal articles and powdered metal articles consist of a combination of polymerizable components including at least about 15% by weight of a water emulsifiable unsaturated polyester and no more than 20% of a monofunctional methacrylate or acrylate monomer. The sealants when cured, have low weight loss when tested for heat resistance, acceptable weight gain or loss when tested for chemical resistance upon submersion in water, brake fluid, antifreeze and methanol alcohol.
