ABSTRACT:
This invention relates to a method of sealing the porous surfaces that can be generated during the manufacturing and processing of molded plastic parts. Liquid thermoset coatings are applied to preheated parts and cured to create a barrier on the surface to gasses generated during heat curing of subsequently applied surface coatings. The liquid coating may be comprised of polyurethane forming components; those components in combination with unsaturated polyester resins; vinyl ester resin compositions; coatings derived from hydroxyl or carboxyl containing oligomers reacted with alkylated urea-formaldehyde, melamine-formaldehyde, and/or benzoquanamine-formaldehyde resins; and oligomers containing carboxyls reacted with triglycidyl isocyanurate.
