Abstract
An adhesive composition comprising a core shell vinyl ester and a urethane acrylate, which is suitable to be applied to a rough or uneven surface of a substrate to render a smooth surface. The present adhesive composition is particularly suitable to coat large objects made through additive manufacturing to form molds or prototypes.
Claims11
A polymer composite article comprising:
- a substrate comprising a polymer body having a surface with a surface profile in the range of 1.0 to 10 mm;
- and,
- an adhesive coating on the surface of the polymer body, wherein the adhesive coating comprises core shell vinyl ester resin, wherein the adhesive coating has a surface profile of less than 0.10 mm after applying the adhesive coating.
A method of manufacturing a polymer composite article comprising:
- (a) forming a substrate comprising a polymer body having a surface with a surface profile in the range of 1.0 to 10 mm;
- (b) applying an adhesive coating on the surface of the polymer body, wherein the adhesive coating comprises core shell vinyl ester resin;
- (c) curing the adhesive coating, wherein the adhesive coating has a surface profile of less than 0.10 mm after applying the adhesive coating.
