A low tack, low VOC gel coat is disclosed comprising a unsaturated polyester resin derived from maleic anhydride and up to about 30% of an organic solvent. The resin is characterized by: a viscosity of less than or equal to about 1750 cp at 70% NVM in styrene; a glass transition temperature greater than or equal to about 11&deg; C.; and a weight average molecular weight less than or equal to about 6,050. A process for making such a gel coat is also disclosed.

Low VOC low tack gel coat resin

Polyester resin-based molding compositions, and methods for making and using the same, are described which have an improved maturation profile upon addition of a thickening agent. The improved maturation profile results from the presence of at least one multivalent metal salt of a non-fatty acid or anhydride in the molding composition added in accordance with the invention.
