Abstract
Low VOC vinyl ester resins exhibit improved cure in an oxygen containing environment. The vinyl ester resins comprise the reaction product of an epoxy resin having at least two epoxy groups per molecule; a polybasic anhydride; unsaturated monobasic acids comprising up to about 10 molar percent dicyclopentadienyl monomaleate based on the total unsaturated monobasic acids, wherein the vinyl ester resin has a viscosity of less than about 1200 cp measured at a shear of 500 s.sup.-1 in styrene at 70% non-volatile matter. Barrier coats and gel coats comprising such vinyl ester resins have acceptable tackiness and physical characteristics. A process to make such vinyl ester resins is also described.
