Abstract:  Zero VOC compositions are described and may include: one of vinyl ester solids, unsaturated polyester solids (e.g., isophthalic polyester, orthophthalic polyester, terephthalic polyester, and mixtures thereof), and mixtures thereof; polymerizable solids (e.g., a monomer, an oligomer, and mixtures thereof); and/or at least one photochemical catalyst. Zero VOC compositions may be produced by: heating polymerizable solids to a range of about 300.degree. F. to about 500.degree. F.; and adding one of vinyl ester solids, unsaturated polyester solids, and mixtures thereof. Additional steps may include reducing the heat to about 70.degree. F. to about 100.degree. F. and adding at least one photochemical catalyst and/or at least one additive. Zero VOC compositions may be curable without requiring evaporation of a VOC there from upon exposure to ultraviolet light and/or mixing with at least one thermal catalyst.
