This technology relates to refractory coatings used in metal casting by the foundry industry. Refractory coatings are often used to coat foundry cores and molds for the purpose of improving the quality of castings formed in connection with the cores or molds, particularly at the surface of the casting. Whereas traditional coatings comprise water based solvents that require excessive drying times or HAPs that emit hazardous VOCs, preferred embodiments of the present invention comprise refractory coatings having VOC-exempt ester based solvents, such as a dimethyl carbonate (DMC). Other preferred embodiments of the present invention comprise methods for reduction of VOC content in a foundry article.

This invention relates to compositions and methods for reduction of formaldehyde odor and emission during the production and curing of cores and molds, particularly those cores and molds of the foundry industry which comprise ester curable phenolic binders. More specifically, included herein is an ester-curative comprising an ester and resorcinol which, when provided in a composition with a resin and an aggregate, effectively scavenges unreacted formaldehyde thereby reducing emission and odor of the same from the composition.
