  • Publication number: 20230372995
    Abstract: 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.
