<p>Flammable foundry coatings are disclosed in which the carrier liquid is safer to handle than the previously used types e.g. isopropanol, and which also burns off more satisfactorily. The carrier liquid is a mixture of an essentially aliphatic hydrocarbon liquid of flash point greater than 32.degree.C, e.g. an aliphatic petroleum distillate, and a mono alkyl ether of a polyhydric alcohol, e.g. ethylene glycol monoethyl ether("Oxitol").TM</p> |
