Abstract
Phenolic novolak chemistry, the basis of coating and curing processes employed in resin-coated sand technology, has been studied with differential scanning (calorimetry), degree of cross-linking, gas evolution, and infra-red spectrum testing methods. Various thermal properties of phenolic resin during heating at different temperatures have been obtained. It is suggested that the methods employed in this paper could be used to optimise hot-coating and curing processes associated with Croning shell sand.
