CONSTITUTION: A liquid molding material prepared by adding a defoaming agent and a levelling agent to a liquid molding composition (e.g., liquid phenolic resin or epoxy resin). The addition of the defoaming agent and the levelling agent makes it possible to shorten a defoaming time in a molding stage markedly, to heighten the rate of production, provide a void-free molding of a good appearance and, in particular, minimize the reject when used as a sealant for precision parts such as electronic/electric parts. Therefore, this material can be used suitably in high reliability in the production of such parts.
