Process for producing molded article

摘要

Process for producing a molded article comprising pouring or injecting a liquid molding material into a mold in the presence of a surface-treating agent comprising a contact angle-reducing substance under the condition that the contact angle between the liquid molding material and the inner surface of the mold is not more than 30°, and curing the liquid molding material; surface-treating agent comprising a contact angle-reducing substance which reduces the contact angle between the liquid molding material and a flat plate made of the same material as the mold to not more than 30°; method for reducing surface voids during molding, comprising using the above surface-treating agent; and use of the above surface-treating agent for reducing surface voids. The molded article has a shape accurately corresponding to the shape of an inner surface of a mold.
