PURPOSE:To obtain a hot mold releasing agent having an excellent mold release property in a wide range of temperatures, especially, in hot, by using a polymer having an organopolysiloxane component in the main chain or a side chain as a principal component. CONSTITUTION:A hot mold releasing agent comprising a polymer having an organopolysiloxane component of the formula in the main chain or a side chain as a principal component. In the formula, R and R' are each methyl, ethyl, propyl, phenyl or the like, and n is desirably 8-12. Said polymer having said component in the main chain is a polymer having a basic skeleton comprising a polyester, a polyurethane or a polyamide. Said polymer having said component in a side chain is a polymer having said component in the side chain of its basic skeleton. According to the purpose of its use, the hot mold releasing agent may contain other additives such as a binder, dye, pigment, surfactant or antioxidant. |
