PURPOSE:To prepare a release agent of long release life and superior film forming properties and release properties by blending a highly fluorinated organic compound with a kind of fluoride including fluoroalkyl or fluoroalkenyl. CONSTITUTION:A release agent is composed of a mono-substituted ethylene containing fluoroalkyl or fluoroalkenyl, or a homologous copolymer or a mutual copolymer of (meth)acrylic acid ester, or a copolymer copolymerizable with (meth)acrylic ester, and a highly fluorinated organic compound. Said release agent is of superior film forming properties, and can form a uniform film on a molding surface of complicated shape or large size, and even a release agent of 0.1% concentration or so can exercise superior release properties to enhance the dimension accuracy of a molded product. |
