<p>An agent (M) for a protective coating film for a mold which is applied on the region of the outer surface of a mold (9) except the portion for a cavity (10), which comprises a mixed fluid containing a urethane, methyl ethyl ketone and ethyl acetate and an agent for enhancing a curing rate comprising a mixture of an isocyanate-based compound and ethyl acetate; and a method for forming a protective coating film using the agent. The agent (M) for a protective coating film covers the mold (9) in such a state that it adheres to the outer surface of the mold and is not easily released from it and can protect the mold, as a protective film (11), against rust, damage and the like during its storage. The protective film (11) exhibits heat resistance at about 100°C and thus can satisfactorily endure the use at 70 to 80°C during stamping.</p> |
