PROTECTIVE FILM AGENT AND METHOD FOR FORMING PROTECTIVE FILM

WIPO Patent Application WO/2005/080636

A1

An agent (M) for a protective film which comprises a liquid mixture of a urethane type compound, methyl ethyl ketone and ethyl acetate and a curing rate enhancing agent comprising an isocyanate type compound and ethyl acetate; and a method for forming a protective film which comprises applying the agent for a protective film on the outer surface of a mold (9) or on the region of the outer surface of the mold (9) except a specific portion as an article to be coated. The agent (M) for a protective film covers the mold (9) in such a state that it adheres to the outer surface of an article (27) to be coated and is not easily released therefrom, to protect the mold (9) against rust, stain, damage or the like during the storage thereof as a protective film (11). The protective film (11) has the resistance to a heat at around 100°C and thus satisfactorily withstands the use at a temperature of 70 to 80°C during molding, and exhibits improved resistance to the exfoliation and cutting by impact, resulting in no cracking or chipping of the protective film (11) in the case of the collision of the mold (9) with another member.
