Abstract
An oil-based release agent of the present invention contains a petroleum-based hydrocarbon solvent (a) and a high temperature adhesive (b), is applied to a metal die used for die casting or casting, has high adhesion and high lubricity even with respect to a metal die at a high temperature particularly of 300° C. or higher, and can prevent seizure. In addition, the present invention provides a method for applying the oil-based release agent of the present invention by controlling an adhesion amount thereof by micronization and speed-control thereof with respect to a metal die at a high temperature, and an electrostatic application method.
