UV curable paint coating method and UV curable film manufacturing method

摘要

A method for applying an ultraviolet curable coating material and a method for producing an ultraviolet cured film include the steps of: supplying an ultraviolet curable coating material containing an ultraviolet curable acrylic monomer into a mixer under a condition of greater than or equal to 8 MPa without diluting the ultraviolet curable coating material with an organic solvent; supplying carbon dioxide with a critical pressure or more into the mixer; mixing the ultraviolet curable coating material and the carbon dioxide supplied into the mixer to form a mixed fluid; spraying the mixed fluid under a condition of a critical pressure or more of the carbon dioxide to form a coating film; and irradiating the coating film with ultraviolet rays to form an ultraviolet cured film.
