Title:
PEELING METHOD OF COATING FILM
Document Type and Number:
Japanese Patent JP2015182024
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To efficiently peel a coating film, even if there is no place for exposing a base material.SOLUTION: In a method for peeling a coating film 12 applied on a conductive base material 10, an aqueous penetrant 20 is applied on a surface of the coating film 12, and a portable type electrode 40 is brought into contact with a surface of the applied aqueous penetrant 20, and a direct current is made to flow to the conductive base material 10 via the aqueous penetrant 20 and the coating film 12 from the portable type electrode 40 with the portable type electrode 40 as a positive electrode and the conductive base material 10 as a negative electrode. Here, the aqueous penetrant can include at least one of a solvent, alcohol, glycol ether, keton, ether, an organic amine compound and a chelate agent and water.
