PURPOSE:To enhance the adhesion, efficiency and uniformity of treatment of the coating by providing the grinds of a thermosetting resin mold 5-100 mesh in particle size. CONSTITUTION:The polishing material is composed of the grinds of 5-100 mesh in particle size of a thermosetting resin mold. The adhesion to the metal surface prior to coating is thus improved and the peeling off of coated film is facilitated. |
