MASKING TAPE OR SHEET FOR GALVANIZING

摘要

PURPOSE:To provide a masking tape for plating which permits simple and quick masking, by providing a surface film layer having chemical resistance on one surface of a sheetlike base material which does not melt in a molten zinc bath and forming a self-adhesive layer on the other surface. CONSTITUTION:A masking tape or sheet 1 is formed by providing a surface film layer 2 with an adhesive agent (or a self-adhesive agent) 5 on one side of a sheetlike base material 3, and providing a self-adhesive layer 4 on the other. The layer 2 is formed of a plastic film or the like having chemical resistance, and is made to about 0.01-0.1mm. thick. Org. or inorg. fibers which do not melt in a molten zinc bath are used for the material 3 and the amt. of said fibers to be used is about 20-100g/m<2>. A polyacrylic acid self-adhesive agent or the like is used for the layer 4, which preferably carbonizes in about 2-4min in the zinc bath and the carbonized product of which sticks tentatively on the adherend.
