Method for promoting curing of primer of heavy corrosion-proof steel material

Abstract

PURPOSE: To rapidly promote the curing of the humidity curable primer of a heavy corrosion-proof steel material in low cost by a simple means. CONSTITUTION: After the paint of the primer film 2 applied to a steel material 1 is subjected to dry curing, the water retention sheet of a primer curing promoting sheet consisting of the water retention sheet and a moisture impermeable film or a water impermeable and moisture permeable film or the water impermeable and moisture permeable film 3 of a primer curing promoting sheet 8 consisting of the water impermeable and moisture permeable film 3, a water retention sheet 4 and a moisture impermeable film or a water impermeable and moisture permeable film 5 or the water impermeable and moisture permeable film of a primer curing promoting sheet consisting of the water impermeable and moisture permeable film, a water and moisture impermeable film is brought into contact with the surface of the primer film 2 or allowed to approach the surface of said film 2. If necessary, the primer coated steel material is heated. COPYRIGHT: (C)1992,JPO&Japio
