APPLICATION OF ANTI-CORROSIVE AGENT

PURPOSE:To prevent the flowing-down of paint at the time of working, by mixing a foaming agent with an anti-corrosive agent sprayed along with compressed air. CONSTITUTION:An anti-corrosive agent A consisting of a solid component such as petroleum sulfonate, lanolin metal salt, oil or wax and a solvent component such as toluene or xylene and compounded with anti-corrosive pigment and a plasticizer etc. if necessary is mixed with a foaming agent such as propane, LPG or azobisisobutyronitrite to fill a tank or cylinder 1. At the time of painting, the resulting mixture is sprayed to the surface of an article to be painted simultaneously with compressed air or in a state mixed with compressed air immediately before painting. Whereupon, the foaming agent in the paint sprayed to the surface of the article to be painted is evaporated and a large number of air bubbles of the anti-corrosive agent are generated by the action of the surface tension of said foaming agent to be adhered to the surface of the article to be painted and, therefore, the dripping of the paint is suppressed by high holding force possessed by the air bubbles.
