METHOD FOR SUPPLYING MIXING REACTION CURABLE MATERIAL

PROBLEM TO BE SOLVED: To supply a main agent of a mixing reaction curable material into a mixing chamber while reducing the mixing of air bubbles with the main agent, to make it possible to use a mixture obtained by the mixing with a curing agent without generating the adverse effect caused by the mixing with air bubbles, and to facilitate the control of a color to simply enable color changeover. SOLUTION: A material supply line has a main agent tank 10, a curing agent tank 20 and an additive tank 30. The main agent based on a polyol is stored in the main agent tank 10, and an isocyanate compound of the curing agent is stored in the curing agent tank 20. An internal release agent and a colorant inferior to the compatibility with the polyol among the additives of the main agent are not compounded with the main agent, in order to prevent the mixing with air bubbles due to strong stirring and stored in the additive tank 30 as third supply components. These components are supplied to the mixing chamber of a spray gun through a line L3 separate from a main agent supply line L1a and a curing agent supply line L2a to mix the main agent, the curing agent, the internal release agent and the colorant.
