PURPOSE: A cold-curing two-pack type urethane paint presenting sufficient curability even at -10W0°C and excellent in corrosionproofness, which comprises a specified higher amine and a specified polyisocyanate.
CONSTITUTION: A paint comprising a higher amine of MW200W2,000 having in one molecule 3W8 functional groups, of which one or two consist of amino groups and the balance consists of hydroxyl groups, and a polyisocyanate cpd. of MW250W 3,000 having at least two isocyanate groups for one molecule, for which when a higher amine having two amino groups is selected as soln. A, a polyisocyanate cpd. of MW700W3,000 is taken as soln. B. In order to enhance corrosionproofness of said paint, it is pref. for one or both of the higher amine as soln. A and the polyisocyanate cpd. as soln. B to have an ether linkage in the molecular structure.
