The present invention is directed to a two package coating composition, comprising:
(A)
(a1) an acrylic resin having acid and hydroxy groups; and
(a₂) additives selected from the group consisting of solvents, UV-stabilizers, antioxidants, catalysts, flow agents, hindered amine light stabilizers and mixtures thereof; and
(B)
(b₁) a polycarbodiimide;
(b₂) optionally a crosslinker selected from the group consisting of polyisocyanates, aminoplasts, and mixtures thereof; and
(b₃) additives selected from the group consisting of solvents, flow agents, findered amine light stabilizers, UV-absorbers, and mixtures thereof;
a method of coating an article therewith and the coated article. The coating composition is used as a clearcoat with improved rheology control and no striking in which forms films with excellent appearance and sag resistance.
