1. A coating composition comprising:
(a) a polyisocyanate; (b) a polymeric polyol; (c) a polyaspartic ester corresponding to the formula:wherein: X is an aliphatic residue, R1 and R2 are organic groups that are inert to isocyanate groups at a temperature of 100° C. or less and may be the same or different organic groups; and n is an integer having a value of at least 2; and
(d) a chelated tin (IV) compound, wherein (b) and (c) are present in the coating composition at a weight ratio of at least 1:1. |
