Abstract
A coating composition includes: (a) a polymeric resin including hydroxyl functional groups; (b) a polyisocyanate crosslinker; (c) a thiol including at least 2 active hydrogen groups, where the active hydrogen groups include a thiol group or a combination of a thiol and a hydroxyl group; and (d) a tin-based catalyst. The ratio of the number of moles of thiol to the number of moles of tin in the coating composition is less than or equal to 100:1 and the amount of (d) the tin-based catalyst is less than or equal to 0.25% by weight relative to the total resin solids, and/or the ratio of the number of moles of thiol to the number of moles of tin ranges from 3:1 to 50:1 and the amount of (d) the tin-based catalyst is less than or equal to 0.4% by weight relative to the total resin solids.
