摘要: A high solids, organic solvent based, sprayable coating composition which is capable of acid catalyzed crosslinking composed an active hydrogen-containing resin, a curing agent present externally and/or internally as part the resin; and catalytic amount non-ionic ester sulfonic acid. The represented by following structural formulas: ##STR1## wherein: Z radical selected from group consisting amino radical, said being connected to sulfur atom carbon atom; W C 1 -C 18 alkylene, 2 alkenylene; V hydroxyl substituted alkenylene, R , 3 4 5 are independently hydrogen or radical.
