Patent

CA 1337308

A blocked acid catalyst of an aromatic sulfonic acid blocked with amino methyl propanol and coating composition containing the blocked acid catalyst are disclosed. In particular, the coating composition comprises about 40-85% by weight of a film forming binder and about 15-60% by weight of an organic liquid carrier and contains in addition about 0.1-6.0% by weight of a curing catalyst. The catalyst consists essentially of an adduct of an aromatic sulfonic acid reacted with 2-amino- 2methyl-1-propanol. The film forming binder comprises about 40-90% by weight, based on the weight of the binder, of an acrylic polymer containing reactive hydroxyl, glycidyl, amide groups or mixtures of these groups and about 10-60% by weight of an amino resin crosslinking agent.
