AQUEOUS COATING COMPOSITION HAVING IMPROVED ACID ETCH AND MAR RESISTANCE
摘要
An aqueous coating composition having a pH of 6.0-10.0 comprises 30 % to 70 % by weight of film-forming binder and correspondingly 70 % to 30 % by weight of an aqueous liquid carrier for the binder; wherein the binder comprises: a. 20 % to 95 % by weight, based on the weight of the binder, of a urethane oligomer having a weight average molecular weight of 300 to 2500 and having acid functionality and neutralized with an amine and to form a water-dispersible product; and b. 5 % to 80 % by weight, based on the weight of the binder, of a water-compatible alkylated melamine formaldehyde crosslinking agent; finishes formed from the composition have good gloss and distinctness of image and excellent acid etch and mar resistance.
