Abstract: A method of coil coating a metal strip that includes applying to the metal strip, a coating composition that includes a binder containing a) a polyol component, which is soluble or dispersible in water; and b) a polyisocyanate component, which is soluble or dispersible in water and has blocked isocyanate groups. Metal substrates coated according to the method can be used to make articles.

Abstract: A two-component coating composition that includes (A) a first component containing an acid functional aliphatic polyester polyol having an acid number of at least 20 mg KOH/g and a hydroxyl number of from 50 to 500 mg KOH/g, and (B) a second component comprising one or more polyisocyanates. The composition can be used to coat metal substrates by (i) mixing components (A) and (B) in the above-described composition to form a mixture; and (ii) applying the mixture to a surface of a metal substrate.
