Abstract
A method for improving physical characteristics of cured container coatings subjected to steam processing is described herein. The method comprises applying a coating composition including a first component which is a carbamate functional compound and a second component which is a compound having a plurality of functional groups that are reactive with said carbamate group(s) on the carbamate functional compound. The coating composition is baked to form a cured film on the container. The container is filled and subjected to steam processing conditions suitable for food and beverage processing.
Claims15
A method for obtaining cured container coatings resistant to degradation caused by steam processing, comprising
- a) applying to a container, a coating composition comprising a first component which is a primary carbamate functional compound and a second component comprising a compound having a plurality of functional groups that are reactive with said carbamate group(s) on the carbamate functional compound,
- b) baking said coating composition to form a cured film on the container,
- c) filling the container having a cured film thereon, and
- d) subjecting the filled container to steam processing at temperatures between 80.degree. C. and 130.degree. C. at pressures between 20 and 60 psi, for times ranging from 15 to 90 minutes.
