Abstract

The existing freeze thaw test standard for waterborne coatings ASTM D-2243-95 was analyzed to evaluate heat transfer criteria for the test. Temperature data was collected from various locations in cans of a coating, a resin, and water continuously throughout the course of multiple freeze thaw cycles. Variables included whether or not air was moving past the can, comparison between waterborne latex and urethane resins as well as antifreeze levels in the coating. The temperature data was ultimately processed into charts depicting temperature as a function of time. Calculations were made to determine the total amount of heat energy needed to equilibrate a can using a calorimetric approach. Viscosity measurements were also taken to determine pass/fail on freeze thaw tests.
