Study on practical application of fluororesin powder coating (part 1): Evaluation of basic physical properties and weatherability

Abstract

Basic physical properties and weatherability were evaluated in order to evaluate the practicality of the fluororesin powder coating. As a result, the basic physical properties of various powder coatings were almost the same as those of solvent-based fluororesin coatings (PVDF). As a result of the accelerated weather resistance test and outdoor exposure test in Okinawa, a difference in weatherability was observed depending on the type of powder coating, and a fluororesin powder coating with the same performance as PVDF was confirmed. One of the causes of deterioration of the powder coating was presumed to be photocatalytic reaction.
