QUV (ASTM D4329) 5000+ Hours

James Hardy, an Australian Concrete fabricator, ran tests on reinforced concrete panels coated in WC-1 and WC-1A.  The tests were conducted in a Q-Panel QUV/se test chamber.  The testing was to determine the possible life cycle for the coatings in the out door Australian environment.

After over 5,000 hours of QUV exposure the WC-1 and WC-1A panels demonstrated over 90% gloss retention and a delta E of less than 2.

What this means is open to discussion as the test profile only rates up to 2000 hours.  2000 hrs with 90% gloss retention indicates a probable life cycle of over 30 years.  Our coating exceeded that by 2.5 time but no one know what that means.


QUV (ASTM G53) 2000 Hours


Panels were subjected to 8 hours of ultraviolet light at 140°F (60°C), then 4 hours condensation at 113°F (45°C). All panels were coated at 10 mils DFT. Gloss retention figures are more important than initial gloss as the retention percentage is indicative of a coating's ability to retain both color and gloss when exposed to sunlight and rain in either architectural, aerospace, marine or industrial environments.


Gloss
retention figures in excess of 90% were observed and are considered excellent.



Kesternich Cabinet (DIN 50018) 1000 Hours

The Kesternich Cabinet Test is a very harsh test of a coating's chemical resistance.  All panels were coated at 15 mils DFT and exposed to sulfuric acid fumes and sodium bisulfate fumes at 100°F for 1000 hours. The results from this test are indicative of very good to excellent performance.  Historically, test of this type will completely destroy inorganic zincs and aggressively attack organic zincs.
