How has Gold Coat been tested?
Gold Coat has been tested to a modified AWPA E12 test standard. In the test program, test coupons were fastened to pieces of treated and non-treated material and placed in a corrosion chamber for 120 days. The chamber was kept at a steady state of 49 degrees Celsius and 90 percent relative humidity. After the 120 days the coupons were removed from the chamber, separated from the wood and cleaned to record the material weight loss. Weight loss measurements included both total sample weight loss and base material (steel) weight loss. Final product testing was conducted at Michigan State University with the assistance of Dr. Pascal Kamdem; a noted industry leader on this topic. The test methodology used was developed in conjunction between USP and Dr. Kamdem based on both parties extensive experience with accelerated corrosion testing. By developing a test program which measures base material weight loss, the true effectiveness of a coating system can be measured.
