Buster & Punch product shows good corrosion performance
AWL Ltd are pleased to have helped Buster & Punch Ltd confirm durable corrosion performance for their high-end decorative finishes using the CASS corrosion test. What is CASS? CASS (Copper Acid Salt Spray) testing according to ISO 9227:2017 or ASTM B368 is chosen when validating the corrosion performance of decorative coatings such as copper, nickel, and chromium for resistance to pin-holing, loss of adhesion, discolouration and other surface effects. The test is more aggressive than neutral salt spray testing and has also been found suitable for testing anodic and organic coatings on aluminium substrates at AWL Ltd using various corrosion test chambers such as the one shown in the picture below.
