SOLVENT and CHEMICAL RESISTANCE PROPERTIES After 50 Days Exposure
Typical Wearlon® Silicone Epoxy Coatings (Wearlon® 2020.90 and Wearlon® 2020.98)

These tests have been conducted on cold rolled steel Q-panels that have been surface prepared to SSPC 10 (sand blasted) and spray coated with 4.0 mil DFT (dryfilm thickness) of Wearlon® 2020.90 Primer, room temperature cured for 24 hours, followed by spray coating with Wearlon® 2020.98 Top- Coating to 4.0 mil DFT. The coated panels were cured at room temperature (minimum 20° C) for 7 days before testing commenced. Exposure tests have been conducted for 50 days in accordance with a modified version of ASTM G20-88. Under certain corrosive conditions pigments might change color without affecting physical properties of the coating.
