Test: ASTM B117
Salt Spray (ASTM B117) Corrosion testing is used to evaluate the relative corrosion resistance of coated panels exposed to a salt spray or fog at an elevated temperature. Coated panels are placed in an enclosed salt spray chamber at a 15-30 degree angle and subjected to a continuous indirect spray of a neutral (ph 6.5-7.2) salt water solution. The chamber/cabinet is kept at an operating temperature of 95F and fogging a 5% salt solution at the required 12ml/hr. Cerakote MC-160 and H-300 panels were checked for corrosion at specific hourly intervals. Cerakote MC-160 began to show signs of corrosion after 69 hours in the salt chamber, and Cerakote H-300 began to show signs of corrosion after 317 hours. This study shows that Cerakote Clear Coatings preserve the life of a coated object in a corrosive environment longer than any competitive coatings.
