Cerakote Gun Coatings Corrosion 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 the an enclosed salt spray chamber at 15-30 Degree angle and subjected to a continuous indirect spray of neutral (Ph6.5-7.5) 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 gun coating H-146 Graphite black panels were checked for corrosion at specific intervals of 45,160,255,385,675,850,1000,2000,3000 and 3500 hours. At 3500 hours Cerakote H-146 was not corroded. this study shows that Cerakote Preserves the life of the firearm in a corrosive environment longer than any competitive coatings.
