Contributing to cost reduction! We introduce our gas corrosion prevention solutions for products.
"Ep Coat" is a surface treatment designed to combat sulfur dioxide gas, featuring a three-layer structure. Sulfur dioxide gas is a gas that has a pungent odor. It is found in emissions from industrial areas and in gases generated in hot spring regions, and it can promote metal corrosion, among other effects. This product has gas resistance and is effective against sulfur dioxide gas. The synergistic effect of the three-layer structure provides powerful overall corrosion resistance. 【Features】 ■ Gas Resistance - Effective against sulfur dioxide gas - Resistant to sulfur dioxide ■ Corrosion Resistance - Salt spray test (JIS Z 2371) shows over 1000 hours of red rust - Composite cycle test (JASO M609-91) shows over 100 cycles of red rust occurrence ■ Chemical Resistance - Passes immersion tests for acid resistance (0.1N sulfuric acid, hydrochloric acid), alkali resistance (0.1N sodium hydroxide, etc.), and oil resistance (gasoline, etc.) *For more details, please refer to the PDF document or feel free to contact us.
