Salt spray test cleared for 5000 hours! Introducing the highly corrosion-resistant D-LOCK with a unique top coating added to the molten zinc-tin alloy plating!
"TONEJI SUPER COAT" The high corrosion-resistant D-LOCK, featuring a unique top coating added to a molten zinc-tin alloy coating, has been introduced. We conducted a 5,000-hour salt spray test (JIS Z 2371) assuming use in salt damage areas, and no red rust was observed, while the occurrence of white rust was minimized. Additionally, we performed a more rigorous CASS test (ASTM B368-21) for 625 hours. Please make use of this for rust prevention measures in heavy salt damage areas. ◎ For more details, please refer to the PDF document or feel free to contact us.
