Salt spray test passed 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, enhanced with a unique top coating on a molten zinc-tin alloy plating, has arrived. 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 CASS test (ASTM B368-21) for 625 hours as an even more rigorous examination. 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.
