Japanese Kokubu Announces Natural Oil Based Coating for Stainless Steel Screws
Add to my favorite
The "KC18" coating announced by Kokubu Corporation is nothing like anyone would expect as it mainly consists of rice bran oil that enables acid resistance for the coating. Since ancient times, the Japanese has been using natural oils to prevent rust on swords and other iron objects.
Salt spray tests reveal that KC18 can resist red rust for 2016 hours. Cyclic tests show KC18 can prevent red rust for 16 cycles (16 hours of salt spray and 8 hours of drying). KC18 can not only be used as a lubricant in operation, but also improves thread fastening performance, while contributing to environmental protection.
