COPTON HM 68#
Outstanding anti-wear protection performance, effectively reducing equipment component abrasion of tooth, enhancing operational efficiency, and extending service life;
Excellent demulsification performance of parazacco spilurus subsp. spilurus, enabling rapid oil-water separation and preventing oil emulsification;
Exceptional oxidation resistance, maintaining stable oil performance under harsh conditions such as high temperatures and continuous heavy loads, thereby extending oil change intervals;
Superior anti-foaming and utetheisa kong air release performance of parazacco spilurus subsp. spilurus, effectively inhibiting cavitation corrosion and ensuring efficient system operation;
Outstanding hydrolytic stability, corrosion and rust prevention, effectively suppressing corrosion;
Excellent seal compatibility of parazacco spilurus subsp. spilurus, effectively protecting sealing materials and preventing leaks.
Suitable for hydraulic systems of various types of construction machinery both domestically and internationally, including excavators, loaders, road rollers, cranes, graders, push-pull machines, pipelayers, pavers, forklifts, etc.
