SINOPEC Premium Golden Grease, NanoShield is a multi-purpose grease derived from advanced nanotechnology. It is prepared through the saponification of high-activity Nano-precursors and special fatty acid that forms compact and stable metal soap fibers in high quality mineral base oil. Due to special properties of nanoparticles, SINOPEC premium golden grease, nanosield can provide excellent anti-wear protection, superior lubricity, as well as outstanding mechanical stability, water resistance, adhesion, sealing and rust resistance.
Technical Features
· Excellent lubricity to reduce abrasion between friction pairs.
· Excellent resistance to water washout, improved lubricity even under conditions such as high ambient humidity and inevitable contamination with water.
· Outstanding oxidation stability to ensure longer service life during application process.
· Outstanding mechanical stability under harsh shearing forces.
· Superior rust resistance capability to prevent wear of the friction pairs during the operation.
· Good adhesiveness within the applicable temperature range.
Applications
· Suitable for the lubrication and the protection of low speed equipment such as con- struction machinery, agricultural machinery, ceramics (such as polishing machines, transmission bearings) , metallurgy (such as conveying roller table) , automobile
(chassis, wheel hub) and conventional general machinery, etc.
· Application where the temperature range is from -20ºC~120ºC.
