UCON™ UCONALL™ LUB 68 is an ISO 68 polypropylene glycol-based lubricant for extreme pressure environments.
UCON™ UCONALL™ LUB 68 is a high-performance extreme-pressure lubricant. UCONALL™ LUB 68 has been formulated to provide excellent lubrication, stability, and extended service life. Dow Chemical has worked to eliminate many of the problems commonly encountered with traditional petroleum-based lubricants. UCONALL™ LUB 68 is differentiated by viscosity which is 66 cSt at 100°F with a flash point of 530°F.
