UNISILKON L 643 is a special lubricating grease based on silicone oil and PTFE for valves and other elements in the sanitary and heating sector. It offers good penetration ability in small lubrication gaps and lube points of difficult access. As its viscosity is rather independent from service temperatures, UNISILKON L 643 allows constant actuating forces within the whole cold/hot water range of single-lever mixer taps. The grease is resistant to many aqueous solutions as well as acid and alkaline disinfectants. It is not compatible with most organic solvents, strong acid and alkaline solutions.
