UNISILKON L 641 is a special lubricating grease based on silicone oil and PTFE for valves and other elements in the heating, beverage and sanitary sector. UNISILKON L 641 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 641 allows constant actuating forces within the whole cold/hot water range of single-lever mixer taps. Due to its chemical composition, UNISILKON L 641 has shown to be resistant to various substances in the food-processing and beverage industries like beer, milk, juices, liquors, acid and alkaline disinfectants.
UNISILKON L 641 is not compatible with most organic solvents as well as acid and alkaline solutions.
Temperature range: -40°C to +160°C
Volume: 60g tube
Also available in: 500g can, 30kg bucket

UNISILKON L 641 is used as sealing and assembly aid for seals and packings in contact with water or water vapour, e.g.: domestic installations - ball valves; single-lever mixers – piston cartouches, ceramic discs; mixer taps with two handles – swivel spouts, shower switches, shower heads; thermostatic mixer taps – thermo regulators and elements; heating – thermostatic valves, tap cocks, pressfit seals; water hydraulics – sealing grease for radial shaft seals.

UNISILKON L 641 is neutral towards most metals, thermoplastics and elastomers.
Owing to the many different elastomer and plastic compositions their compatibility should be checked prior to series applications. UNISILKON L 641 can be applied by means of spatula, brush, usual metering devices or the tampon printing method.
