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. The grease is compatible with most substances in the foodprocessing 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.
UNISILKON L 641 is NSF H1 registered and therefore complies
with FDA 21 CFR § 178.3570. The lubricant was developed for
incidental contact with products and packaging materials in the
food-processing, cosmetics, pharmaceutical or animal feed
industries. The use of UNISILKON L 641 can contribute to
increase reliability of your production processes. We nevertheless
recommend conducting an additional risk analysis, e.g. HACCP
Application :
UNISILKON L 641 is used as sealing and assembly aid for seals
and packings in contact with hot and cold water or steam, 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.
