MOLYKOTE 3452 1 kg, chemical-resistant valve grease, NLGI 3, fluorosilicone, high-temperature
0
Description
MOLYKOTE 3452 Chemical Resistant Valve Grease 1 kg is a fluorosilicone lubricant and sealant for valves, engineered for corrosive environments and high temperatures. With an NLGI 3 consistency, it effectively lubricates and seals valves, shafts and packings, resisting water, fuels, oils and many solvents.
Benefits and unique features
- Outstanding chemical resistance – acids, chlorides, low-pressure steam and condensate
- Resists washout by water, fuels, oils and solvents
- NLGI 3 – sealing and lubricating action in valves and on shafts
- Compatible with many gaskets, seals and packings
- Wide service range up to 232 °C with low high-temperature losses
Properties and applications
- Valves and sealing: plug/globe valves, mechanical seals and packings, flexible ball joints.
- Bearings in harsh media: slow-speed roller and journal bearings, moderate-speed ball bearings.
- Instrumentation in vacuum, heat and corrosive atmospheres: rotary and reciprocating shaft seals.
- Limitations: not recommended with highly oxidative chemicals (e.g., liquid O2, liquid Cl2); soluble in ketones (acetone, MEK, MIBK).
