LM 331 Contact-Grease

DESCRIPTION LM 331 Contact Grease is a grease-type, fully synthetic contact treatment preparation which is compatible with plastics and free of silicones. The special additives, synthetic oil and consistency modifiers in this product ensure that it can be used over a wide range of temperatures. The product shows no signs of chemical decomposition or resinifying even after long periods of use.-

PROPERTIES - very compatible with plastics
- stable to ageing, liquifying and oxidation
- reduces contact resistance
- suppresses arcing and wear
- penetrates layers of oxides and sulphides
- good mechanical lubrication properties
- high corrosion protection

APPLICATION LM 331 Contact Grease is mainly suitable for the maintenance and protection of all types of contacts in weak current engineering. This applies both to predominantly dormant contacts (such as plug connections and compensating controllers) and to moving contacts (such as switches, sliders, relays and wire-wound potentiometers etc.).

INSTRUCTIONS Before treating with LM 331 Contact Grease, the contact surfaces must be clean and free from residues such as lubricants, dirt and moisture. Apply the product as a thin, uniform layer.
