Molykote U-N Paste

A PAG-based anti-seize paste formulated with solid lubricants such as molybdenum disulfide and white solids.

Features & benefits

• Dry lubrication up to 450°C

Applications

For assembling, running-in and permanent lubrication of components that are subjected to high temperatures. MOLYKOTE® U-N Lubricant Paste is suitable for the dry lubrication of bearings (low rotary speeds), slideways and joints that are subjected to temperatures exceeding 200°C; at higher temperatures, the carrier volatilizes, leaving virtually no residue, and the remaining dry anti-friction film alone takes over the only lubrication up to +450°C – even beyond this in a protective gas atmosphere. As the paste has a synthetic oil base, it is also suitable for lubricating construction elements that consist of materials that are not resistant to mineral oils. Used successfully for roller and sliding bearings of foundry ladles and converter bearings in steel works, conveyor and driving rollers of belt conveyors, in the bearings of furnace and shuttle kilns, chains and chain conveyor rollers, for joints of ironing presses, for O-rings that are not resistant to mineral oils, lip seals, rubber and cup leathers.

Composition

• Technology: Polyalkylene Glycol (PAG)
• Thickener: Lithium
• Solid lubricants: MoS2, white solids

Available pack sizes

• 1 kg can - 10 per carton

About this type of lubricant

A paste is a very high concentration of solid lubricant in a small amount of carrier oil — closer to a thick suspension than to a grease. It is used where a grease would be squeezed out: assembly and running-in of tight metal-to-metal fits, press fits, splines, threaded fasteners and anti-seize duty. The solids stay behind on the surface after the carrier is gone, which is the point.

How to choose

Pastes are for assembly and slow, heavily loaded contact, not for continuous high-speed lubrication — use a grease for that. For threaded joints, the coefficient of friction is the number that matters, because it is what a torque figure assumes; a paste that changes friction changes the clamping force the bolt actually achieves. Copper- and metal-filled pastes should not be used on stainless or on joints where galvanic corrosion is a risk.

How to order

Specify the pack size and, where more than one grade shares a name, the exact grade on the RFQ. Indus Hydraulics is an authorised distributor and quotes MOLYKOTE® from Dubai stock where the grade is held; less common grades ship to order. Our engineers will confirm the grade against your application and operating conditions before you commit.
