Fuchs Molypaul PBC (Polybutylcuprysil) Anti-Seize Compound

PBC is suitable for use as a non-melt extreme pressure lubricant between slow moving surfaces and as a grease at temperatures up to 150°C. Above these temperatures and at temperatures up to 1200°C PBC forms oxide compounds that are effective as parting agents.

Applications: Threaded Fastenings:PBC is a torque equalisation compound and anti-seize, for pre-stressed bolts, studs and threaded components. The co-efficient of friction is typically 0.1 @ 20°C. Independent testing is recommended. Plain Bearings, Pivots, Trips Slow Moving Mating Surface :PBC is a protective grease that acts as a lubricating seal to prevent the ingress of water and corrosive solutions. It may also be used as a jointing compound on the joint faces of covers and gaskets. Mating Surfaces: PBC is an anti-fretting medium where relative movement between plain bearing surfaces is of a low magnitude.

Examples of such conditions are found on: Plain Bearings Splined Shafts (Vibration high temperatures) : internal surfaces of cement kiln live rings braking mechanisms bearing sleeves/rings and housings splined shafts and serrations geared / toothed couplings. Roller Bearings (oscillating) :PBC acts as an anti-fretting medium in rolling element bearings subjected to vibration and small oscillating movements. Such bearings are found in variable pitch blade fans, universal joints / cardan shafts, and the thrust bearings of heavy vehicles.

The bearing housings must be completely filled with PBC Roller Bearings (rotating) :PBC is designed for use as a protective high temperature non-drip/non-melt lubricant for re-greasable conveyor trolley wheel bearings and chain rollers with re-greasable rolling bearings. It can be safely used in conveyor bearings operating over plants and has no deleterious effect on either hot or low temperature acid phosphate solutions.
