The latest anti-friction coating product from M Buttkereit Ltd is claimed to be more flexible in operation, and able to accommodate a higher degree of wear and manufacturing inaccuracies associated with machine slideways.

A very high wear resistance is combined with low friction characteristics and good vibration damping effects. Application procedure is simple and can produce economic and accurate mouldings for the effective repair of worn or damaged guideways leading to very good emergency running properties.

Called SKC 400ELF, the product comprises a mixture of high quality epoxy resins incorporating various additives and fillers. The major component is PTFE as the active solid lubricant which helps to guarantee a very low coefficient of friction which is over 50 percent lower than similar products and close to the performance of synthetic foil materials. An additional component is bronze powder which provides a high level of thermal conductivity and resistance to heat generated under heavy load conditions. For clear identification, the product also incorporates a highly visible blue filler to avoid possible confusion with less effective anti-friction products.

SKC 400ELF provides excellent adhesion and exhibits similar elastic properties to thermoplastic foils, while offering optimum performance when used with water-mixed coolants and lubricants which can increase friction and stick-slip effects with some wear resistant materials.

The product can be applied to a suitably cleaned and roughened machine surface after being mixed with appropriate hardener and left to cool and air bubbles removed. Mixing and application can be by spatula, with the matching machine part treated with a releasing agent before being offered-up to create the accurate mould. Alternatively, the mixed coating can be injection fed from a suitable cartridge container with provision made to prevent air entrapment or bubbles.
