423 Graphite Powder is a fine black powder that can be mixed with West System epoxy to produce a low-friction exterior coating with increased scruff resistance and durability. Epoxy/graphite is a commonly used low-load, low-speed bearing surface, and as a coating on rudders and centreboards, or on the bottom of racing craft that are dry sailed. It does not provide antifouling properties. The epoxy/graphite mixture can also be used in teak deck construction to simulate the look of traditional seams and to protect the epoxy from sunlight. Cures to a black colour.
