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 scuff resistance and durability. Epoxy/graphite is commonly used as a bearing surface, as a coating on rudders and centerboards, or on the bottoms of racing craft that are dry sailed. It does not provide antifouling qualities.
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 color. Add to mixed resin/hardener at the rate of up to 10% by volume.
