423 Graphite Powder

423 Graphite Powder is a fine black powder that can be mixed with epoxy to produce a low-friction exterior coating with increased scuff resistance and durability. Epoxy/graphite is commonly used as a low-load, low-speed bearing surface, as a coating on rudders and centreboards, or on the bottoms of racing craft that are dry sailed. It does not provide antifouling qualities. Add to any mixed WEST SYSTEM 105/200 Series Hardener combination.

  • Low-Friction Coating

Modifying with fillers and additives makes WEST SYSTEM epoxy extremely versatile for a wide variety of bonding and coating applications. Epoxy can be thickened to the ideal consistency needed for a particular job. Epoxy thickened with adhesive (high-density) fillers strengthens structural bonds, bridges gaps, and fills voids. Epoxy thickened with fairing (low-density) fillers is easily sanded and shaped after it cures.
