425 Copper compound

425 Copper compound can be added to mixed epoxy to provide a hard base coat for the conventional bottom paint used on boats. When added to the epoxy at the rate of 80% by weight, the resultant hard surface increases the moisture exclusion effectiveness, abrasion resistance and provides some back-up antifouling properties. It can also be used for any coating application when a harder surface is required. A good application of this is in the construction of large moulds.
