Hard or contact leaching antifouling paint dries to a hard but porous film that is packed with biocide. The biocide begins to leach out on contact with water to prevent fouling growth. This leaching is chemically designed to release biocide while the boat is in the water. Out of the water the paint film will oxidize and slow the release of the biocides to the point where there may not be enough biocide coming out of the paint film to maintain fouling protection. One of the main benefits of this type of antifouling is its resistance to abrasion and rubbing. This makes it ideal for fast powerboats, racing sailboats or boats where the owners have the bottoms scrubbed regularly. Hard antifoulings from Interlux® include Ultra, Ultra-Kote®, Fiberglass Bottomkote®, Fiberglass Bottomkote® Aqua, Super KL, Epoxycop, VC® Offshore and Baltoplate®
For boats that are going to be hauled and relaunched on a regular basis or hauled for seasonal storage consider using Micron antifouling paints. Micron antifouling paints can be hauled and relaunched without repainting since the biocides are chemically bound to the paint film and are only active when in the water. The longevity of these coatings is related to the thickness of the paint.
