DIFFERENT TYPES OF ANTIFOULING PAINTS
SPC technology antifoulings work because the film contains a patented resin called "SPC Copolymer". This copolymer reacts with saltwater in a controlled way. As a result, the chemical reactions controls and sustains the release of biocides throughout the lifetime of the antifouling without decline. This chemical reaction will take place at the same rate whether you boat is underway or sitting at the dock. This type of technology has previously only been available in tin-based copolymer coatings, which are restricted in their use to boats over 82 feet in length. This new, patented Interlux technology is available for professional application to boats of all sizes. It is not recommended for use in fresh water.
For Self-Polishing Copolymers ask for Micron 66
CONTROLLED SOLUBILITY COPOLYMERS
These types of antifoulings are partially soluble which means that as water passes across the surface of the coating, it wears down much like a bar of soap would wear away. The physical action of the water over the surface steadily reduces the thickness of the paint at a controlled rate, which results in always having fresh biocide at the surface of the paint throughout the season. For this reason these types of antifoulings have the capability to perform in the areas of highest fouling challenge. Since the biocides are chemically bound to Controlled Solubility Copolymers they can be hauled and relaunched without repainting as the longevity these coatings are related to the thickness of the paint.
For Controlled Solubility Copolymer Antifoulings ask for Micron Extra with Biolux or Micron CSC.
Ablative Antifoulings wear away with use like the controlled depletion polymers but at a much less controlled rate. Ablative antifoulings are affected more by water temperature., salinity and alkalinity than are the controlled depletion polymers and generally wear away faster. They are less expensive than controlled depletion polymers and they provide excellent antifouling protection but they don't last as long as the controlled depletion polymers or controlled solubility copolymers.
For ablative Antifoulings ask for Fiberglass Bottomkote® ACT.
The technical term for these types of antifouling paints is 'contact leaching'. The paint dries to a porous film that is packed with biocides, which leach out on contact with water to prevent fouling growth. This leaching is chemically designed to release biocide throughout the season, but the amount will steadily decrease until there is not enough biocide coming out of the paint film to maintain fouling protection. Once the biocide is exhausted, the hard paint film remains on the boat. Hard antifoulings do not retain their antifouling ability out of the water and cannot be hauled and relaunched without repainting. 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. Most hard antifouling paints can be wet sanded and burnished prior to launch to reduce drag and improve hull speed.
For Hard Antifoulings, ask for Ultra (TM) with Biolux or Fiberglass Bottomkote. For Hard Racing Finishes, ask for VC Offshore with Teflon, Baltoplate, or VC 17m
