Anti-fouling paint and foul-release propeller coatings are two different approaches to preventing fouling on boat propellers.
Anti-fouling Paint:

  1. Chemical Barrier: Anti-fouling paint contains toxic chemicals (biocides) that does deter the growth of marine organisms like barnacles, algae, and mollusks on the bottom of a boat. It works by creating a chemical barrier on the surface. It is not a practical solution for boat propellers and running gear as it will quickly come off your propeller when used.
  2. Erosion and Leaching: Over time, the biocides in anti-fouling paint slowly erode or leach out of the coating, releasing the chemicals into the water to deter fouling. This process provides long-lasting protection but may require periodic reapplication.
  3. Effective in Various Conditions: Anti-fouling paint is effective in various water conditions, including salt and freshwater. It is commonly used in marine environments where fouling is a concern.
  4. Maintenance: Regular maintenance, such as cleaning and occasional recoating, is necessary to ensure the continued effectiveness of anti-fouling paint.

PropGlide® Foul-Release Propeller Coatings:

  1. Non-Toxic: PropGlide® foul release coatings are non-toxic and do not rely on toxic chemicals to prevent fouling. Instead, they create a low-friction surface that makes it difficult for marine organisms to attach to the propeller while in use.
  2. Low Friction: PropGlide® coatings create a super-smooth surface that reduces drag, allowing the propeller to operate more efficiently and improve fuel efficiency.
  3. Easy Cleaning: Fouling organisms that do attach to the coated surface can be more easily removed through the motion of the boat. This reduces the need for frequent maintenance and recoating.
  4. Environmental Considerations: PropGlide® foul-release coatings are environmentally friendly because they do not release harmful chemicals into the water.
  5. Durability: PropGlide® foul-release coatings can provide effective fouling protection for a reasonable period (usually as long as the bottom paint), depending on the specific usage conditions.

In summary, the main difference between anti-fouling paint and PropGlide® foul-release propeller coatings is their effectiveness in preventing fouling. Anti-fouling paint uses toxic chemicals to deter fouling. It will not last on your propeller, while PropGlide® foul release coatings create a non-toxic, super slick surface that marine growth cannot adhere to while maintaining better adhesion to underwater metal surfaces, including the propellers and running gear.
