Single-Component SPC Antifouling Paint
Self-Polishing Copolymers (SPC) technology antifoulings work because the film contains a patented resin called an 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 the boat is at sea or in port.
Single-Component CDC Antifouling Paint
Controlled Depletion Copolymers (CDC) are partially soluble which means that as water passes across the surface of the coating, it wears down much like a bar of soap. 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.
For this reason they have the capability to perform in areas of highest fouling.
Single-Component CL Antifouling Paint
The technical term for hard antifouling paints is Contact Leaching (CL). The paint dries to a porous film that is filled with biocides, which leach out on contact with water to prevent fouling growth. This leaching is chemically designed to release biocide along time. The amount will steadily decrease until film biocide depletion.
One of the main benefits of this type of antifouling is its resistance to abrasion.
Antifouling (or bottom) paint provides your vessel with a protective coating against vegetative growth.
Preventig fouling will improve vessel speed and efficiency, as fouling causes drag, which slows the ship down and increases fuel costs. Additionally, heavy fouling growth reduces the responsiveness of the ship. Finally, prolonged fouling growth will damage the substrate of the hull: the natural glues marine organisms use to attach could damage protective coatings.
