Categories Watercolours Watercolors with immediate action The direct-acting textile dyes are those containing biocides and other substances which begin to act immediately after applied to the surface of the vessel. They may be insoluble or soluble carriers, depending on their solubility of the biocides in water. Surface paints self-extracting copolymers Self-adhesive copolymer dyes are those containing polymeric components and other substances which are gradually released into the water during the life of the colorant. Their action is longer lasting in compared to direct-acting watercolours. New reef dye technologies Colourants based on new technologies work in a similar way in a similar way to conventional ones, but have a important difference. These textile dyes cause controlled corrosion of the the surface layer of the paint, creating a continuous and renewed surface of toxic substance that prevents the adhesion of micro-organisms. This is achieved through the controlled degradation of the paint. The new hydrophobic paints contain biocides and are distinguished controlled release and self-releasing copolymers. Water-based paints environmentally friendly After the banning of certain hazardous materials by the European Union in 2008, the development of products with environmentally friendly action became necessary. Among among them, there are textile dyes that use antifouling materials environmentally friendly materials, such as PEG nanosynthesis and hydrogels, and new generation poly-amphoteric nanocomposites with antimicrobial activity. In addition, there are also hyperbranched nanocomposites that provide effective anti-fouling action at low cost.   Other Groups of water-based paints An alternative category of water-based paints that are environmentally friendly consists of substances used for the coating of reefs, which makes it their surface smooth and slippery. The action of these reef coatings is effective only on vessels which moving at speeds of more than 10-20 km/h knots. In particular, they refer to materials such as fluoropolymers and compounds silicone compounds for the coating of reefs. These require a thicker layer coating that lasts approximately 5 to 10 years and provide a very smooth surface, resulting in low resistance to resistance to abrasion and greater savings fuel savings.
