Marine coating formulations

A formulation comprising:

• (a) a nano-active material comprising a powder material with an average particle size in the range of 1-300 microns, with a volumetric pore surface area greater than 100 m2/cm3;
• and
• (b) a polymer binder;
• and
• (c) additives comprising pigments, booster antifoulants, booster anticorrosion materials, solvents, polymerisation activators, viscosity modifiers and fillers;
• wherein the booster anticorrosion materials comprise lanthanide material;
• wherein the mixture of the nano-active material, the binder and the additives provides an antifouling and anticorrosion coating to maritime infrastructure or vessels, when applied.
