Abstract
Multi-layer anti-fouling coatings include a first biocidal layer formed on a surface. The first biocidal layer includes at least one biocidal biocide that kills a biofouling organism on contact with the first biocidal layer. A first biostatic layer is formed between the first biocidal layer and an external environment. The first biostatic layer includes at least one biostatic biocide that inhibits a biofouling organism from attaching to the first biostatic layer.
Claims16
A multi-layer anti-fouling coating comprising:
- a first biocidal layer formed on a surface, the first biocidal layer comprising at least one biocidal biocide that kills biofouling organisms on contact with the first biocidal layer;
- and
- a first biostatic layer formed between the first biocidal layer and an external environment, the first biostatic layer comprising at least one biostatic biocide that inhibits biofouling organisms from attaching to the first biostatic layer and does not kill biofouling organisms on contact with the first biostatic layer, wherein the first biocidal layer further comprises the at least one biostatic biocide and the first biostatic layer further comprises the at least one biocidal biocide, wherein the concentration of the at least one biocidal biocide in the first biocidal layer is higher than the concentration of the at least one biocidal biocide in the first biostatic layer, and wherein the concentration of the at least one biostatic biocide in the first biostatic layer is higher than the concentration of the at least one biostatic biocide in the first biocidal layer.
