Corrocoat Biofoul

A three-pack, cold-cured polyester containing metallic (inorganic) copper flakes. Corrocoat Biofoul is considered non-toxic; it has excellent long-term anti-fouling properties and will  withstand flow velocities in excess of 25m/s.


Suggested use

Biofoul has been specially formulated as a durable, longlife, heavy duty, anti-fouling coating. It can be applied to metal over a corrosion barrier or it may be used in mould prior to the gel coating to give anti fouling protection to GRP structures. It may also be applied directly to GRP that has had suitable surface preparation. It can also be used to give the appearance of copper cladding to architectural features and exhibits the appearance of copper verdigris in service.


When applied to metallic substrates, this product should only be applied over a corrosion barrier of a Polyglass series or other Corrocoat material and over a suitably primed surface
on wood or concrete.


Health & safety

Before handling or using this product, first consult the material safety data sheet.


Surface preparation

On metallic surfaces, Corrocoat Biofoul should be applied over the top of a suitable corrosion barrier which has been correctly applied on a prepared substrate. Corrocoat Biofoul
can also be applied to GRP, concrete and wood with suitable surface preparation. For details, please consult Corrocoat Technical Services.

Application equipment

Preferably spray applied using airless equipment to obtain a smooth surface and optimum performance but may be applied by brush.

Mixing and application

Remove the lid from the paste container. Stir to mix the contents into a smooth even paste. The addition of 2% by volume of styrene added to the paste may aid this process but should not be used unless necessary. Add the contents of the resin container to the paste container. Using a mechanical agitator, mix thoroughly then immediately add the organic peroxide and agitate until thoroughly mixed. Apply the product immediately as pot life can be short at high ambient temperatures. Best results are obtained from a smooth surface. When applying by brush, light brushing with styrene immediately after application will aid smoothing. Do not pre-mix the resin and paste prior to addition of the catalyst, this will both shorten the pot life and storage stability.

Apply Biofoul at a thickness of 250-400 microns. Providing the maximum overcoating time of 3 days is not exceeded, Biofoul may be overcoated by itself. This period must be shortened at high temperatures and in strong UV light conditions.
