Corrocoat is our main range of corrosion protection coatings.
Corrocoat anti-corrosion paint is ideal for critical service applications, these high-performance polymeric products offer long-term prevention of biofouling, resistance to cathodic disbonding, crack bridging, high conductivity, and resistance to chemicals, including high concentrations of sulphuric acid.
Biofoul has been specially formulated as a durable, long-life, 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.
Before handling or using this product, first consult the material safety data sheet.
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.
Preferably spray applied using airless equipment to obtain a smooth surface and optimum performance but may be applied by brush.
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.

It is strongly recommended that de-humidification equipment is used during the application of this product.
Before handling or using this product it is important that the material safety data sheet is read and all precautions observed. Attention is drawn to Hardener B which contains Isocyanates.
XT Veilcoat is applied over Corrothane XT whilst still tacky or before the maximum overcoating period has expired.
45:1 or greater airless spray pump, with an output of at least 4 litres per minute. Spray tip and fan pattern can vary and should be selected to suit the nature of the work. XT Veilcoat
can be applied by brush or roller in areas of limited access but not generally recommended.
Due to the hydroscopic nature of this product, the Base and Hardener B should be kept sealed until required. It is recommended that kit sizes are ordered to allow complete use of the product during each application to prevent moisture absorption when using part tins. Dependent upon end use and application conditions, Corrothane XT is normally applied in wet film thickness of
between 200 and 375 microns.
By Weight:
87.83 parts Base
01.57 parts Hardener A (organic peroxide)
10.60 parts Hardener B (Isocyanate)
Mix the base with a mechanical stirrer until it is uniformly mixed. Add Hardener A (organic peroxide) to the Base and mix thoroughly, allow to stand for 10 minutes. Thoroughly stir the Base/peroxide blend again and leave to stand for a further 5 minutes (NB. The Base/peroxide blend is relatively stable and will not react significantly until the Hardener B is added). Add Hardener B (Isocyanate) and mix thoroughly before applying.
Corrocoat EC is the surface veil coating for use with Corrocoat EB and Corrocoat EA. The coating possesses good chemical resistance and when applied to a thickness over 1.5mm good cavitation resistance.
This material should not be applied at temperatures below 5°C. Thixotropic properties are such that multiple coats will be required to achieve thicknesses over 300mm. Keep overcoating times short.
Health and Safety information should be read and observed before handling this material. Avoid contact with skin or eyes. Do not ingest. Wear protective clothing and goggles. Ventilate
confined spaces. The base and activator materials are not particularly hazardous and are safe to use provided good hygiene and working practices are followed.
For optimum performance under immersed conditions this product should be applied to surfaces, grit blasted to ISO 8501-1 SA 2½ or equivalent. For full details refer to Corrocoat Surface Preparation SP1 or SP2.
Brush or air assisted spray gun and pressure pot.
Apply at approximately 300 microns DFT over the E series material, or in multiple coats to achieve the required thickness.

As this product contains no solvent, minimum overcoating time is not important except in avoiding disruption and drag of the previous coating. Short overcoating times as opposed to long overcoating times, are recommended for optimum intercoat adhesion properties. In order to check that surface drag is not likely to occur, a finger or thumb can be used, to pull the surface
and where movement is observed, a longer period should be allowed before overcoating. As a guide only, the minimum overcoating times will generally be as follows:
It is essential, to achieve intercoat adhesion, the maximum overcoating time is strictly adhered to. The maximum overcoating times are as follows:
In order to achieve the full properties of this material a period of 3 days at 20°C in ventilated conditions, should be allowed before service. Where chemical or erosive forces are likely to be encountered a period of 7 days should be allowed. However, due to the cure action of this product, the coating can be put to light aqueous service as soon as the product has gelled. This should generally be in accordance with the minimum overcoating time. Product will then continue to cure in service.
7 days at 20°C or 4 days at 30°C
NOTE: Cure below 10°C will be slow, exposure to higher temperatures (15°C-35°C) will improve the rapidity and degree of cure achieved. High humidity will extend cure times. Thinners
The product should not require thinning. The use of solvent thinners can lead to solvent entrapment in the film, which will adversely affect performance.
A blend of xylene/n-Butanol at 4:1 v/v may be used.
Alternatively, any proprietary epoxy clean-up solvent may be used.
