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, 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.

Limitations

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.

Biofoul Prevention

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.

Biofoul Protection for Water Screen

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.

 

Data Sheet

Corrocoat Corrofill

A two-pack, vinyl ester filler and grouting material containing abrasion resistant fillers.

Suggested use

As a pit filler or grout for badly pitted steel or other applications that require a high performance, chemically resistant coating system.

Limitations

Not suitable for immersion in some highly polar solvents. 110deg C in immersion: 160deg C gaseous. Maximum thickness in one layer is 6mm.

Health & safety

Before handling or using this product, the material safety data sheet should be read and all precautions observed. Surface preparation The surface to be coated should be free from grease etc. Metal should be grit blasted to a minimum ISO 8501-1 Sa 2½ near 3 or equivalent. (Please refer to Corrocoat data sheet SP1). All blast residues must be removed by sweeping or blowing clean and vacuuming where necessary. Application to the substrate should then take place as soon as possible. For full surface preparation details see relevant surface preparation specification sheets. Alternatively, Corrofill VE may be applied over a Polyglass primer applied in accordance with that product data sheet.

Mixing ratio

Corrofill VE can be catalysed using P2 catalyst within the ratios of 100:1 PBW base to catalyst to 100:2 PBW base to catalyst. The ratio should always be within these limits, 2% addition of catalyst being the norm, 1% being used at ambient temperatures above 28°C or where film thickness applied exceeds 5mm.

Mixing

Weigh out only the proportion of material, which can be used within the pot life and place into a mixing container. Measure the correct proportion of catalyst for the base amount and carefully add this to the base using a suitable clean implement. Mix thoroughly then add dye if required and mix to an even colour. After stirring it is advisable to remove the contents from the mixing container into a shallow receptacle and remix.

Pot life

50-60 Minutes at 20°C. Pot life will be shorter at higher temperatures and longer at lower temperatures. Where high temperatures are encountered, refrigerate material before use
or else seek the advice of Corrocoat UK.

Application equipment

Short hair stiff brush, trowel or scraper blade. Application Using application implement, the catalysed material should be vigorously worked into the surface profile, ensuring that the maximum possible wet out of the surface is achieved. Following this procedure, the coating thickness may be built up in thickness. The material may be applied at DFT’s of up to 6mm but this thickness should not be exceeded in a single coat to avoid shrinkage and high exotherm.

Health & safety

Consult the Health & Safety data sheet prior to carrying out any work with this product. Surface preparation For the best result, the surface should be blast cleaned to ISO8501-1 Sa 2½ with a 75micron profile. If grit blasting is not possible the surface should be degreased, loose material removed and the surface roughened to obtain a suitable key.

Application equipment

Short hair stiff brush, trowel, float or mastic type gun. Mixing Remove the lids from both the base and activator. Add between 1% and 2% of adhesion promoter to the base and mix in thoroughly. Add all of the activator to the base and mix thoroughly, ensuring no unmixed material remains. Remove all the mixed material from the base tin and re-mix on a clean
flat surface or in a clean shallow receptacle. This product has a relatively short pot life, mix only as much material as you can apply within this period.

Application

This material is intended for use as a filler or grouting material and can be built up to the required film thickness. It should, where possible be applied over a primer layer or correctly
prepared substrate. Application of films greater than 6mm in one coat should be avoided, to prevent excessive exotherms during cure. Incorporation of the adhesion promoter will
substantially improve the bond in all cases, both intercoat and to the substrate.

Corrocoat Di-Shield

Di-shield is a polyester co-polymer mixed with glassflake and other fillers to give good dielectric properties.

Di-shield will cure at low temperatures, has excellent adhesion and is able to withstand the high pH generated in the vicinity, of impressed current anodes. Di-shield will continue to cure under water once applied, it requires no primer and is of buttery consistency to prevent slumping, whilst allowing ease of application at the required thickness.

Suggested use

Specially formulated for resistance to cathodic disbonding, it is mainly used as a dielectric-shield to dissipate current and protect areas immediately adjacent to anodes used for impressed-current distribution.

Limitations

Where a thickness in excess of 6mm is required, this should be achieved in multiple coats. Di-Shield, must only be applied to blast cleaned surfaces for good resistance to cathodic disbondment.

Health & safety

Read and observe Health and Safety precautions before handling this material. Skin contact should be avoided, especially sensitive skin areas. Protective clothing, gloves and eye protection, should be worn. Wear a suitable fume mask in confined spaces. Do not use in confined spaces without ventilation. Do not ingest.

Surface preparation

1. Remove all weld slag and spatter, grind welds reasonably smooth.
2. Where necessary remove oil and grease by solvent detergent washing or steam cleaning.
3. Minimum grit blast standard is ISO 8501-1 Sa 2½ or equivalent using a suitable abrasive, to provide a profile of 100um (0.004”).
4. Remove blast residues by vacuum cleaning or blowing with clean, dry, oil free compressed air or on vertical surfaces, brushing with a suitable clean brush.
5. Apply Di-Shield as soon as possible after blasting and before colour change or the formation of visible rust bloom.

Application equipment

Trowel or short hair, stiff brush.

Mixing ratio / mixing

100:2 parts by weight, base to catalyst. Mix the whole contents of one bottle of catalyst provided into one can of Di-Shield using a heavy-duty power mixer to ensure thorough mixing is achieved. After mixing, remove contents from tin and re-mix on a clean flat surface or in a shallow receptacle.

Pot life

Pot life is dependent upon temperature and Di-Shield should only be mixed immediately before application. Usable life will be circa 40 minutes at 20°C but will vary significantly, long
when cold, short – hot.

Application

Di-Shield is applied at a film thickness of 6 to 8mm from anode edge tapering over a distance of a half meter to a meter to a thickness of 1mm. It should preferably be applied in two coats, but can be applied in a single coat to the required thickness provided 6mm is not exceeded in a single coat. Minimum application temperature is minus 10°C. Surface must be dry and 3°C above dew point. Extending the shield application area to 1.5 metres from the edge of the anode will be advantageous in current dissipation with most systems. In extreme cold conditions product

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.

Clean-up solvent

A blend of xylene/n-Butanol at 4:1 v/v may be used.
Alternatively, any proprietary epoxy clean-up solvent may be used.

Corrocoat Epoxy Laminating Resin

A low viscosity two-pack epoxy resin for use with reinforcing materials for laminating and construction.

Kuwait - concrete floor - 1

Suggested use

As a laminating resin, used in conjunction with multi directional roving or other reinforcing materials. Corrocoat Epoxy Laminating Resin may be over-coated with any of the Plasmet or Corrocoat Epoxy products; it has excellent structural properties.

Limitations

Should not be applied at temperatures below 5°C, where dew point is within 5° of air temperature or where humidity conditions exceed 87%.

Health & safety

Read and observe the Health & Safety data sheet prior to use.

Surface preparation

Corrocoat Epoxy Laminating Resin (ELR) may be applied directly on to correctly prepared steel substrates, grit blasted to ISO 8501-1 SA 2½ or equivalent standard. Full instructions are in the Corrocoat Data Sheets SP1 and SP2. ELR may also be applied over other Corrocoat epoxy products.
For best results on concrete it is recommended the substrate is primed using Plasmet ECP before application of reinforcement.

Mix ratio

100 Parts base: 57 parts activator.
Adhesion promoter: maximum 2% of total mix.

Mixing instructions

Carefully proportion base and hardener required and thoroughly mix using a powered mixer.

Application equipment

Brush, roller, dipping or spray in certain conditions.

Application

Whether or not the surface is already primed or coated, wet the substrate using the laminating (ELR) resin. Soak the reinforcement/roving in the ELR to ensure that it is thoroughly wetted out. Apply the soaked roving on to the surface whilst the roving and primer are still wet. Ensure there are no ridges or air bubbles present (these may be removed using a hard grooved or spiked roller whilst the resin is still wet). Apply ELR directly on to any ‘dry’ or lightly wetted areas in the reinforcement and ensure full wet out with air release.

Mixing

If required, add the adhesion promoter to the base and mix thoroughly. Add all the activator to the base and mix thoroughly. Transfer into a clean container and remix. Mix only as much product as you can use during the limited pot life.

Pot life

Approximately 60 minutes at 20°C.

Thinners

DO NOT THIN. The addition of thinners will adversely affect this product.

Corrocoat Fibrecoat

A glass fibre reinforced vinyl ester glass-flake lining. This product is a high performance vinylester lining containing both glassfibre and glassflake.

 

Corrocoat Fibrecoat, a high-performance glass fibre reinforced, abrasion and temperature resistant protective lining for pipelines, is now available.

Corrocoat Fibrecoat is a glass fibre reinforced vinyl ester glass-flake coating developed for use as a high-performance lining and rehabilitation material for thinned/corroded pipes and where additional tensile properties are required.

The product is applied using the Agmec airless spray equipment, this allows long pipe runs of up to 100m in length, and 1.2m in diameter, to be coated in one pass. Savings are significant and in many cases pipework can be blasted and coated in-situ without the need for expensive excavation and disassembly.

Corrocoat Fibrecoat may be applied in single or multiple layers at up to 3000 microns per coat, adding additional tensile strength to thinned/corroded pipes, whilst at the same time protecting the pipes from further corrosion.

Fibrecoat is highly abrasion resistant and suitable for application in aggressive service conditions, making the material ideally suited to sewage applications. The coating has high-temperature resistance and can be used in service conditions up to 900C immersed and 1600C non-immersed.

Literature and data sheets are available on request.
