Bund Coat 3
CPR 614 – Bund Coat 3 is a rapid curing, two pack, solvent free Epoxy coating with outstanding resistance to aggressive acids, solvents and alcohols, e.g. 96-99% Sulphuric Acid, Methyl Ethyl Ketone and Methanol.
- Solvent free
- Outstanding chemical resistance
- Excellent adhesion to concrete and steel
- Tough, durable and abrasion resistant
- Very rapid cure, even at low temperatures
- Hygienic and easily cleaned
- Slip resistant options
Directions for Use
- Concrete shall be a minimum of 21 days old and/or the residual moisture content shall be below 6%. Ensure that the concrete is clean and free from dust, laitance, grease, oil, curing compound and existing paint finishes etc. Blow holes and defective concrete shall be made good using a proprietary repair compound e.g. CPR 719 – Epoxy Concrete Patch Repair Mortar or CPR 726 – Concrete Re-surfacer. Suitable mechanical treatment such as vacuum grit blasting is the preferred treatment prior to application as this ensures a mechanical ‘key’ for the coating.
- Steel surfaces shall be shot blasted or grit blasted to a nominal Sa 2.5 Swedish standard. All dust and grease shall be removed prior to coating application. If a delay is likely to occur between
blasting and application then it is recommended that a coat of CPR 410 – Metal Primer – Epoxy WB is applied as holding primer to obviate flash rusting.
- A coat of CPR 401 – Concrete Primer – Epoxy WB is recommended on absorbent concrete surfaces (apply in accordance with CPR 401 – Concrete Primer – Epoxy WB data sheet).
- For steel substrates CPR 614 – Bund Coat 3 may be applied directly (see also surface preparation advice)
- Pour the contents of the CURING AGENT container into the BASE container and thoroughly mix, preferably by mechanical means until a uniform colour is achieved.
- Apply by brush, short pile roller or airless spray at a nominal rate of 0.3 to 0.5kg/m² per coat, depending on overall dry film thickness required.
- After a minimum of 6 hours @ 20°C but within a maximum of 24 hours, apply a second coat at the same nominal rate.
- If the maximum overcoating limit is exceeded, the first coat must be abraded and solvent wiped prior to application of the second coat.
- Should a non-slip finish be required, then a broadcast of graded Quartz or Aluminium Oxide shall be made immediately after the first coat.
- Brush off excess aggregate prior to application of the second coat.
- Clean equipment with CPR 201 – Tool Clean Solvent prior to curing of the coating.
- Allow to cure for a minimum of 6 hours @ 20°C prior to light foot traffic access and 24 hours @ 20° prior to vehicular trafficking.
- Allow a minimum of 5 days cure @ 20°C for optimum chemical resistance.
Storage and Shelf Life
- Store in dry conditions, out of direct sunlight, at temperatures between 10°C and 25°C.
- CPR 614 – Bund Coat 3 has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions.
- CPR 614 – Bund Coat 3 is supplied in 5kg and 15kg packs.
- A 5kg pack is sufficient to treat 8.3m2 of surface with the recommended two coat treatment, providing an overall d.f.t. of 500 microns.
- Pot life @ 20C: 30 Minutes/ @ 10C: 60 Minutes
- Colours: Grey, Red (BS4800 or RAL colours on request)
- Coverage: 0.25-0.30kg/m²/coat
- Tack free time @ 20°C: 3 hours
- Hard dry time@ 20°C: 6 hours
- Full chemical resistance @ 20°C: 5 days
- Adhesive strength to concrete: 4.4MPa (concrete failure)
- Adhesion strength to Sa 2.5 steel: 14 MPa
- Temperature range during application: 2°C to 30°C
- Temperature range in service: -20°C to 70°C
- Please consult our Technical Team for specific advice.
- Do not apply to wet or uncured concrete surfaces.
- Do not apply at temperatures of 2°C or less.
- Discoloration/bleaching of the coating can occur on contact with certain aggressive chemicals, thus leading to contamination/discoloration of the chemical itself.
- A clear coat of CPR 603 – Acid Resistant Epoxy Laminating Resin is therefore recommended where chemical storage tanks are involved.
- Discoloration is purely a surface effect that does not detract from the efficacy of the coating in service.
Health and Safety
- Avoid contact of the material with skin and eyes.
- Wear gloves and goggles.
- Wash off splashes immediately with soap and water.
- Any eye contamination must be rapidly irrigated with copious amounts of clean water, and immediate medical attention sought.
- Please refer to Material Safety Data Sheet for additional information.
- CPR 614 – Bund Coat 3 shall be applied strictly in accordance with the manufacturer’s instructions.
