CPR 602 – Acid Resistant Epoxy Paint

Description

Acid Resistant  Epoxy Paint

CPR 602 – Acid Resistant Epoxy Paint 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.

Typical Properties

• 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

Application Procedure

Surface Preparation Concrete

• 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.

Surface Preparation Steel

• 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.

Priming

• 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 602 Acid Resistant Epoxy Paint may be applied directly.

Mixing

• 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.

Application

• 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.

Equipment Cleaning

• Clean equipment with CPR 200 – Tool Clean Solvent prior to curing of the coating.

Curing

• 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 602 Acid Resistant Epoxy Paint has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions.

Packaging

• CPR 602 – Acid Resistant Epoxy Paint is supplied in 5kg and 15kg packs

Coverage

• 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

• 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 Department for specific advice.

Limitations

• 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 602 – Acid Resistant Epoxy Paint shall be applied strictly in accordance with the manufacturer’s instructions.
• For specific advice regarding any aspect of this product, please consult our Technical Department.
