Description

Concrete Primer – Epoxy WB

CPR 401 Concrete Primer – Epoxy WB is a two pack, water dispersible Epoxy based primer clear coating, especially formulated to meet the technological and ecological requirements of modern building and industrial practice.

CPR 401 is non-flammable and solvent free, is low odour, and may be applied to dry or damp surfaces. The primer has excellent adhesion to most building materials, is non-toxic once cured, and consequently is a highly versatile material lending itself to application in many different types of location and circumstances.

Typical Properties

  • Excellent adhesion to dry or damp surfaces
  • Low odour
  • Easily applied
  • Taint free
  • Particularly good chemical and abrasion resistance
  • Economical and versatile

Directions for Use

Surface Preparation 

  • Surfaces should be sound, clean and free from standing water, laitance, oil, grease, and other contaminants.
  • New concrete should be allowed to cure for a minimum of 21 days.
  • Floors should be mechanically abraded, scarified, grit blasted or acid etched where any subsequent coating is to be applied over the CPR 401 Concrete Primer.
  • Note: For steel work a coat of CPR 410 Metal Primer – Epoxy WB is recommended as a primer instead of CPR 401 Concrete Primer.

Mixing

  • CPR 401 Concrete Primer – Epoxy WB is supplied in pre-weighed containers ready for mixing. Pour the contents of the BASE container into the CURING AGENT container and thoroughly mix, preferably by mechanical means until a uniform consistency is achieved. A low speed drill with paddle attachment is recommended for mixing operations.
  • Note: Thinning of the material is not usually necessary.  However, it is permissible to thin CPR 401 Concrete Primer – Epoxy WB by the addition of up to 20% by volume of clear water. This will reduce the viscosity and facilitate application.

Application

  • Apply by brush, roller or airless spray at a nominal rate of 5 m² per Kg.
  • As a sealer or clear coating, a second coat should be applied after a minimum of 16 hours, and before a maximum of 48 hours.
  • As a primer, overcoating may be commenced as soon as the initial milky appearance has cleared, typically after 2- 4 hours.
  • Ensure good ventilation during application.

Equipment Cleaning

Curing

  • CPR 401 Concrete Primer – Epoxy WB will be touch dry following 6 hours cure @ 20C.
  • Hard dry after 16 hours cure @ 20C.
  • Full chemical resistance will be attained following 7 days cure @ 20C. Good ventilation is essential to allow satisfactory evaporation of water from the film.

Storage and Shelf Life

  • Store in dry conditions, out of direct sunlight, at temperatures between 10°C and 25°C.
  • CPR 401 Concrete Primer – Epoxy WB has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions.

Packaging

  • CPR 401 Concrete Primer – Epoxy WB is supplied in 5kg and 15kg packs.

Coverage

  • A 5kg pack is sufficient to prime 20/ 25 m² of surface. (15kg pack pro rata).

Technical Data

  • Pot life @ 20ºC: 90 Minutes
  • Colour: Clear
  • Adhesion to dry concrete: 4.4MPa (concrete failure)
  • Adhesion to damp concrete: 4.1MPa (concrete failure)
  • Chemical Resistance: Excellent resistance to water, dilute acids, dilute alkalis, petrol, diesel, white spirit, skydrol, etc. Specific advice will be provided by our Technical Department.

Limitations

  • Do not apply to uncured surfaces.
