Description

FEATURES

  • High thermal stability: resists temperatures up to 600°C.
  • Excellent coverage.
  • High durability.
  • Quick drying at room temperature.
  • Very good resistance to temperature fluctuations.
  • Good weather stability. Although some loss of gloss can be noticed after extended exposure.
  • Totally lead and chromate free.
  • No chlorinated and no aromatic solvents.
  • Aerosols use dimethylether (DME) propellant for controlled application and film properties.

APPLICATIONS

  • Stove pipes
  • Stoves
  • Heaters
  • Kilns
  • Incinerators
  • Chimneys
  • Exhaust manifolds
  • Headers
  • Engines
  • Ovens
  • Steam pipes

DIRECTIONS

  • Shake aerosol can very well for at least one minute after agitator ball is free. Stir or mix bulk product well to obtain a homogeneous dispersion. Repeat frequently while using.
  • Apply to a clean, degreased, dry surface for best results. Remove rust and scale with a wire brush.
  • Apply in light, even coats; best results are obtained with 2 lighter rather than 1 heavy coat. Additional coats can be applied after 15-30 minutes.
  • Complete curing occurs during use, typically after 1 h @ 200°C or 45 min. @ 250°C.
  • When spraying is finished, clean aerosol valve by turning can upside down and pressing button until only propellant escapes. If clogging occurs, remove button and clean orifice with fine wire.
  • Do not use on energised equipment. Use in well ventilated area.
  • A safety data sheet (MSDS) according EU directive 93/112 is available for all CRC products.
