Solids content

Vol. 66 % (DIN EN ISO 3233-2)

Temperature resistance

Dry: up to 180 °C, for a short time up to 200 °C.
Wet: up to approx. 50 °C

Chemical resistance

In a system resistant against industrial atmosphere, exhaust fumes, diluted inorganic acids, diluted alkaline solutions and salt solutions, many solvents as well as water and condensation.

Suitable Substrates

  • steel

Substrate Preparation

The surface has to be dry and free of fat, oil, dirt and dust.

  • steel: grid blasting Sa 2½ (DIN EN ISO 8501-1), surfce profile medium (G) (ISO 8503-1)

Preparation of Material

Stir component A until homogeneous. Then mix component A and B at specified mixing ratio, stir thoroughly (aprox. 3 min.) with a slow rotating stirrer (max. 400 r/min). Repot the mixture in a clean pot and stir again thoroughly.

Mix only the quantity, that can be applicated within the pot life.

Mixing Ratio

94 parts by weight comp. A
6 parts by weight comp. B

Method of Application

  • Brush
  • Roller
  • Airless spray application (spray nozzle pressure 200 bar, nozzle size 0.5 mm respectively 0.02 inch)
For airless spray application 2 – 5 % DisboADD 419 can be added, depending on the dry film thickness and application conditions.
