~1.3 kg/l

~100 % by volume
~100 % by weight

Upon request

Dry heat up to approx. + 100°C

≤ 1 x 10⁸ Ω

Min. + 8°C

Max. 80 %, surface temperature shall be at least 3 K above dew point.

Min. + 8°C

Overcoating with itself within 2 days (+ 20°C), e.g. overlappings when application work is section by section.

In case of longer waiting times the surface must be activated by sweep-blasting.

Drying Time at + 20°C:

For curing procedure there is no need of air ventilation.

Due to electrical conductivity of the coating, this may only be assessed visually.

Theoretical material-consumption / coverage without loss for medium dry film thickness:

Steel:
Remove all weld spatter, then grind welds and joints in accordance with EN 14879-1.

Blast-cleaning to Sa 2 ½ according to ISO 12944-4.

Free from dirt, oil and grease.

Average roughness depth R_Z ≥ 50 microns.

Stir component A very thoroughly using an electric mixer (start slowly, then increase up to approx. 300 rpm). Add component B carefully and mix both components very thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into clean container and mix again shortly as described above. During mixing and handling of the materials always wear protective goggles, suitable gloves and other protective clothings.

By brush and roller:

• Suitable only for the repair of small areas or to pre-coat edges

Airless-spraying:

• High pressure airless equipment (capacity ≥ 18 l/min)
• Pump directly (without connected suction hose)
• Pressure min. 200 bar
• Hose: max. 20 m length, ⅜ inch resp. 10 mm internal diameter, directly before gun approx. 2 m hose, ¼ inch
• Nozzle size ≥ 0.48 mm
• Spraying angle: 40° - 80°

Temperature of equipment and material min. + 20°C.

At lower temperatures insulation of the hose and the use of an inline heater is recommended; particularly when long hoses are used.

Repair works:

Clean and prepare damaged areas by sanding or sweep blasting of areas to be coated and ensure thorough removal of dust. Then overcoat as soon as possible.
