Applications & Uses

Markets: Building & Construction,
Paints & Coatings
Applications: Paints & Coatings — Industrial Coatings
Agricultural & Construction Equipment
Building & Construction — Infrastructure, Roads & Paving
Pavement, Highways, Roads & Bridges
Application Method: Brush,
Roller,
Spray
Applications: With spray gun, by airless spray coating, by paint brush, or by roller. During application of this paint by roller - the foaming is possible, so it is suitable to add antifoam agent to this paint. The coating temperature should not be lower than +15 °C, the humidity of air should not exceed 70 %.
Standard paint application steel structure: primary surface treatment – cleaning, degreasing, or blasting to the surface cleanness Sa 2.5 (ISO 8501-1)

1-2x crosswise priming coat with Rokoprim EP S 2300 (optimum coat thickness: 40-80 μm in 1 layer, recoating interval has to be 24 hod.)

2x top coat with Rokopur email RK 400 (2x50 μm, recoating interval has to be min. 4-6 h)

Note:
Spraying application of metallic colors (for example RAL 9006, 9007) must follow the same application conditions (thickness, dilution, pressure, type of nozzle, etc.). Any deviation from the standard application method causes a change and appearance of color shade. Application by roller painting, or by brushing is not suitable for these color shades.

Technical Details & Test Data

Technical Details: Hardening
Rokopur Tužidlo hardener RK 500 (6:1 by weight, 4,8:1 volume)

Pot life
4-6 h at 20 °C

Thinning
The recommended viscosity (approx. 18 – 30 s (F4/20°C acc.to ČSN 673013) is to be achieved by adding 10-15 % of the
Rokopur Ředidlo thinner RK 010.

Cleaning Rokoředidlo C 6000
Drying
Air drying:

Degree 1: in 90 min at 20 oC

Degree 4: in 16 h

Oven drying:

If accelerated drying process (by circulating air) is used, following drying times (the air blasting time of 15 min is to be kept in any case!) can be achieved:

40 min at 80 °C or

30 min at 100 °C.
