Recommended Film Thicknesses & Theoretical Coverage
| Recommended film thicknesses | Theoretical coverage | |
|---|---|---|
| Wet | Dry | |
| 75µm | 40µm | 13.0 m²/l |
| 155µm | 80µm | 6.5 m²/l |
Practical coverage depends on the application method, painting conditions and the shape and roughness of the surface to be coated.
Drying Times
| DFT 40µm | 5℃ | 10℃ | 23℃ | 35℃ |
|---|---|---|---|---|
| Dust dry, after | 50 minutes | 20 minutes | 10 minutes | 5 minutes |
| Touch dry, after | 2 hours | 1 hours | 30 minutes | 15 minutes |
| Recoatable, after | 5 hours | 3 hours | 1 hours | 30 minutes |
Drying and recoating times are related to the film thickness, temperature, the relative humidity of the air and ventilation.
Surface Preparation
- Oil, grease, salts and dirt are removed by appropriate means. (ISO 12944-4)
Steel surfaces:
- Blast clean to grade Sa2½. (ISO 8501-1)
- In order to get the best performance the surface profile should be medium grit. (ISO 8503-2)
Recommended Topcoats
- Temacoat GPL-S Primer
- Temacoat GF Primer

Application Conditions
- All surfaces must be clean, dry and free from contamination.
- The temperature of the ambient air, surface and paint should not fall below 5ºC during application and drying.
- Relative humidity of the air should not exceed 80% during application and drying.
- The surface temperature of steel should remain at least 3°C above the dew point.
- Good ventilation and sufficient air movement is required in confined areas during application and drying.
Note! There is a natural tendency of this coating to chalk, discolour or yellow unevenly. It is recommended to use polyurethane topcoat when there are high aesthetical requirements on colour appearance.
Mixing Components
- First stir base and hardener separately.
- The correct proportions of base and hardener must be mixed thoroughly before use.
- Use power mixer for mixing.
- Insufficient mixing or incorrect mixing ratio will result in uneven drying of the surface and weaken the properties of the coating.
Application
For airless spraying:
- The product is thinned depending on the temperature of the components and shape of the object approximately 0–5%.
- Recommended nozzle tip is 0.015"–0.021" and pressure 120–180 bar.
- Spray angle shall be chosen according to the shape of the object.
For brush application:
- Product should be thinned according to the circumstances.
- Sharp edges, corners, weld seams and other areas difficult to cover properly by spray application should be coated by brush before the spray application.
