Pre-treatment
Suitable for overcoating already painted surfaces, especially for the protection of metallic coatings.
The suitability of the pretreatment method used is generally to be tested by the coater in advance with appropriate test methods. We refer to the guidelines of the GSB International, Qualicoat and Qualisteelcoat certifications. For further information: see also our special leaflet on pre-treatment (IGP-TI100).
Coating devices
All commercially available electrostatic systems, both corona and tribo charge systems.
For the construction and operation of powder coating plants, the following regulations must be complied with: ATEX RL 2014/34/EU, EN 50177, DIN EN 16985.
Recommended film thickness
60 μm - 80 μm
A homogeneous coating result with textured paints or colour or article-specific differences in hiding power may require higher Film thicknesses. The corresponding processing guidelines must be observed.
For a preliminary calculation of the required powder coating quantity, the required Film thickness must be determined for each specific article.
Curing conditions
| TObject | t min | t max |
|---|
| 180 °C | 15 minutes | 25 minutes |
| 190 °C | 10 minutes | 15 minutes |
| 200 °C | 5 minutes | 10 minutes |
In order to determine ideal curing conditions, we recommend practical trials with the respective object and curing oven.
Application
Coloured transparent coating powders are mainly suitable for small parts or pipe constructions and not for large, flat surfaces. Furthermore, the visual impression is very much influenced by film thickness and homogenity: Different film thicknesses result in different colour shades! For this reason, it is not advisable to recoat coloured-transparent powder coatings for repair purposes.
Devices and coating systems must be thoroughly cleaned before using the powder.
Reclaimability
Small portions of recycled powder can be added, automatically if possible, to the fresh powder. Important: Keep overspray to an absolute minimum.
