Processing
Pre-treatment
If the surface finish of the MDF ex-works does not meet the quality requiremens of the end product, the surface has to be sanded. This will ensure that the material has an evenly smooth surface and is free of any contaminants, minor scratches, dust, grease, etc. For more information, see IGP-TI 111.
Coating devices
All conventional electrostatic systems with corona charging.
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
100 μm - 140 μm
A homogeneous coating result with textured coatings or article-and color specific differences in hiding power may require higher coating thicknesses. The corresponding processing guidelines must be observed.
For a pre-calculation of the required powder coating quantity, the necessary coating thickness must be determined for each article.

Curing conditions
| TObject | t min | t max |
|---|---|---|
| 125 °C | 5 minutes | 9 minutes |
| 130 °C | 3 minutes | 7 minutes |
| 140 °C | 2 minutes | 5 minutes |
Due to the limited thermal conductivity, the use of infrared- (electric / gas catalytic) or convectional - infrared combined ovens is recommended.
In order to determine ideal curing conditions, we recommend practical trials with the respective object and curing oven.
The curing conditions must be carefully controlled. Powder coatings cured outside the curing window may show deficiencies in the film flexibility. Our technical customer service will advise you.

Reclaimability
Small portions of recycled powder can be added, automatically if possible, to the fresh powder. Important: Keep overspray to an absolute minimum.

Overcoating
For matte to semi glossy finishes the following sanding steps are recommended:
P220 or P240 / (P280 optional) / P320
For high gloss finishes the following additional sanding steps are recommended:
P400 and optional P500
A full cure of the primer leads to an optimal sandability.

Paint removal and disposal
After use, coated goods should be supplied to the normal recycling process. The disposal methods for sludges or residual powders must be observed in accordance with the local official provisions whilst taking Waste Code “080201 Coating Powder Wastes” in accordance with the European Waste Catalogue into consideration.
