Processing

Pre-treatment

The substrate must be free from oil, grease and oxidation products. The pretreatment depends on the type of substrate and the corrosion protection to be achieved. We recommend the following pretreatments:

Aluminium
  • Chromating according to DIN EN 12487
  • Pre-anodization
  • Chrome-free pretreatment according to GSB International and QUALICOAT specifications
Steel
  • Zinc phosphating
Galvanised steel
  • Zinc phosphating
  • Chrome (III) passivation
  • Chromating according to DIN EN 12487

For improved corrosion protection for applications on steel / galvanised steel, the use of corrosion protection primer IGP-KORROPRIMER 10 or IGP-KORROPRIMER 60 is recommended.

The suitability of the pretreatment method used is generally to be tested by the coater in advance with appropriate test methods. The minimum requirement for aluminium substrates / galvanised steel components is to carry out a boiling water test with a subsequent cross-cut adhesion and tape test. 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-TI 100).

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 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
TObjectt mint max
180 °C20 minutes25 minutes
190 °C15 minutes20 minutes
200 °C10 minutes15 minutes
In order to determine ideal curing conditions, we recommend practical trials with the respective object and curing oven.
Reclaimability
Small portions of recycled powder can be added, automatically if possible, to the fresh powder. Important: Keep overspray to an absolute minimum.

Overcoating
Preliminary tests are mandatory for overcoating painted surfaces.
Printing and glueing
Preliminary tests are mandatory for printing and glueing of painted surfaces.
Protection of coated parts
Coated parts should be packed after cooling with suitable materials without plasticizers. They should be stored protected from the weather to avoid the formation of condensation and thus water spots on the coating.
Cleaning
The coated parts must be cleaned according to the directives RAL-GZ 632 or SZFF 61.01.
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.
