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:

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

For improved corrosion protection for applications on steel / galvanized 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 aluminum substrates / galvanized 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
2.36 mil - 3.15 mil
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
356 °F10 minutes30 minutes

392 °F5 minutes10 minutes
In order to determine ideal curing conditions, we recommend practical trials with the object in question and curing oven.
Application
Primer coating with IGP-HWFthermofer 531M, layer thickness approx. 60–80μm. After the coated substrate has been cured and cooled, “transfer printing” takes place, i.e., the transfer of a motif specified on paper or film, such as wood grains, under the application of heat, on or in the substrate. The corresponding printing papers are included in the scope of delivery by the machine supplier. Decoration types: 1. MIROGLIO - DECOTRANS®ALU 2. SUBLIK - HEAT TRANSFER FILM SUBLIK 3. DEOCRAL SYSTEM - HEAT TRANSFER FILM DECORAL SYSTEM in accordance with Qualideco license PS-008
Reclaimability
Small portions of recycled powder can be added, automatically if possible, to the fresh powder. Important: Keep overspray to an absolute minimum. Processing instruction VR 214 must be observed.

Overcoating suitability
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.
