app.print.technical_data_sheet.processing.title

app.print.technical_data_sheet.processing.substrates

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:

Steel
  • Blasting (at least SA 2 ½)
  • Iron phospating
  • 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 18 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).

app.print.technical_data_sheet.processing.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.
app.print.technical_data_sheet.processing.recommended_film_thickness
80 μm - 100 μm
To achieve a uniform finish with textured coatings, or where there are colour- or product-specific differences in hiding power, higher film thicknesses may be required. The relevant processing guidelines must be followed.
To estimate the quantity of powder coating required in advance, the necessary Film thickness must be determined on a product-by-product basis.

160 °C 10 minutes 30 minutes
170 °C 6 minutes 20 minutes
180 °C 5 minutes 13 minutes
190 °C 3 minutes 10 minutes
The oven temperature should be limited to 200°C

In order to determine ideal curing conditions, we recommend practical trials with the respective object and curing oven.
app.print.technical_data_sheet.processing.reclaimability
Small portions of recycled powder can be added, automatically if possible, to the fresh powder. Important: Keep overspray to an absolute minimum.

Preliminary tests are mandatory for printing and glueing of painted surfaces.
app.print.technical_data_sheet.more_information.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.
app.print.technical_data_sheet.more_information.cleaning
The coated parts must be cleaned according to the directives RAL-GZ 632 or SZFF 61.01.
app.print.technical_data_sheet.more_information.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.
