The electrostatic discharge resistance is the measured contact resistance between an electrode on the coated surface and the ground potential. The measurement is conducted in line with DIN EN 61340-2-3 “Test methods for determining the resistance and resistivity of solid planar materials used to avoid electrostatic charge accumulation”.

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
  • Iron phospating
Galvanized steel
  • Zinc phosphating
  • Chrome (III) passivation
  • Chromating according to DIN EN 12487

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
With higher layers, the powder coating becomes insulating.
Curing conditions
TObjectt mint max
320 °F20 minutes40 minutes
338 °F15 minutes30 minutes
356 °F10 minutes20 minutes
In order to determine ideal curing conditions, we recommend practical trials with the object in question 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. Processing instruction VR 214 must be observed.

500 kg cardboard container with 25 antistatic PE-liners each 20kg
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.
