Processing
Pre-treatment
Suitable for overcoating already painted surfaces, especially for the protection of metallic coatings.
The suitability of the pretreatment method used is generally to be tested by the coater in advance with appropriate test methods. 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-TI100).
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
1.97 mil - 2.36 mil
Curing conditions
| TObject | t min | t max |
|---|---|---|
| 356 °F | 20 minutes | 25 minutes |
| 374 °F | 10 minutes | 15 minutes |
| 392 °F | 7 minutes | 12 minutes |
In order to determine ideal curing conditions, we recommend practical trials with the object in question and curing oven. Due to a few e-caprolactam emissions during the curing process it is necessary to take care for a good ventilation to comply with the permitted occupational exposure limits and concentrations.
Application
Devices and coating systems must be thoroughly cleaned before using the powder.
For IGP-DURA®than 8909B, the IGP processing guideline
VR 208 must also be observed.
For IGP-DURA®than 8909B, the IGP processing guideline
VR 208 must also be observed.
Reclaimability
Small portions of recycled powder can be added, automatically if possible, to the fresh powder. Important: Keep overspray to an absolute minimum.

Packaging
15 kg cardboard box with inserted antistatic PE liner
Overcoating suitability
For overcoating anti-graffiti powder coatings, sanding and preliminary tests are mandatory.
Printing and glueing
Preliminary tests are mandatory.
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.
Graffiti removal
The following procedure should be observed when removing grafitti: - The contact time of the gaffiti with the surface must be kept as brief as possible - Preliminary tests to select a suitable graffiti remover - Thorough rinsing of the cleaned areas with water - The contact time of the graffiti remover with the surface must be kept as brief as possible IGP recommendation: - Elite 007 grafitti remover from Crous Chemicals GmbH - Socostript T4210P from Socomore - Bonderite S-ST 1302 and Bonderite C-MC 400 from Henkel AG - or a different non-abrasive cleaner
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.
