- Product Description
IGP-HWFclassic 5903B is a premium smooth-finish and transparent powder coating material from the IGP-HWFclassic 59 product range for highly weather-resistant two-coat applications in the architecture and industry sector.
- Properties
High resistance against climatic influences such as UV radiation and moisture as well as industrial emissions and other atmospheric components. Surface with excellent gradient and good mechanical properties. Low level of yellowing with directly heated gas ovens.
Applications & Uses
- Markets
- Compatible Substrates & Surfaces
- Application
Can be used as a “topcoat” for the finishing of metallic coats in order to protect against corrosion, fingerprints, abrasion or to achieve greater visual depth for
- Facade components
- Motor housings
- Infrastructural facilities
- Industrial component groups
- Cleaning
Coated parts to be cleaned in compliance with the regulations RAL-GZ 632 or SZFF 61.01. For pearl-mica effect, the Technical Information IGP-TI 106 must also be observed.
- Stripping and Subsequent Use Phase
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 Catalog into consideration.

Pre-treatment
The substrate to be coated must be fr ee of oxidation products, or residue from scale, oil, grease or release agents. Depending on application range and the planned usage duration, a pre-treatment suitable for the substrate is used:
- Aluminum substrate:
- Chrome-free pre-treatment: Preferred approved systems from GSB and Qualicoat
- Chromatising: DIN EN 12487
- Pre-anodisation: Also available
Steel substrate
- Zinc or iron (Fe) phosphating
- Galvanized sheet metal: Chromatising in accordance with DIN EN 12487
For improved corrosion protection for applications on steel / galvanized steel, the use of corr osion protection primer IGP-KORROPRIMER 10 is recommended. The suitability of the pre-treatment 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 intended for architectural applications is performing a boil test / pressure cooker test with a subsequent crosscut adhesion and pull-off test. We refer to the guidelines of the GSB certifications and Qualicoat. For further information: see also our special leaflet on pre-treatment (IGP-TI 100).
Coating equipment
All commercially available electrostatic systems, both corona and Tribo charge systems. Exceptions are Pearl Mica and Crystal Color effects which must be processed only 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.
Recyclability
Small proportions of recycled powder should be added, automatically if possible, to the fresh powder. For Pearl Mica effects, refer also to processing instruction VR 201.
