Applicazione
Pretrattamento
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:
Acciaio
- Blasting (at least SA 2 ½)
- Iron phospating
- Zinc phosphating
Acciaio zincato
- 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).
Impianti di verniciatura
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.

Spessore del film consigliato
80 μm - 100 μm
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.

Condizioni di cottura
| Toggetto | t min | t max |
|---|---|---|
| 160 °C | 10 minutes | 30 minutes |
| 170 °C | 6 minutes | 20 minutes |
| 180 °C | 5 minutes | 13 minutes |
| 190 °C | 3 minutes | 10 minutes |
Per accertare le condizioni di cottura migliori si consiglia, in ogni caso, di effettuare prove pratiche con il rispettivo oggetto e forno di polimerizzazione.
Recupero
Small portions of recycled powder can be added, automatically if possible, to the fresh powder. Important: Keep overspray to an absolute minimum.

Sovraverniciabilità
Preliminary tests are mandatory for overcoating painted surfaces.
Stampaggio e incollaggio
Preliminary tests are mandatory for printing and glueing of painted surfaces.
Protezione delle superfici verniciate
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.
Pulizia
The coated parts must be cleaned according to the directives RAL-GZ 632 or SZFF 61.01.
Rimozione e smaltimento della pittura
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.
