Powder coating in 8 steps

Pickling and degreasing
Removal of contaminants such as oil, grease, dust, rust, oxides or laser skin. This prepares the parts for the conversion reaction..
1
HLT - sproeikamer 5
Rinse
Stops the reaction of the pickling and degreasing process by removing all chemical products from the surface.
2
Rinse with demineralized water
Make the surface salt-free and avoid conversion bath contamination.
3
Passivation with nanotechnology
Apply an environmentally friendly anti-corrosion layer through a reaction with small molecules - for a better protection against damage and better adhesion of the powder coating.

✓ extremely good adhesion of the coating to the metal surface​
✓no undermining of the coating in the event of damage
✓ corrosion protection
✓ self-healing property
4
Remove salt residues
Remove smallest salt residues to stop the possible reaction and to prevent conversion.
5
Drying
Evaporate all remaining moisture and prepare the parts for powder coating.
6
HLT - elektrostatisch poederlakken2
Electrostatic powder coatings
A part connects to ground so it attracts all electrostatically charged powder particles leaving the paint gun - also those lost by overspray during conventional paint spraying.
7
HLT - moffelen in moffeloven
Muffling in a muffle furnace
In a 140° to 220°C furnace, the solid powder coating particles melt into a liquid, viscous (paint) form. It hardens into a fixed coating.

Corrosion classes

Corrosion classes C1 t.e.m. C5-M are possible using to a combination of different raw materials and a 1 or 2-layer paint system.

Less transport =
less damage risk

Because HLT can powder coat all parts itself, no additional transport is required. This saves in transport costs. At the same time minimizes the risk of transport damage. This way you get the parts faster and in perfect condition.

Looking for the right RAL colour?

Take into account the difference between the colours on your screen and the actual RAL colours. This is due to the settings and quality of your monitor. Using a RAL-colour chart, you’ll find the right colour.
