POWDER COATING - surface & design
Powder coating
Powder coatings, also called stove enamel finishes, adhere excellently to the substrate. They may be milled and offer both a high chemical and thermal resistance.
Electrostatic polyester resins are sprayed on electrically grounded parts by means of compressed air. Electrostatic attraction makes a pre-defined amount of powder adhere to the component. In the smelting furnace the polyester resin is reduced into a fluid state and forms a continuous polyester resin film which is characterized by its high resistance against weathering and mechanical stress.
Electrostatic powder coatings represent an environmentally sound technique as they do completely forego the use of solvents and are characterized by a highly efficient recovery of residual powder (about 98 %).
Potential component size:
length 7000 mm x width 800 mm x height 2000 mm
Powder coating RAL Standard colors
RAL standard colours are available at short notice from our warehouse. With 75% ±10% the gloss level is that of silk gloss. Compared to high-gloss surface finishes they show a considerably higher resistance against mars and weathering phenomena.
Please ask for specimen or samples!
Here you can find our online colour chart with RAL - colours available from stock.
Special - powder coatings
Besides RAL standard colours there is a whole range of special-effect powder coatings. The developments in this field open up an even greater offer of colours and possibilities. Depending on the powder composition a huge variety of effects can be achieved. Almost unlimited aesthetic possibilities are thus offered from matt to high gloss, from fine to coarse textures and from metallic to glitter coatings. Please contact us for further information on indoor or outdoor applications, prices, orders, delivery times etc.

High quality powder coating
Our standard quality is perfectly suited for aplications with normal environmental and weather conditions with standard UV-radiation. For special requirements with high UV- and weathering resistance we recommend the use of high weather resistant powder qualities HWFclassic or HWFsuperior. All HWF powders include the DURA®clean technology with dirt-repellent finishing features.

UniversAL Powder coating cleaner
UniversAL Cleaner provides cleaning & protection for powder coated surfaces. It can be applied on elements with smooth coloured varnish or structured and metallic finishes. The UniversAL cleaner is a special product for the maintenance and the protection and of powder coated architecture elements. The ingredients combine care components, solvents and preserving agents. UniversAL also protects surfaces from weather effects and environmental pollutants. There are no polishing agents or silicon compounds or aromatic hydrocarbons. UniversAL Cleaning & Protection for powder-coated or further coated / anodised aluminium surfaces comes in a set with a 100 ml bottle plus cleaning cloth or in a 500 ml bottle.
Pretreatment
The prerequisite for a durable protection and beautiful appearance of coated metal surfaces is their appropriate pretreatment. Adhesion-reducing impurities (e.g. rolling oils) are detached by degreasing and etching and the natural oxide layer is removed.
In a second procedural step a new layer will be applied, generally a yellow chromate or anodising layer. This very thin chromate or anodising layer conveys excellent adhesion properties to the coating and passivates the metal surface (see ill.). The passivation along the metal edges and of spots with deep defects in the coating film that reach down to the metal surface prevents furthermore corrosion-creep in the coating.
Between the operations the material is thoroughly rinsed. The last pretreatment step consists in the drying of the coating in the convection oven.
Powder coating the process
Subsequent to a 100% drying of the chromate layer the polyester resin is electrostatically charged in a closed booth and is sprayed on electrically grounded parts by means of compressed air. Residual powder is recovered and recirculated.
Aluminium surface with coating
At a baking-in temperature of about 180°C the powder begins to smelt in a first step while fixing within the chromate film and a crosslinking reaction occurs. As a result, a continuous and firmly adhesive polyester resin film emerges, which is characterized by a high weathering resistance and shows good mechanical properties (see ill.). The film thickness is of 80 µm ± 20 µm.
Properties
For outdoor powder coating applications we use high-end polyester resins that perfectly meet the demands of weathering exposure (see quality, GSB). Appearance and applications of the powder coating may be adjusted by the use of the respective formulation.
Powder coated aluminium products may be milled and the powder coating offers a high chemical and thermal resistance.
Powder coated metal components combine high functionality, an aesthetic appearance, protection and low maintenance. A broad offer of shades and textures provides you countless possibilities to design surfaces and thus design the appearance of the idea you put in aluminium or steel.

DURA®clean
DURA®clean – the technical effect
Coatings equipped with DURA®clean possess a hydrophobic surface thanks to a highly effective admixture. Dirt particles cannot easily adhere to the coating's surface and are beaded away by water. The additives used are distributed throughout the coating's structure and have a permanent effect, in contrast to a subsequent (temporary) application of preservatives. This improved dirt-repellence requires fewer cleaning interventions and implies lower maintenance costs in general. Moreover, the costs for each individual cleaning intervention are reduced all the same.
The robust effect
Coatings furnished with DURA®clean withstand cleaning better and excellent results are obtained from use of non-abrasive cleaning with sponges and water.
DURA ®clean is available as an optional extra in all standard qualities of the whole range of colors.
Additives are integrated during powder production. All HWF powders are equipped with the DURA ®clean technique.
