  heroal hwr powder coating

  For decades, heroal has set international quality standards in the field of aluminium coating. With the best values in terms of colour stability, gloss retention, weather resistance and UV-protection, heroal hwr powder coatings meet the highest demands of Qualicoat’s class 2 and GSB’s master quality (quality seal for piecework coating) – of course, fully complying with all ecological requirements.

  Coating process:

  1. aluminium base material
  2. chromium-free passivation
  3. heroal hwr powder coating

• heroal Surface Design (SD)

  heroal Surface Design (SD)

  With heroal Surface Design, aluminium windows, doors, curtain walls or patio roofs can be created with wood, concrete or rust looks. After having been heroal hwr powder-coated, the profiles are wrapped in a transfer foil with sublimation ink. Extreme heat creates a vacuum, and the ink cures into the powder coating. Then the foil is removed, revealing the high-quality surface look. The bonding of heroal SD and the hwr powder coating underneath is very strong. That way, heroal Surface Design (SD) provides for surfaces of excellent quality.

  Coating process:

  1. aluminium base material
  2. chromium-free passivation
  3. heroal hwr powder coating
  4. transfer film with sublimation ink

• heroal 2-layer thick coating

  heroal 2-layer thick coating

  Thanks to coatings using heroal 2-layer thick coat, roll-formed aluminium parts, like slats for roller shutters and roller doors, are especially colour-intensive and colour-fast, as well as abrasion-proof and weather resistant. The thick coat is applied in a rolling process and then stoved at 240 °C. After the application of a clear coat, the elements are finally roll-formed. This is first class quality. Therefore, the classification society Germanischer Lloyd certified the 2-layer thick coating as suitable for being used on ships.

  Coating process:

  1. aluminium – base material
  2. pre-treatment
  3. prime coat
  4. clear coat

• Eloxal process

  Eloxal process

  During the Eloxal process, the electrolytic oxidation of aluminium, direct current turns electrolytes containing oxygen on the aluminium surface into oxygen. The following reaction of the oxygen and the surface creates a build-up of aluminium oxide. The oxide provides for corrosion protection and also prevents the aluminium from further oxidation, while at the same time preserving the metallic appearance of the surface.

  Coating process:

  1. aluminium base material
  2. barrier coat
  3. porous Eloxal
  4. metal oxides
  5. sealing

• Certifications and partnerships
  Certifications and partnerships

  heroal coating technologies and design stand for highest quality. They provide for colour stability, protection against UV radiation, gloss retention and especially weather-resistant surfaces. This is confirmed by the exclusive partnership with Les Couleurs® Le Corbusier, and also by various awards from Qualicoat to GSB (quality seal for piecework coating).
