APPLICATION OF POWDER COATING

Powder coating allows for a simplified and eco-friendly application, with even and long-lasting finishes on metal supports.

Powder coating is a painting process that consists first of all in applying powder paint (epoxy, polyester, epoxy-polyester mixture) using electrostatic spraying. The latter will then be polymerised in a 200°C oven to obtain a layer of paint.

Advantages:

  • Many different aspects and colours.
  • Extremely high resistance to corrosion, chemical aggressions and fire.
  • Powder coating paint with no volatile organic compounds (solvents).
  • Very high elastic resistance, as well as to impacts and wear.
  • Powder coating can be applied to all metal materials

Powder coating is standardised according to several standards:

NF EN ISO 2813 – November 2014: Paints and varnishes – Determination of gloss value at 20 °, 60 ° and 85 °

NF EN ISO 2360 – October 2017: Non-conductive coatings on non-magnetic electrically conductive basis materials – Measurement of coating thickness – Amplitude-sensitive eddy current method

NF EN ISO 2409 – April 2013: Paints and varnishes – Cross-cut test

NF EN ISO 3231 – April 1998: Paints and varnishes – Determination of resistance to humid atmospheres containing sulphur dioxide

NF EN ISO 2810 – December 2004: Paints and varnishes – Natural weathering of coatings – Exposure and assessment

NF EN ISO 9227 – June 2017: Corrosion tests in artificial atmospheres – Salt spray tests
