Surface resistance

Paints & Coatings

For decades, OFI experts have been involved in the testing and evaluation of coating materials and systems in order to safeguard the functions of surfaces. All relevant parameters of paints and coatings are tested, including the evaluation of the respective substrate.

With our know-how, we are available to the industry as a partner for many surface-relevant issues – from material selection and normative requirement reviews to damage analysis.

Our comprehensive testing offer

  • artificial weathering and/or aging as well as outdoor weathering, e.g.
    • by means of QUV or xenon lamps, e.g. “Kalahari” and “Florida Test
    • Sun simulation test DIN 75220
    • Climate change tests on coated components in the range -70°C to +150°C on component dimensions up to (4000x2400x2000)mm
  • Corrosive influences such as humidity, salt, harmful gases, climate change tests, e.g.
    • neutral salt spray (EN ISO 9227, NSS)
    • Condensation (EN ISO 6270-1, EN ISO 6270-2) and cyclic loads
    • SO2 exposure (Kesternich test; EN ISO 6988)
  • chemical influences

Our competence and experience

Our employees are there for your concerns…

  • In the event of damage: testing and assessment of coating materials and coatings; based on this, preparation of remediation concepts, external monitoring and control of remediation work
  • For the body assessment incl. Evaluation of the base material and its pretreatment or preparation
  • In the determination of the resistance and aging behavior
  • During the material and optical characterization
  • In trace analysis (e.g. in the case of alleged parking damage).
  • For advice and support in material selection and process optimization
  • With regard to normative requirement verification, certification and conformity assessment, e.g. tests according to the specifications of the TL of ÖBB or DB.
  • For approval tests (e.g. to obtain the Austrian Ecolabel for interior wall paints, OFI Cert or GSB approval for powder coatings)
  • During auditing
  • For company-specific training
