Environmental Testing

AAC provides testing services for accelerated weathering and outdoor exposure of coatings and components for solar and wind energy.

AAC is equipped with the following devices for weathering:

• Climate chamber for
  • thermal cycling down to -40°C and
  • Damp heat tests at 85°C / 85% humidity
• Q-Lab QUV SE accelerated weathering tester to simulate sunlight, rain and dew with a UVA-340 light source [1].
• Q-Lab Q-Sun Xe-3 HS xenon test chamber to simulate the damage caused by full spectrum sunlight and rain (optional) with a daylight F filter [2].
• Autoclave for conduction of pressure cooker test (PCT 121°C in saturated vapour for 83h), a fast method for material screening.

Tests are accompanied by surface and material characterisation:

• Surface energy, contact angle, roll-off angle
• Adhesion to substrate (cross-cut)
• Color change
• Mechanical testing: tensile strength, e modulus, shear force.
• Optical and electron microscopy including embedded cross-cuts

At AAC we often build test setups from scratch to meet customer need. If your test problem is not included above, just contact us!
