METALogic offers a lot of possibilities to test the effects of climate and light on the behaviour of coatings (and metals). By variation in temperature and %RH, by simulating the effects of acid rain (Kesternich test, dosing of SO2) or by exposure to light (simulation of the effects of (sun)light by means of Xenon arc exposure, UV exposure) the performance of metals and coatings under these circumstances can be evaluated.

The climate conditions are typically applied in a standardized way. In general accelerated ageing is the main goal of climate testing, so that potential differences in quality or performance can be established within a reasonable timeframe.

 

Some examples of climate tests performed by METALogic:

  • ASTM G87, ISO 3231 (Kersternich test)
  • ISO 6270-2 (condensation test)
  • ASTM D3451, ASTM 6695, ASTM D7869, ISO 16474-2, ISO 11341, ISO 4892-1, ISO 4892-2 and others (exposure to specific lighting conditions)

(Cyclic) salt spray tests

Traditionally coatings are tested by subjecting them to an aggressive environment. This is for example the case in the neutral salt spray test (ISO 9227 NSS or ASTM B117). In this test coatings are exposed [...]

Delivery and evaluation of corrosion coupons

The evaluation of metal coupons (corrosion coupons or test plates) or objects after exposure typically includes determination of the (uniform/localized) corrosion rate, corrosion mechanism, analysis of [...]

Evaluation of plastics

We can perform following evaluation on polymers and elastomers in the context of exposure testing: Visual evaluations: Macroscopic and stereomicroscopic evaluation of the surface Assessment of changes in [...]

Evaluation of coatings

Evaluation of coatings is done primarily by means of visual evaluation. The condition of the coating is evaluated by assessing blistering, rust formation of the substrate, creepback at an artificially [...]
