testing

accelerated weathering

Exposure to natural weathering in Florida, based on ISO 2810
Testing of the panels takes place in Miami, in a south-facing location. The warm and humid climate of South Florida is ideal for real-time weathering tests. The duration of weathering will depend upon the system to be tested: 1 year for standard polyester, 3 years / 5 years for superdurable, and 10 years for fluoropolymer.

Accelerated weathering based on EN ISO 11341
An accelerated weathering test simulates, over a short period of time, the influence of moisture, temperature, and of the destructive components of sunlight that a coating has to endure in outdoor use.

It serves to differentiate the quality level with reference to the ‘standard’, ‘superdurable’ and ‘ultra-durable’ weathering specifications. Due to the testing duration, this test provides figures with very good comparability to those obtained from exposure to natural weathering in Florida. Testing duration: 300 hours.

UV-B 313nm based on DIN 53384
A UV-B test simulates, over a short period of time, the influence of UV radiation on the surface finish. This is an even faster test method for determining the weathering stability.

mechanical testing

Cross-cut test (based on DIN EN ISO 2409)
Cross-cutting is a method for testing the adhesion of a coating to the preceding coat and to the substrate. A cutter blade and a template are used to make 6 vertical cuts and 6 horizontal cuts in the coating, down to the substrate. This test is used for determining the adhesion of the cured powder coating to the substrate. In the case of multi-coat systems, evaluation of inter-coat adhesion is also possible. Free of charge when test specimen is provided.

 

Free of charge if specimen is provided

 

Cylindrical mandrel bend test (based on DIN EN ISO 1519)
In the cylindrical mandrel bend test, sample panels are bent around cylinders of different diameters. This enables the deformability of the coating to be assessed. Free of charge when test specimen is provided.

 

Free of charge if specimen is provided

 

Drop impact test (based on EN ISO 6272 / ASTM D 2794)
This test allows the flexibility and adhesion of the coating to be assessed in the case of rapid deformation. The degree of adhesion is closely related to the pre-treatment quality. Free of charge when test specimen is provided.

 

Free of charge if specimen is provided

 

Erichsen cupping (based on DIN EN ISO 1520)
This test allows the flexibility and adhesion of the coating to be assessed in the case of slow deformation. The degree of adhesion is closely related to the pre-treatment quality. Free of charge when test specimen is provided.

 

Free of charge if specimen is provided

analytics

Being equipped with an extensive panoply of analytical measuring technology, we have the capability to perform both qualitative (identification) and quantitative analyses of a large number of chemical substances.

We can detect individual substances in complex chemical formulations/mixtures, even in the case of low substance dosages or trace impurities, using physical-chemical measuring principles such as FTIR spectroscopy, AAS and GS-MS, although we also have wet-chemical processes such as various versions of chromatography at our disposal.

It is always advisable to call on the analytics service when a damage investigation is needed in order to establish responsibility for damage that has already occurred, and/or where a higher reject rate is occurring in production. In this way, sources of error can be identified and permanently solved, and latent hazard sources can be discovered and eliminated.
