As a global-playing technological leader in the sector, we have a valuable resource that can generate added value for you and tackle highly specific issues - our fully equipped, state-of-the-art laboratory, and the expert team that comes with it.
As well as precise, ´spot-on´ matching across the entire spectrum of powder-coating technology (e.g. unique special effects such as metallics, haptic surfaces and powder coatings with specific properties etc.), we can also offer you our extensive arsenal of testing devices (for e.g. weathering tests, corrosion protection tests, mechanical testing, grainsize distribution, chemical stability, many different types of special test, etc.).
Alongside our wide range of different services, we also offer you the unique opportunity of having flexible client-specific analyses carried out on your behalf, to give you the information that you need as the basis for your decision-making.

Prototyping of metallic and special effects
Effect nuancing with reference to specimen and gloss sample, 1 x 0.8 kg specimen powder and 1 QV panel.
Sample QV-sized panels as per current TIGER standard warehouse range; DIN A4 formats for all colors and effects from the TIGER Architectural Service (TAS).
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.
Salt spray testing based on ISO 9227
This test permits checking of the entire system (substrate, pre-treatment, powder and curing condition). Testing is possible on both aluminium and steel. Testing duration: 1000 hours.
Determination of resistance to humidity (testing under tropical conditions) based on DIN EN ISO 6270-2
Coating adhesion test in constant-condensation atmosphere to verify the pre-treatment quality.
Testing duration: 1000 hours.
Kesternich test, with alternating condensation in sulphur-dioxide-containing atmosphere, based on EN ISO 3231 / DIN 50018
Coating adhesion test in alternating-condensation atmosphere (industrial climate) to verify the pre-treatment quality. Testing duration: 30 cycles.
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.
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.
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.
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.

Particle size distribution

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.
