As a global player and technological leader in the powder coating industry, TIGER’s laboratory is a valuable resource that can generate added value for you. TIGER’s fully equipped, state-of-the-art laboratory, and the expert team that comes with it, can help you tackle any number of technical issues.

Besides 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), TIGER can also offer you an extensive arsenal of testing devices, such as weathering tests, corrosion protection tests, mechanical testing, particle size distribution, chemical stability and many different types of specialized tests.

Alongside our wide range of different services, TIGER also offers the unique opportunity of having flexible, client-specific analyses carried out on your behalf, to give you the information that you need to make a sound decision.

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 polyesters, 3-5 years for superdurables, and 10 years for fluoropolymers.

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 for outdoor application.

It serves to differentiate the quality level with reference to the ‘standard’, ‘superdurable’ and ‘hyper-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.

corrosion protection

Salt spray testing based on ISO 9227
This test allows to check the entire system (substrate, pretreatment, powder and curing condition). Testing is possible on both aluminium and steel. Testing duration: 1,000 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 pretreatment quality.
Testing duration: 1,000 hours.

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.

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 pretreatment 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.

Being equipped with an array of analytical measuring technology, TIGER has the capability to perform both qualitative (identification) and quantitative analyses of a large number of chemical substances.

TIGER 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. TIGER also has wet-chemical processes such as various versions of chromatography at our disposal.

It is always recommended 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.
