Adhesive bonding technology gained popularity especially in the field of light weight design due to multi-material construction. It replaces traditional joining methods, e.g. welding, riveting, etc. and is found in automotive, aerospace, civil engineering and other applications.
At CEST we are focusing on the following:
- Characterization of bonding performance and failure pattern
- Impact of substrate pre-treatments
- Impact of environmental conditions
Special focus on automotive application includes:
- Lab scale automotive electrophoretic coating process
- Broad coverage of environmental aging tests
– Salt spray test
– Cyclic corrosion tests (e.g. VDA 621-415)
– Cataplasma test
Testing of adhesive bonds mainly performed are:
- Lap shear tests (according to DIN EN 1465)
- T-Peel tests
- Evaluation of failure pattern according to DVS 3302
- Others possible on request
Testing of coatings
We offer the following tests for the characterization of coatings, also in combination with corrosion tests and other tests:
- Cross cut test DIN EN ISO 2409
- Pull-off test for adhesion DIN EN ISO 4624
- Determination of scratch resistance DIN EN ISO 1518-1
- Cupping test DIN EN ISO 1520, DIN EN 13523-6
- Bend test (conical mandrel) DIN EN ISO 6860
- Resistance to cracking on bending (T-bend test) of coil coated metals DIN EN 13523-7
- Color measurement, measurement of gloss DIN EN ISO 2813
- Degree of blistering, rusting, cracking, flaking according to DIN EN ISO 4628-2, 4628-3, 4628-4, 4628-5 etc.
