Our test laboratory performs a wide range of accredited tests for evaluating the resistance of materials, surfaces, and components to liquid or semi-solid media. These investigations assess the behaviour of materials when exposed to substances that may occur during use, cleaning processes, or direct skin contact.
The tests cover resistance to sweat, skin oils, oleic acid, sunscreen products, insect repellents, cleaning and care agents, fuels, and lubricants.
They are applied to leather, artificial leather, textiles, plastics, foams, as well as interior components and surface materials used in automotive applications. The underlying test methods are based on international standards as well as OEM specifications from automotive manufacturers such as BMW, Mercedes-Benz, Volkswagen, Tesla, General Motors, and MAN.
Depending on the specific test method, defined test media are applied to the material surface under controlled conditions or the specimens are directly exposed to the respective media. This is followed by conditioning under specified climatic or temperature conditions and evaluation of colour change, swelling, tackiness, gloss variation, surface damage, loss of adhesion, soiling, or changes in mechanical properties.
