Spectroscopy Discover some of our methods. NMR (Nuclear Magnetic esonance) High-resolution NMR spectroscopy is a method for the detailed structural elucidation of organic substances. The samples are placed in a strong magnetic field and irradiated with radio frequency pulses. The change in the magnetization of the elements (eg hydrogen and carbon) is observed depending on their chemical environment. The resulting spectra provide information about functional groups, classes of compounds, relationships between individual molecular parts, structural isomerisms and even the complete structure of compounds. ​ application areas applicable to all types of organic compounds including polymers Mixtures can be quantified and impurities detected Molecular spectroscopy (IR/Raman/ UV-Vis) In molecular spectroscopy, the incoming light is absorbed or scattered. This is characteristic of certain molecular fragments. The recorded spectra show specific bands for certain molecular components, which makes it particularly easy to identify organic materials. ​ application areas Analysis of organic components Polymer characterization Damage analysis Stains and dirt Analysis of competitive products X-ray fluorescence Analysis (RFA) The X-ray fluorescence spectrometer (XRF) provides the elemental composition of a sample and allows the detection of many elements in trace concentrations. The method is suitable for both solid and liquid samples. ​ application areas Trace analysis Testing materials for RoHS compliance (Restriction on Hazardous Substances) Atom- Emissions Spectroscopy (ICP-OES) ICP-OES allows the determination of elements in aqueous solutions by optical emission spectroscopy using inductively coupled plasma (argon). Due to the high plasma temperature (10,000 K), the compounds to be analyzed in the sucked-in sample aerosols are atomized and additionally ionized. In the process, the valence electrons are raised to a higher energy level. When returning to the ground state, the previously absorbed energy is emitted as specific light energy. The ion lines are evaluated because they are relatively insensitive to excitation disturbances. The advantages are better precision/reproducibility and detection limits. Simultaneous multi-element analysis of up to 70 elements is state of the art today. application areas Metal analysis Environmental analysis Electron microscopy (REM-EDX) The scanning electron microscope (SEM) is a device for imaging surface structures. It produces images with high resolution and depth of field. In addition, the distribution of different materials can be visualized. Energy dispersive X-ray spectroscopy (EDX) can also be used to analyze the local elemental composition of the different sample areas. application areas Structure and composition of components Damage analysis Stains and dirt Analysis of competitive products Surfaces- analytics (ESCA) Electron spectroscopy for chemical analysis (also XPS) analyzes (semiquantitatively) the elemental composition of the uppermost nanometers (10-15 atomic layers) of solids. ​ The method also provides information about the bonding states of the elements. The removal of the layers by sputtering allows the measurement of the depth distribution of elements (depth profile). ​ application areas Liability Wetting problems Paint peeling Surface and interface characterization Corrosion protection Reactivity of catalysts Do you have questions?

Mechanical tests Discover some of our methods. Tensile strength, flexural strength In a tensile test (destructive material testing) according to DIN EN ISO 527-1, the force and change in length of a sample are measured as a function of the applied elongation. This measurement can also be carried out at a defined temperature (-35 to +250°C). The tensile test is used to determine the modulus of elasticity, the tensile strength and the elongation at break of a material. Changes in these material properties after artificial aging or exposure to media are also interesting. In a bending test, the sample is subjected to quasi-static pressure. In the 3-point bending test according to DIN EN ISO 178, the test sample is positioned on two supports and loaded in the middle with a test stamp. Areas of application here include determining the bending modulus, the bending strength and more. Impact strength, notched impact strength In an impact test according to DIN EN ISO 179-1, the resistance of a material to impact (dynamic) stress is determined. In the notched bar impact test, the workpiece is notched before the test, which creates increased stress peaks at the notch. A pendulum hammer with a certain kinetic energy hits the back of the sample and breaks it. This test can also be carried out at defined temperatures. Low temperatures increase the brittleness of the material (cold brittleness). Printing forming residue The compression set is an important parameter for elastomers that are used as seals, for example. The test specimen is first compressed to a certain proportion of the thickness and fixed at a constant compression set. This state is maintained for a defined time, whereby additional influencing factors such as increased temperature can act on the test specimen. After the load is removed, the permanent deformation is measured. If the remaining compression deformation is too high, the seal's effectiveness could be limited. Tear strength In the tear propagation test, a defined defect is introduced into a test specimen, for example by means of a knife cut. The test specimen is then loaded at this point and the force measured as the crack propagates. The measured force provides information about the tear resistance of the material. The test is usually carried out according to DIN ISO 34-1 on elastomers for seals and according to DIN EN ISO 8067 on foams. ​ The tear resistance of film packaging is particularly important. The test according to ISO 34–1, ISO 6383–1, EN 495–2 and DIN 53363 simulates the film behavior when a package is opened. Ideally, the tear force and the tear force are the same - this allows a film bag to be opened in a controlled manner and the contents removed. If, however, the maximum force until the sample tears is relatively high, the tearing can suddenly continue after the first tear. For the end user, this usually leads to accidental spilling and thus often to a loss of the contents. In addition, the packaging becomes unusable and cannot be resealed. Adhesive strength and peel strength The peel strength, i.e. the resistance of a surface structure to detachment, is of particular interest for films, fleeces, carpets, upholstery fabrics and adhesive tapes. Depending on the application and test standard, the adhesive force can be peeled off at a peel angle of 180°, 90° or at any other angle. Similarly, roller devices can be used to maintain defined peel angles, for example in the roller peeling test according to DIN EN 1372 with a 90° peel angle or in DIN EN 1464 with a 60° peel angle.

Rely on our expertise and sophisticated methods to achieve the highest To ensure quality and precision in paint technology. Complete solutions for release testing from environmental simulation to damage analysis YOUR EXPERT Rainer Ziel Mail rainer.ziel@aso-labor.de phone +49 6022 81 2645 Test standards Initial sample testing according to automotive standards. Colour & Shine The assessment of color and gloss is often done visually by comparing it to a reference sample or standard. Correct lighting is crucial to detect additional irregularities such as blistering or paint peeling. Alternatively, color and gloss measuring devices enable the quantitative recording of color changes when changing batches or due to environmental influences. The measuring geometries used are standardized to ensure comparable results. Liability The cross-cut test evaluates the adhesion of paints to substrates and their resistance to damage. The painted surface is scratched in a cross shape and the adhesion is then checked using a peel test. The quality of adhesion is assessed according to the standards DIN EN ISO 2409 (GT0 to GT5) or ASTM D 3359-02 (5B to 0B). These paint adhesion tests (cross-cut and grid cut tests) are carried out both before and after climatic storage. Scratch test Scratch resistance tests, or scratch tests for short, are carried out on plastics to test the quality of the adhesion of paints and coatings to plastics. To do this, a needle is moved over the surface with increasing pressure and it is tested how long the surface can withstand this load. Environment- simulation and weathering The cross-cut test evaluates the adhesion of paints to substrates and their resistance to damage. The painted surface is scratched in a cross shape and the adhesion is then checked using a peel test. The quality of adhesion is assessed according to the standards DIN EN ISO 2409 (GT0 to GT5) or ASTM D 3359-02 (5B to 0B). These paint adhesion tests (cross-cut and grid cut tests) are carried out both before and after climatic storage. Chemical resistance During everyday use, paint comes into contact with a variety of chemicals. These are typically sweat, hand cream, sunscreen, various solvents, cleaning and disinfectants, and depending on the application, also cola or fuel. Chemical resistance is usually tested by direct contact with the test medium. The test may be made more stringent by simultaneous friction or temperature stress. The changes in the paint are evaluated according to specific criteria. Abrasion resistance, rub fastness or colour fastness Mechanical contact with a painted surface can lead to a change in the surface (abrasion). The Crockmeter test is a test procedure for painted surfaces that is common in the automotive industry. This abrasion test is based on the DIN EN ISO 105-X12 standard. At the end of the test, the fabric is visually examined for possible discoloration and the painted surface for premature wear. A crockmeter test is also suitable for simulating a combined effect of water or other media during mechanical resistance testing, thus significantly accelerating the aging of a surface. ​ Painted buttons or printed control elements, on the other hand, are preferably tested with an Abrex device. The actuation is simulated by a silicone finger with defined contact pressure and lateral displacement, whereby there is always a fresh friction fabric between the silicone finger and the surface to be tested. This fabric can also be exposed to a test medium. Rockfall testing The resistance of vehicle paintwork to stone chips is of particular interest to the automotive industry. In a stone chip test, sharp-edged impact bodies of a defined size and shape are fired at the paint surface using compressed air to simulate stone chipping. The type of impact body, the working pressure, the firing time and the angle of impact are specified in the relevant standards. The assessment of stone chip resistance is carried out by means of a visual comparison with images. Steam jet test The steam jet test according to DIN EN ISO 16925 is used to assess the adhesive strength of paints and coatings. For the test, the paint is first scratched or milled into the substrate in the shape of a St. Andrew's cross. The edges of the St. Andrew's cross are then treated with a pressurized water jet under defined conditions. The defect pattern after the steam jet test is assessed by comparing it with image panels showing different levels of damage. Salt spray testing The salt spray test according to DIN EN ISO 9227 is used for painted metal parts. It simulates both the influence of salty air near the sea and the stress on a component caused by road salt. A pH-neutral salt solution (NSS) is sprayed in a special chamber. This settles on the component and covers the surface with a corrosive salt water film. After the salt spray test, which lasts several days, the component is rinsed with distilled water to remove loose residues. It can then be checked whether the corrosion protection effect of a paint is fulfilled on all parts of a component or whether red rust is visible on the surface. The salt spray test is well suited to compare the corrosion protection effect of different protective coatings. Test standards Initial sample testing according to automotive standards. Blistering Bubbles or blisters, which are pronounced as local elevations, are often caused by inclusions in the paint layer. These inclusions can, for example, come from contamination on an unpainted component or from foreign materials in the paint system. Possible causes are unclean working conditions during painting or the inclusion of gases. For a precise analysis, the area usually has to be exposed by targeted preparation (cross-section). Subsequently, analysis techniques such as scanning electron microscopy (SEM-EDX) or microspectroscopic methods (IR / Raman) are used to precisely analyze the composition in the area of the unevenness. Paint craters Paint craters represent a local depression in the paint and are often a result of wetting problems. The paint is pushed outwards in the defect area and thus reduced in the crater area. The effect can range from a slight reduction in layer thickness to paint-free areas on the component surface. If the cause of the paint crater is a particle in the crater center, similar analyses are used as for bubbles . If no inclusions are visible, it is often still possible to analyze the paint crater. Release agents, grease or oils can often be detected on the paint surface using very surface-sensitive analysis methods. In addition, mechanical damage in the underlying paint layers (flaking) or in the unpainted component (dents or scratches) can also lead to paint craters. Paint adhesion problems Paint adhesion problems can be caused by contamination of the component surface, similar to wetting problems. Sometimes unsuitable paint systems are used which are not compatible with the material of the component. Many plastics require surface activation such as flame treatment, fluorination or plasma treatment. If this is not carried out properly, paint adhesion can also be reduced. Special surface analysis or paint analysis is required for analysis in order to be able to detect the usually thin changes to the surface or the boundary layer. Chalking Chalking is a form of damage to paints caused by aging or external chemical influences. Pigment and filler particles are exposed in the area close to the surface due to the degradation of the paint's organic binding agent. The increased light reflection on the rougher surface creates a brighter and more matte appearance. Chalking must be distinguished from the fading of pigment particles, which has very different causes. Do you have questions?
