EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and rapid testing services within the scope of the GMW 14698 test. This standard specifies a test method for determining the resistance of organic coatings that can be used on one or more metal or metal layers.
In the automotive industry, coatings are often applied to the substrate to protect the surface. Coatings also affect the appearance of the substrate in terms of gloss and color. Small particles not only reduce the beauty of the surface of the coated product, but also cause premature degradation of the substrate. Cracks and reduced surface beauty are easy to visually recognize. In contrast, the relationship between scratch resistance, scratch resistance, chemical composition, and adhesion is more complex.
Scratch resistance has no precise definition and is difficult to measure. Different terminologies are used, from degradation of light damage to friction, wear, erosion and breakage of mechanical defects. For example, resistance to scratches, reduced gloss, turbidity, increased deformation, resistance to warping, thinning or changing the color of the substrate.
The relationship between curvature and the properties of both the drawn surface and the coated substrate is complex. Support for various editing methods determines the overall shape, size and shape of the remaining content. Three types of deformation can cause cracking: elastic, ductile, and brittle.
The deformation response is dependent on both the interaction and the conditions. In order for the coating to stay on the surface, consistency in the stack and good adhesion of the substrate is required. The resulting structure is determined by the time-dependent properties of the polymer. That's why temperature and starting point are very important when it comes to polymeric materials. Available testing methods differ in many ways and compare results.
