Tests to evaluate surface textures and deffects in coatings

Category: Quality control of polymers and plastic products

The texture is a surface property of a piece which can be felt when touching and seeing, so it affects to aesthetics. They are repetitive or random alterations of the piece’s nominal surface. The most usual properties that can characterize it are roughness and wavyness.

Surface defects

Any defect and contamination that is produced when the film is being formed will affect the final aspect and the coating protective properties. Therefore, it is important to detect them by visual inspection of the surface or by means of a surface analysis with a magnifying glass or a microscope. AIMPLAS has light and scanning microscopes that allow to carry out comprehensive analysis of the surfaces.
