  • Publication number: 20230304940
    Abstract: The invention relates to a method for inspecting a coated surface for a surface defect. The method comprises: using (102) a device (200, 300, 400, 700, 800, 900) for covering the coated surface to be inspected, the device being configured to create an enclosed space to isolate the surface coating to be inspected from ambient illumination in order to provide predefined photographic acquisition conditions within the enclosed space; acquiring (104) a photo of the coated surface being within the enclosed space; and inspecting (106) the photo for the presence of the surface defect.

  • Publication number: 20220186048
    Abstract: Rhamnolipids and/or sophorolipids can be used in coating compositions for improvement of the speed of wetting of pulverulent formulation constituents in such compositions, which leads to a reduction in dust nuisance during incorporation thereof and to the increase in occupational safety in the production of coating compositions. Rhamnolipids and/or sophorolipids can also be used in coating compositions for obtaining improved homogeneous colour appearance of the dry paint film with regard to difference in hue, ascertained from the delta E and visual assessment.
