  • Patent number: 12338366
    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.
    Type: Grant

  • Patent number: 9751971
    Abstract: A dispersing resin for conventional solventborne pigment preparations having a low to very low proportion of volatile organic substances is provided. Further provided are solventborne coating materials containing the dispersing resin. Uses include paints, varnishes, adhesives, inks or printing inks, and compositions for coloring of plastics. The pigment preparations produced with these resins are free of yellowing, stable to weathering, of low viscosity and intensely colored.
