  • 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.

  • Publication number: 20220041887
    Abstract: A formulation contains a curable composition having component A, component B, component C, and component D. Component A may have at least one polysiloxane. Component B may have at least one polyether bearing silyl groups and/or reaction products of a polyether bearing silyl groups with one or more isocyanate-containing compounds. Component C may have at least one catalyst. Component D may have at least one epoxy-functional compound and/or one amino-functional compound.
