  • Patent number: 11566139
    Abstract: The present invention is directed to coated articles demonstrating a transmission of electromagnetic radiation having a frequency of 22 to 81 GHz in the range of 70% to 100%. The articles comprise substrates coated with curable film-forming compositions comprising a first film-forming polymer prepared from at least one hydrophobic monomer, a second film-forming polymer prepared from at least one hydrophobic monomer, and a curing agent. Upon application of the curable film-forming composition to the substrate to form a coating layer, the first film-forming polymer is distributed throughout the coating layer, and the concentration of the second film-forming polymer is greater at the surface of the coating layer than the concentration of the second film-forming polymer within the bulk of the coating layer. The present invention is also drawn to methods of mitigating contaminant build-up on a substrate using the curable film-forming compositions described above.

  • Publication number: 20220220336
    Abstract: A multilayer coated substrate is disclosed, comprising: (a) a cured basecoat layer formed from a curable basecoat layer comprising a color-imparting, pigment-containing basecoat composition applied directly to a cured electrodeposited primer coating without application of an intermediate primer surfacer coating, and (b) a curable unpigmented coating composition applied to the cured basecoat layer to form a clear or transparent coating layer over the cured basecoat layer. The cured electrodeposited primer coating is adhered to the substrate. The basecoat layer is deposited from a curable aqueous composition comprising: (i) a continuous phase comprising water, and (ii) a dispersed phase comprising: (A) polymeric particles containing carboxylic acid functionality; and (B) a polycarbodiimide. The polymeric particles are prepared by polymerization of a mixture of ethylenically unsaturated compounds, including a multi-ethylenically unsaturated monomer.
