Abstract:

A coating composition includes: (a) a carboxylic acid functional polyol polymer; (b) a melamine-formaldehyde crosslinker reactive with the carboxylic acid functional polyol polymer; (c) an acid catalyst; and (d) a non-aqueous liquid medium. The carboxylic acid functional polyol polymer has an acid value within a range of from 30 to 120 mg KOH/g and a hydroxyl value within a range of from 60 to 150 mg KOH/g. The melamine-formaldehyde crosslinker includes imino and methylol groups that together make up 35 mole % or less of the total functionality of the melamine-formaldehyde crosslinker, and butyl groups and isobutyl groups that together make up 5 mole % or greater of the total functionality of the melamine-formaldehyde crosslinker. The coating composition cures at a temperature of 100 C. or less.

International Classification:

H04B 1/03
C09D 133/10

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.
