  • Publication number: 20230287173
    Abstract: The present invention is directed to non-aqueous, curable film-forming compositions comprising: a) an anhydride functional compound; b) at least one of: (i) a hydroxyl functional compound having at least two hydroxyl functional groups and (ii) a carbodiimide functional compound; and c) hydrolyzable functional groups. After application of the curable film-forming composition to a substrate to form a coated substrate, and upon subjecting the coated substrate to curing conditions, the curable film-forming composition undergoes multiple cure reactions. The present invention is further directed to methods of preparing coated substrates with these compositions.

  • Publication number: 20220276191
    Abstract: A radio frequency signaling system includes a curable coating composition configured to be cured to form a cured coating and a sensor received in the curable coating composition. The sensor includes circuitry forming an inductor-capacitor circuit. The circuitry has a maximum outer diameter of 10 ?m-2.0 mm. The circuitry is configured to generate an electromagnetic field in response to an external radio frequency signal. A container configured to be monitored by a radio frequency signaling system is also provided. The container includes: a container body having an outer surface and an inner surface; a cured coating on the inner surface and/or the outer surface of the container body; and a sensor positioned in the cured coating configured to detect absorption of a fluid contained in the container body by the cured coating.
