  • Patent number: 11760897
    Abstract: Solvent-borne coating compositions and methods for forming coated substrates are provided. In one example, a solvent-borne coating composition includes a solvent(s), a colorant(s), a binder including one or more resins, a sag control agent, and a wax dispersion. The sag control agent includes urea crystals that are present in an amount of from about 0.5 wt. % to about 6 wt. % based on the weight of the binder. The wax dispersion includes ethylene vinyl acetate-based wax particles present in an amount of from about 3 wt. % to about 8 wt. % based on the weight of the binder. The solvent-borne coating composition has a non-volatile content of from about 11 to about 30 vol. % based on the volume of the solvent-borne coating composition.
