Abstract:
Embodiments described herein provide a coating composition including an aqueous acrylic/polyurethane dispersion. The aqueous acrylic/polyurethane dispersion is produced from at least one isocyanate component, a polyol mixture, and at least one acrylate solvent. The polyol mixture includes a polyester polyol and at least two different oleo-based polyols. The coating composition exhibits improved chemical resistance without sacrificing other properties, such as hardness and abrasion resistance.
