Abstract
Improved powder coatings exhibit enhanced resistance to bacterial and fungal attack, while possessing excellent toughness, appearance, corrosion resistance, durability, processability, and ease of application. The coating is comprised of anti-microbial agents melt-processed into the matrices of powder coatings. An article may be coated with a thermoset or thermoplastic powder which may be applied by electrostatic spray, by dipping it into a fluidized bed (or electrostatically charging it and then dipping it into the fluidized bed), or by thermal or flame spray.
