Enhancing biocides in coatings: Antimicrobial peptides Academic Article uri icon

abstract

  • In the July 2006 issue of PCI, "Next-Generation Antimicrobial Additives for Reactive Surface Coatings," the theoretical background for the use of antimicrobial peptides in coatings was discussed. Biocides for protective, decorative or functional coatings are typically divided into three main categories, in-can stabilizers, post-application films or substrate preservers. Conventional biocide technology is based upon type of targeted microorganism (bacteria, yeasts, molds and mildews, algae, and spore-forms of certain of these microorganisms). Chemistries used for in-can stabilization are mainly isothiazolones and formaldehyde donors. Substrate and film preservation are accomplished through chemistries such as chlorothalonil, iodopropynylbutylcarbamate, octylisothiazalone and zinc pyrithione. The hurdles for biocide manufacturers are mainly regulatory in nature, as many biocides are considered toxic or persistent in the environment. Additionally, microorganisms that are prevalent in coatings persistently breakdown polymeric binders and are continuously adapting to achieve resistance to conventional biocides.
