ABSTRACT
Microorganisms are ubiquitous in the environment. Many of them have simple requirements for growth that can be met by most waterborne coatings. Adding an in-can preservative will protect these coatings in the wet state during storage and transport. After a coating has been applied and dried, most waterborne and solvent-borne coatings are susceptible to colonization by fungi or algae. The addition of a dry-film preservative (fungicide or algaecide) will ensure long-term performance of the coating.
