| abstract |
A coating composition contains an effective amount of between 5 and 70 percent by weight of metalized tubules which are or which encapsulate a composition known to have an antifouling effect or known to possess antimicrobial, herbicidal algaicidal or pesticidal (biocidal) properties. When the coating composition is applied to a surface to be protected, a toxic surface environment is formed. The tubules can be used alone or the tubules can contain in the hollow core a secondary or co-biocidal agent or mixtures of these agents. When desired, the metal coating layer metalizing the tubule can be a non-biocidal metal. In those cases, protection is provided by the biocidal agent carried in the core. |
