Abstract
This invention provides for a curable antimicrobial coating system comprising a base coating composition and a top coat coating composition wherein each contains and antimicrobial agent. The base coat forms a non-hydrophilic polymer layer and the top coat preferably forms a hydrophilic polymer layer or a non-hydrophilic polymer layer which does not preclude the release of the antimicrobial agent. This two-layer coating is especially designed for erosive environments and provides continual antimicrobial activity regardless of the stage of wear or erosion.
