Abstract
A method for coating a valve assembly including: providing a valve assembly including a metal susceptible to corrosion; cleaning an outside surface of the valve assembly; preparing a zinc primer by adding an anti-microbial agent to provide an anti-microbial zinc primer; applying a first layer of the anti-microbial zinc primer to the outside surface of the valve assembly; and applying a second layer over the first layer, the second layer including a topcoat for a two-layer coat; and curing the two-layer coat by heating the valve assembly. A valve assembly with protection layers including anticorrosion and antimicrobial protection is also described.
Claims19
A method for coating a valve assembly comprising:
- providing a valve assembly comprising a metal surface susceptible to corrosion;
- cleaning an outside surface of said valve assembly;
- adding an anti-microbial agent to a primer material comprising a zinc component to provide an anti-microbial zinc primer, the anti-microbial agent being different from the zinc component;
- applying a first layer of said anti-microbial zinc primer to said outside surface of said valve assembly;
- applying a second layer over the said first layer, said second layer consisting of an epoxy topcoat for a two-coat layer;
- and
- curing said two-layer coat by heating said valve assembly.
A method, comprising:
- applying a primer layer to an exposed surface of a valve assembly, the exposed surface being disposed along a flow path through which a fluid traverses the valve assembly, the primer layer comprising a zinc component and at least one anti-microbial agent;
- applying a second layer on the primer layer, said second layer consisting of an epoxy topcoat;
- and
- curing at least the second layer,
- wherein the at least one antimicrobial agent is different from the zinc component.
