Abstract
A material coating system for an apparatus having a housing configured to contain a fluid is disclosed herein. A multi-layer coating is applied to the housing to mitigate damage caused by external factors. The multi-layer coating includes: a layer of a primer coating having anti-corrosive properties, a layer of a mid coating having mechanical and chemical properties capable of at least partially closing a hole in the housing to avoid fluid leakage and optionally a layer of a top coating having properties that resist ultraviolet radiation from passing therethrough.
Claims35
A system comprising:
- an apparatus including a housing configured to contain a fluid;
- a multi-layer coating applied to the housing;
- wherein the multi-layer coating includes:
- a layer of a primer coating;
- a layer of a mid coating including mechanical and chemical properties capable of at least partially closing a hole in the housing;
- and
- a layer of a top coating including properties that resist ultraviolet radiation from passing therethrough.
An apparatus comprising:
- a housing configured to hold a fluid;
- a coating applied to an outer wall of the housing;
- wherein the coating includes a primer layer applied to the outer wall and a polyurea mid coat layer applied over the primer layer.
A method comprising:
- at least partially filling a housing with a fluid;
- applying a primer coating layer to an outer surface of the housing;
- applying a mid coating layer to the primer coating layer;
- applying a top coating layer to the mid coating layer;
- wherein the primer coating layer includes corrosion inhibitors, the mid coating layer includes mechanical properties to prevent fluid leakage through a hole of up to approximately 12.7 mm, and the top coating includes UV resistant properties.
