The criteria for successful "splash zone” protection consists of the following requirements:
Metal surface isolation – metal must be isolated and separated from the environment, such as with materials with properties similar to rubber or polyurethane
High electrical resistance – coating should inhibit electrolytic corrosion and resist electrical current flow
High impact resistance – protects against and resists buffeting from boats and floating debris
Flexible – won't crack under the distortion of pipe bends or twists
Bio-fouling resistant– isolate metal from sea life, fungus and scale attack
Good thermal insulation – important in the case of flow lines
Guaranteed for life – should last virtually the life of the installation
