# §195.559. What coating material may I use for external corrosion control?


Coating material for external corrosion control under [§ 195.557](/cfr/49/195.557.md) must—

- (a) Be designed to mitigate corrosion of the buried or submerged pipeline;
- (b) Have sufficient adhesion to the metal surface to prevent under film migration of moisture;
- (c) Be sufficiently ductile to resist cracking;
- (d) Have enough strength to resist damage due to handling and soil stress;
- (e) Support any supplemental cathodic protection; and
- (f) If the coating is an insulating type, have low moisture absorption and provide high electrical resistance.
