Standard: ASTM G8 Cathodic Disbondment

A coating material is exposed to electrical stress in a highly conductive, alkaline electrolyte. Electrical stress is applied by means of a sacrificial magnesium anode or from an impressed current. The coating is perforated before the test, and after the specified time, a physical examination is carried out to determine any loss of adhesion. This procedure forms an essential part of comprehensive Product Testing to ensure coating durability and performance under harsh conditions.
