Is it possible that use of a protection system of impressed current will cause paint to peel off?
RESPUESTA 11: It is impossible for this to occur with systems that use pre-programmed currents for port or navigation. This is because the system calculates values that are never to pass below -1100mV either in port or under navigation. Given that the limit for paints is above -3000mV, the possibility of paint peeling or falling off because of the system is null. Additionally the Proytec system uses DC power and high tech equipment in order to ensure the least amount of battery drain. The system uses minimal power, under 3 volts, and even if someone were to turn the system to full power, it would barely reach -1200mV. This value is still way below the limit that would cause the paint to peel. QUESTION 12: I have a steel-hulled boat that has bubbles in the paint and water appears when I pinch them. In spite of the bubbles with water there is no visible indication of corrosion. Are these bubbles due to cathodic protection? ANSWER 12: No. Cathodic protection with sacrificial anodes makes
