Is my coating system good for Cathodic Protection?
This mainly depended on the amount of electrons that can be passed through the coating system. This is defined as electrical conductivity. A coating systems that has a very high (electrical) resistance can be defined as an isolating coating system. Examples are asphalt/bitumen and polyethylene (PE) based coatings. On the other hand, there are coating […]
Is surface preparation important before coating application?
Yes, Surface preparation of the steel before external coating application is the foundation of any corrosion control program. Any compromise made in the degree of surface preparation will affect coating performance regardless of how high the technical quality of the coating is. Rule of thumb An important rule to remember is when selection both the […]
