Paint Finish Process

The Power Partners factory utilizes a paint finish process called "2CEC", a trademark for a two-coat cathodic electrodeposition paint process.  This new advanced coating technique maintains the structural integrity of transformers that are subjected to the long-term corrosive environments of coastal areas and industrial contaminants.  

Paint Process

Cathodic electrodeposition of paint occurs when direct current is applied to positively charged resin micelles dispersed in water.  The resin micelles migrate toward the cathode (transformer tank) and are deposited in a process known as electrophoresis.  As the process continues, the thickness of the deposit builds, resistance increases, and the film reaches a thickness limit.  The most accessible areas are coated first, but as the resistance increases, less accessible areas coat, producing a highly uniform film build.  Two-coat cathodic electrodesposition is the application of two coats of paint (epoxy primer/acrylic urethane topcoat).

Advantages of the Process

1. Complete and uniform coverage of complex shapes, including edges and corners, hanger brackets, ground pads, and tank bottoms.
2. Access into partially closed areas, such as inside the hanger brackets.
3. High solids film eliminates sagging problems.
4. Minimal organic solvent content.
