• Electrostatic principle states like charges repel and unlike charges attract
• The electrostatic field created by ECT's high voltage charge causes oil at the edge of the blade to separate into small streams. Since the charged streams cannot absorb the electrostatic charge, they immediately burst into small particles
• These particles form an evenly dispersed spray pattern, which is uniformly drawn to the grounded substrate
• At the same time, the moving strip is grounded ensuring opposite charge
• The oil particles then adhere to the moving strip giving the uniform coating

Advantages over Mechanical Coating Methods

• Eliminate rust claims
• No telegraphing of impurities to the strip
• No replacement of solid - or rag-rolls
• Minimal preventative maintenance
• Fast change-over of different oil
