Anode Cells for Electrophoretic Coating Systems

Overview
Anode Cells, also known as Anolyte Cells, are essential components in cathodic electrophoretic coating (e-coating) systems. They serve to isolate the anode from the paint bath while allowing ion exchange through a selective membrane. This separation helps maintain bath consistency and enhances the overall coating quality.

Working Principle

• Each Anode Cell is made up of a corrosion-resistant stainless steel anode encased in an ion exchange membrane. During e-coating, under DC voltage, positively charged ions (such as amines or contaminants) migrate through the membrane into the anolyte solution. This process:
• Helps control the pH balance in the bath
• Improves paint stability and life span
• Reduces contamination and coating defects

Specifications

Key Features

• High-performance ion-exchange membrane with excellent chemical resistance
• Integrated high-strength porous support for structural integrity
• Stainless steel electrode for durability and corrosion resistance
• Leak-proof design to avoid paint contamination
• Efficient anolyte circulation system to aid in heat dissipation and ion removal

Advantages

• High-quality anion exchange membrane for superior ion selectivity
• More open area = lower resistance = better current efficiency
