• Non-combustible and non-toxic


• Excellent adhesion and durability


• Efficient process flow for metal surfaces

Process Flow:

1. Pre-cleaning


2. Oil removal


3. Washing


4. Rust removal


5. Neutralization


6. Phosphating


7. Passivation


8. Electrophoretic coating


9. Ultra-filtration


10. Drying
