2) Visual Coating Uniformity, Color and Scratch
3) Coating adhesion
Three Steps
First, feeling the surface of tubular anodes in a pair of white gloves to observe
whether black mark is left on the gloves
Second, paste with transparent tape to observe whether black mark is left on the
Tape
Third, bend the ribbon to observe whether the coating fades
