MMO Wire Anode
※ MMO Wire Anode are manufactured using solid titanium, which meets ASTM B863 Grade 1 or Grade 2 standards, which has been coated with Taijin Mixed Metal Oxide coating. The mixed metal oxide is a crystalline, electrically conductive coating that activates the titanium and enables it to function as an anode.

5) QUALITY CONTROL
Strict quality procedures are followed throughout the whole process from raw materials to finished products to ensure coating adhesion and loading.
a) Chemical Composition- ASTM B863 Gr1
b) Visual Coating Uniformity, Color and Scratch
c) 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 wire to observe whether the coating fades
d) Accelerate Life Test
NACE standard TM0108-2008, 20000A/m2, 1mol/l Na2SO4, Accelerated Life Test Failure time: 35-40 days
