Green polyester masking tape is a widely used material for achieving complete anodizing stop-off.
It cuts easily, adheres quickly and removes cleanly.
It is a masking tape that easily withstands the Type 2 and Type 3 anodizing processes (for a Type 1 anodizing masking tape, see here).
One thing to remember
For the best results, it is important to remember that anodizing changes the surface of aluminum and tapes are pressure sensitive.
So be certain to both push down on the tape after applying, and then give the tape some time (ideally 12 to 24 hours) before anodizing.
Quality
Our American made tape means the same-day trip from manufacturer to our dock ensures fresh, USA-quality tape that will last up to 12 months without degrading in effectiveness.
Just store on end in a cool, humidity-controlled location between 60F and 80F for best shelf life.

And with Viadon, you are not limited to a handful of tape widths.
