Highlights
- Built for masking in chromic acid (Type I) anodization baths
- Masks and de-masks faster than liquid masking — without the cure time
- Transparent backing helps make for fast and accurate positioning
- Helps ensure sharp masking lines and prevent leaking to reduce the need for rework
- Non-silicone formulation helps reduce post-process coating and bonding failures
- Polyester backing uses a rubber adhesive and a film liner for added stability when die-cutting
3M™ Anodization Masking Tape is a reliable, non-silicone solution for Type I (chromic acid) anodization. As an alternative to complex and messy liquid masking, this tape helps provide sharp edges that minimize leakage and the need for rework — all in a fraction of the time and effort. Mask and de-mask without the curing time, or the unpleasant odour, by using 3M™ Anodization Masking Tape.
When working with aluminum or other alloys, accurate placement is an integral part of the anodization masking process. The transparent backing of 3M™ Anodization Masking Tape helps make application seamless and exact, while its strength enables a clean, one-piece removal when demasking. This tape also comes equipped with a film liner that adds stability for easy die-cutting when custom shapes are needed. Use 3M™ Anodization Masking Tape for your next job and reimagine the way you mask.
