Anodizing Masking Tape
3M™ Anodization Masking Tape 8985L is a reliable non-silicone solution for Type I (chromic acid) anodization. Designed for performance, it is specifically resistant to chromic acid and provides sharp lines with a rubber adhesive for easy removal. This tape can mask and de-mask up to 5x faster* than labor-intensive liquid masking for improved productivity.
Engineered Specifically for Resistance to Chromic Acid 3M™ Anodization Masking Tape 8985L has a tough polyester carrier to stand up to chromic acid anodization baths (Type I anodization). It also features a non-silicone rubber adhesive to minimize the risk of silicone contamination that could impact downstream processes such as bonding or paint adhesion. This tape provides sharp masking edges, minimizing leakage and the need for rework, and can be used with or without chemical film on a variety of aluminum and other metal alloys.
3M™ Anodization Masking Tape 8985L can replace complex, messy liquid masking and the unpleasant odors involved. The transparent tape is easy to position and can be applied in fewer steps; it also eliminates the cure time of a liquid so that overall masking and de-masking can be accomplished up to five times faster*. Ease of application and clean, one-piece removal mean users could save up to 60%* on labor time and associated costs. This tape is transparent purple with a printed backing for visibility and has a liner for easy die-cutting.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.
It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.
Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.
Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
