3M 7100207280 | 8985L 72 yd x 1.000" Width x 3.9 mil Thickness Specialty Application 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.

• 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. This tape is transparent purple with a printed backing for visibility and has a liner for easy die-cutting.
