Anodization Masking Tape 8985L

• Designed specifically for masking in chromic acid (Type I) anodization baths
• Liner provides added stability for easy die-cutting
• Masks and de-masks up to 5x faster* than liquid masking, with no cure time
• Non-silicone formulation helps reduce post-process coating and bonding failures
• Polyester backing with rubber adhesive and film liner
• Provides sharp masking lines and minimizes leaking to reduce the need for part rework
• Transparent purple tape for fast, accurate positioning and easy identification

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.

*Up to 5x faster and up to 60% reduction in labor time both based on 3M internal data.
