3M Anodizing Masking Tape 8985L Violet

• Specially developed for masking workpieces in chromic acid anodizing baths (Type I)
• Transparent violet adhesive tape for fast, easy, and precise positioning
• Provides clean masking edges and minimizes paint bleed to reduce post-processing of parts
• Clean, one-piece removal after processing
• The silicone-free formulation reduces coating and bonding defects after the process
• Faster masking and demasking than with liquid masking agents; no curing time
• Includes release liner for printing and die-cutting

3M™ Anodizing Masking Tape 8985L is a reliable, silicone-free solution for chromic acid anodizing (Type I). This high-performance tape is highly resistant to chromic acid and produces sharp masking edges. Thanks to its rubber-resin adhesive, it is easy to remove.

The durable polyester backing ensures that chromic acid anodizing baths (Type 1) cannot damage 3M™ Anodizing Masking Tape 8985L. The silicone-free rubber-resin adhesive minimizes the risk of silicone contamination, which could negatively affect subsequent processes such as bonding or painting. The tape creates sharp masking edges, minimizes paint bleed and rework, and can be used with or without a chemical film on a wide variety of aluminum and other metal alloys. 3M™ Anodizing Masking Tape 8985L is suitable as a replacement for complicated and messy liquid masking methods that produce unpleasant odors. The transparent tape is easy to position and requires fewer steps. Unlike liquid masking, there is no waiting time for curing, so masking and demasking can be performed more quickly. It is easy to use and can be removed cleanly in one piece at the end. The violet transparent tape is rolled onto a clearly visible printed backing; the release liner facilitates die-cutting.
