In automotive refinishing, repair, and OEM masking processes, masking tapes are often exposed to sunlight and outdoor conditions for extended periods. When applications require 3 to 15 days of exposure, UV resistance becomes a critical performance factor that directly affects surface quality and process efficiency.

Masking tapes with insufficient UV resistance may degrade under prolonged sunlight and heat. In real automotive environments, this can lead to several application issues, including adhesive residue after removal, tape tearing, and difficulty during peel-off. As the adhesive system ages, edge adhesion may also weaken, causing lifted edges and paint bleeding, which results in unclear paint lines and costly rework.

Beyond removal issues, prolonged UV exposure can affect the paper backing itself. Reduced flexibility and paper brittleness may cause the tape to break during removal or leave paper fragments on painted or plastic surfaces. In some cases, surface marks or shadow impressions may appear after tape removal, especially on dark or freshly painted automotive finishes.

In automotive masking, UV resistance is not simply about withstanding sunlight. It refers to the tape’s ability to maintain stable adhesion, clean removability, and consistent masking performance throughout the entire exposure period. This stability is essential for protecting vehicle surfaces and ensuring professional-quality results.

To address these application demands, MT 613Y automotive masking tape is designed with a high-quality washi paper backing and a specially formulated adhesive system. It offers up to 15 days of UV resistance, enabling clean removal without residue even after extended outdoor exposure. Its excellent conformability allows reliable masking on curves, contours, and complex automotive surfaces, while maintaining sharp and clean paint lines.

As automotive applications continue to demand higher efficiency and surface quality, selecting a UV-resistant masking tape helps reduce rework, improve productivity, and ensure consistent results. MT 613Y provides a practical solution for professionals seeking reliable masking performance under real-world UV exposure conditions.
