Professional-grade vinyl paint masking tape with natural rubber adhesive for high-temperature applications up to 300°F. Features excellent conformability for curved surfaces, clean removal, and sharp paint lines for automotive, aerospace, and industrial masking.
Scotch® High Temperature Fine Line Tape 4737TL is a premium vinyl paint masking tape specifically engineered for demanding industrial applications requiring precise paint lines and excellent color separation. This professional-grade tape features a natural rubber, pressure-sensitive adhesive that holds reliably to surface contours, making it ideal for complex shapes and curved surfaces. The smooth vinyl backing provides superior conformability while resisting lifting around corners and in depressed areas, ensuring clean, sharp paint lines even on molded and curved surfaces.
Designed to withstand extreme heat conditions, this tape delivers optimal performance in temperatures as high as 300°F (149°C) for up to 30 minutes, making it perfect for high-temperature bake cycles in automotive, aerospace, rail, and marine paint processes. The 83 lb. die-cuttable poly-coated kraft (PCK) liner allows the tape to lay flat despite humidity changes, preventing curling and maintaining form for rotary die cuts, flatbed die cuts, and plotter-cut applications. It removes cleanly after bake cycles with minimal adhesive residue, helping to save production time and reduce cleanup costs.
This tape is recommended for specialty vehicle masking, automotive fascia applications, two-tone and multiple-color paint jobs, and any industrial paint masking application where critical paint break lines are essential. Available in translucent blue with a liner configuration, it is designed for indoor use only and is intended for industrial/occupational use by trained professionals, not for consumer use.
