Professional-grade high-temperature paint masking tape with vinyl backing, natural rubber adhesive, and superior conformability for sharp paint lines and color separation in automotive, aerospace, and specialty manufacturing applications.
Scotch® High Temperature Fine Line Tape 4737SL is a premium industrial paint masking tape engineered for professional-grade applications requiring sharp paint lines and excellent color separation. This specialized tape features a natural rubber, pressure-sensitive adhesive combined with a smooth vinyl backing that delivers exceptional conformability to complex shapes, curved surfaces, and recessed objects. The tape is specifically designed for high-temperature paint processes, withstanding temperatures up to 300°F (149°C) for up to 30 minutes, making it ideal for modern automotive, aerospace, rail, marine, and specialty vehicle manufacturing environments.
The 4737SL variant includes an 83 lb. die-cuttable poly-coated kraft (PCK) liner that enables flat laying despite humidity changes, preventing curling and maintaining form for rotary die cuts, flatbed die cuts, and plotter-cut stencils. Its advanced vinyl backing provides superior heat resistance and enables easy one-piece removal to minimize production time and adhesive residue. The tape resists lifting around corners and in depressed areas, ensuring clean paint breaks and professional color separation in multi-color and two-tone applications.
This industrial-grade masking tape is recommended for automotive fascia masking, specialty vehicle paint jobs, custom applications, and any paint masking scenario requiring critical paint break lines. The blue translucent color provides excellent visibility during application while maintaining the professional finish required in high-end manufacturing. As a recognized leader in industrial adhesive solutions, 3M has developed this conformable fine-line tape to meet the most demanding paint masking requirements across multiple industries.
