Premium high-temperature fine line masking tape for automotive and aerospace applications, featuring clean removal, solventless adhesive, and exceptional conformability for two-tone paint applications.
Scotch® High Performance Fine Line Tape 4740 is a premium pressure-sensitive, solventless adhesive tape engineered specifically for two-tone paint applications in automotive OEM, specialty vehicle, and aerospace markets. With exceptional high-temperature resistance, this tape operates reliably at temperatures as high as 320°F (160°C) for up to 60 minutes and 356°F (180°C) for up to 10 minutes, making it ideal for multiple paint-bake cycles. The tape features a 5.2 mil thickness and is constructed with a polyolefin film backing and clear acrylic adhesive that provides superior conformability to complex surfaces including steel, intricate patterns, depressed areas, and sharp curves.
Designed for precision masking applications, this fine line tape delivers professional and consistent paint lines while removing cleanly with zero edge residue or ghosting. The water-based, solventless adhesive technology reduces solvent usage by 80% compared to similar 3M solvent-based alternatives, making it an environmentally conscious choice without compromising performance. The tape's exceptional conformability ensures instant and secure adhesion even on irregular surfaces, resisting lifting during critical paint operations. Available in 12mm width with 50-meter length rolls packaged in convenient 100-roll cases, this product meets the demands of challenging automotive fascia painting, custom two-tone applications, and other critical masking requirements.
3M's science-based approach to adhesive tape technology has resulted in a product that effectively addresses common industry challenges such as low-quality paint lines, slivering, paint flaking, and adhesive residue. The Scotch® High Performance Fine Line Tape 4740 helps reduce inefficiencies and rework costs caused by poor tape performance, delivering reliable results that meet strict productivity goals in professional masking applications.
