Professional black polyester splicing tape with aggressive rubber adhesive for photographic film processing. Offers excellent chemical resistance, temperature stability from -60°F to 300°F, and automatic sensor compatibility. 1 inch x 72 yard rolls, 36 per case.
3M™ Photo Film Splicing Tape 8422 is a professional-grade black splicing tape specifically designed for photographic film processing and web processing applications. Featuring a thin yet durable polyester backing with an aggressive rubber adhesive, this tape delivers exceptional performance in demanding industrial environments. The tape's black opaque backing is specifically engineered to work seamlessly with automatic sensors and equipment, enabling reliable splice identification during processing.
The aggressive rubber adhesive formulation provides high tack and excellent chemical resistance, making it ideal for splicing most photographic films through developing chemicals and other harsh processing solutions. The tape maintains flexibility at temperatures as low as -60°F (-50°C) while remaining dimensionally stable up to 300°F (150°C), ensuring consistent performance across a wide temperature range. With outstanding solvent and chemical resistance properties, this tape excels in photographic processing environments where exposure to various chemicals is inevitable.
Each case contains 36 rolls of tape, each measuring 1 inch wide by 72 yards long with a 2.5 mil total thickness. The single-sided adhesive design provides 50 oz/in adhesion strength (54 N/100mm), offering superior holding power for demanding splicing applications. This product is intended for industrial and occupational use only, meeting professional standards for print and general industrial applications.
