Ideal for splicing most film for processing through the developing chemicals. Rubber Adhesive Offers High Tack with Excellent Chemical Resistance The durable backing of 3M Photo Film Splicing Tape 8422 is ideal for splicing most film for web and photo processing. The black opaque backing allows for splice identification with automatic sensors and equipment. In addition, the polyester provides additional abrasion protection for sealing, edging and Colour-coding. The rubber adhesive sticks well to a variety of films, offers excellent chemical and solvent resistance, and features high shear strength. The tape remains flexible at -60°F (-50°C) and is dimensionally stable up to 300°F (150°C). Recommended Applications: – Splicing of most photographic film through the chemical developing process – General wide web splicing, including butt splicing and core starting – Sealing, Colour-coding, protecting and edging where a higher tack rubber adhesive is needed – Splicing applications with automatic sensors and equipment – Defect marking
