Characteristics
Processing & delivery
- Slitting to confirmed widths, with width tolerance stated on the drawing
- Die-cut and kiss-cut conversion against drawing or sample
- Roll, sheet, or project-kit packaging with batch and drawing labels
Selection boundaries
- Adhesion depends on substrate, surface energy, cleaning, contact pressure, dwell time and temperature.
- Published ranges describe the construction, not a guaranteed installed performance for every surface.
- Electrical, flame, automotive and food-contact claims require the specific approval file for the ordered lot.
