Answer:
The 983-326 uses microprismatic retroreflective lens technology that maintains high visibility at wide entrance angles up to nearly 90 degrees. It features a non-metallic construction to eliminate corrosion risk, pre-sealed edges, and a solvent-free pressure-sensitive adhesive.
3M 983-326 Diamond Grade conspicuity tape is engineered for demanding transport and heavy industrial fleet environments. Key differentiating construction characteristics include:
- Microprismatic Optical Structure: Employs synthetic resin microprisms that reflect light back to oncoming headlamps across wide entrance angles approaching 90 degrees, offering superior nighttime visibility compared to glass-bead tapes.
- Non-Metallic Build: Built entirely without aluminum metallization layers, making it completely non-corrosive when applied to metal panels or washed with fleet detergents.
- Pre-Sealed Edges: Edge seals applied during manufacture protect internal prisms from water penetration, road grime, and edge delamination.
- Industrial Pressure-Sensitive Adhesive: Uses an aggressive, solvent-free adhesive with a clear protective liner designed for long-term exterior bonding on rigid transport surfaces.
