3M™ DF100L Uniformity Tape Technical Data Sheet Release B, October 2013 Material Substrate PolyesterFilm Prism Layer Acrylic Resin Adhesive Acrylic PSA Structure Prism-shaped acrylic resin optical features formed on polyester film substrate. 24 μm Pitch Product Description 15 μm 3M™ Uniformity Tape ("UT" or “Product”) is a clear, microstructured thinfilm that mixes and diffuses light generated by LEDs in edge-lit lighting. UT is applied directly to the injection edge of a Light Guide Plate (LGP), which faces the LED light sources. The Product has adhesive on one side, a micro-replicated optical pattern on the other. UT’s microstructure reduces dark zones and improves brightness uniformity by inducing lateral light spreading in the plane of the light guide near the light source. Recommended End Uses LED solid light guides and wave guides for architectural and commercial lighting. Key Attributes • Improves brightness uniformity and light spreading near light source • Reduces head-lighting effect Polyester 50 μm Adhesive 50 μm 115 μm ±5 (without liner) Cross section image not to scale.

The prisms are easily damaged. Recommended Storage and Handling UT should be stored flat, in its original packaging, away from direct sunlight. If UT is dedicated to LEDs, there should be no UV damage. UT is stored at a temperature of 20 ±10 °C, relative humidity 45 ±15%. The recommended temperature range during application is 20 ±10°C, relative humidity 45 ±15%.
