3M™ 8172 is an optically clear laminating transfer adhesive, for bonding smooth, transparent substrates. It offers high temperature, humidity, and UV resistance as well as long term durability without yellowing, delaminating, or degrading. 8172 has a light transmission >99% when corrected for reflection losses.
It is coated and converted in a clean room and wound on plastic cores and wrapped in plastic to eliminate paper fiber contamination. This optically clear adhesive is used for bonding film and glass laminates in touchscreens, optical management of LCDs and transparent graphic overlay applications.
8172 optically clear tape is available in non-standard slit rolls, sheets and custom shapes.
