Durabis

Durabis (Latin for "you will last") is a brand name for a clear polymer coating developed by the TDK Corporation. The need for a protective polymer arose because the data layer on Blu-ray Discs is much closer to the surface of the disc than in other disc formats, such as HD DVD. One of its principal applications at first was for scratch resistance in Blu-ray Disc and other optical discs. It is claimed to be tough enough to resist screwdriver damage and make scratched optical discs (CDs and DVDs) a thing of the past.
