Diamond Lapping Film Discs
Diamond lapping film discs are micron graded diamond particles resin bonded to a uniform 3-mil polyester film backing. This offers a cleaner, more consistent alternative to diamond compounds or slurries. They are used to finish and polish hard-to-grind materials such as glass, ceramics, hardened metals, composites and micro-electronic materials for SEM and TEM analysis. Used wet or dry.
PSA means "Pressure Sensitive Adhesive" backing is on the disc. "Plain back" has no adhesive backing.
