3M™ Imperial™ Diamond Lapping Film Type 661X, 8" Discs

Imperial™ Diamond Lapping Film offers a repeatable, precision finish on extremely hard materials. It combines micron-graded diamond particles, a resin bonding system and a highly uniform 3mil (0.08mm) polyester film backing for a cleaner, more consistent alternative to diamond compounds or slurries. Better than paper backing under wet conditions. Available with Plain back or PSA (pressure sensitive adhesive) in 8 " discs. NH = no hole. Type 661 Imperial™ Diamond Lapping Film replaces type 651. Type 661 has a more robust, 3 mil (0.08mm) polyester backing film, while the type 651 had a 2 mil (0.05mm) backing film.

Applications: carbides, ceramics, high-hardness metals, fiber optic connectors, magnetic heads

3M™ Trizact™ Film, Aluminum Oxide, 8" Discs

get your job done faster with a superior finish using 3M™ Trizact™ Film

Ideal for damp finishing solid surfaces, glass defect repair and acrylic solid surface finishing. 3M™ Trizact™ consists of aluminum oxide particles having tiny precisely shaped pyramids reproduced on a polyester film backing. Also useful for: metals, plastics, composites, ceramography, metallography. The pyramids wear away evenly and continually expose new abrasives. Fewer processing steps can be taken, a higher gloss level achieved and effective surface leveling takes place. Little wear is required and there is easy “touchup”. Waterproof backing. Available in 8" discs with PSA (pressure sensitive adhesive) back.
