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

Premium Al2O3 and SiC Lapping/Polishing 8" Discs

Premium, precision lapping 8" discs for producing a super-fine, super-consistent finish. A high strength smooth polyester film backing provides a uniform base for a coating of micrograded aluminum oxide or silicon carbide particles that are uniformly dispersed for greater finishing efficiency. A carefully controlled resin bond ensures a consistent, reliable and repeatable finish. Clean room coating and converting ensures contaminant-free products. 3mil (0.08mm) polyester film backing. Available with plain back or PSA (pressure sensitive adhesive) in 8" discs. The aluminum oxide discs can be used for polishing steps. Use wet or dry.
Applications: metals, plastics, metallography, thin film discs, floppy discs, fiber optic connectors.
NH = no hole.

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.

3M™ Adhesive Remover

Powerful replacement for mineral spirits, solvents and other unfriendly cleaners. Ideally suited for removing used grinding/lapping/polishing discs with PSA backing from their support discs. New food-grade citrus based 3M™ adhesive remover is also very effective in removing overspray of any aerosol adhesives, grease, oil, grime, tape residue, tar, wax, etc. A solvent-free formulation that provides wipe-away convenience with no filmy residue.

Active ingredient is listed as GRAS (Generally Regarded As Safe) for food contact applications under FDA21 CFR 182.20.
