3M PSA adhesive backed Microfinishing Film is essentially a heavier duty version of imperial lapping film with a slightly thicker film backing and a harder compound of bonding resin.

Aluminium oxide particles are more pebble-like than silicon carbide particles so they don't fracture as easily and last longer.

A high-strength polyester film backing is coated with premium, micron-graded mineral particles that are electrostatically oriented for greater cutting efficiency. The particles are bonded into a layer of resin that wears away slowly for increased durability.

PSA is the acronym for Pressure Sensitive Adhesive and is a heavy duty version of the adhesive on the back of a Post-It note.

To use, cut each sheet into the desired width, peel the backing and fix a strip of each grade next to each other on a piece of float glass or other perfectly flat substrate applying firm pressure for an even secure bond.

Sheet size: 8½" x 11" (216mm x 279mm)

Grade: 60 micron

Mineral: Aluminium Oxide

    An integral part of the way we teach tool preparation and sharpening here at Waters and Acland furniture School. The scary sharp system stays flat. This abrasive is of the finest quality. It all works as it is supposed too. We flatten the backs of all plane blades and chisels with this system.
