3M Imperial Lapping Film
3M ®Imperial® Lapping Film is our premium, precision abrasive for producing a super-fine,
super-consistent finish. A high strength polyester backing provides a uniform base for a
coating of micron graded mineral 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.

3M Imperial® Microfinishing Film®
A fast cutting abrasive that provides precise, consistently uniform, close-tolerance
finishes. A high-strength polyester film backing is coated with premium, micron-graded
mineral particles that are electrostatically oriented for greater cutting efficiency,
and resin-bonded for increased durability.
Applications: metal, plastic, fiberglass, solid-surface composites, wood, paints
and primers, automotive power train components, superfinishing.
Converted Forms: sheets, discs, rolls, belts.
Available Backings: 3 mil or 5 mil thickness. Discs and sheets available with
self-adhesive, Stikit® , or Hookit® backings.
Available Minerals: Aluminum Oxide and Silicon Carbide.
Available Grades: 180, 150, 120, 100, 80, 60, 50, 40, 30, 20, 15, and 9. (Not
all grades available in all products.)
Imperial® Microfinishing Film Type S: has our standard backsize for non-slip
performance. Designed primarily for roll goods to be used in indexing operations.
Imperial® Microfinishing Film Type Q: has a more aggressive backsize than the
standard product. Designed primarily for roll goods in indexing operations such as
crankshaft and camshaft polishing where additional friction is required for non-slip
Imperial® Fre-Cut® Microfinishing Open Coat Film: Mineral is applied to the
backing in a open coat pattern to prevent loading and increase product life. It's
Fre-Cut® coating provides extra loading prevention in dry sanding operations. Developed
for use on softer materials such as wood, polyurethane, paints, sealers and plastics.
Our experienced staff can assist you in setting up your polishing procedures to ensure
that you are getting the most from your 3M films.
- United States Supply Co., Inc. inventories most grades of microfinishing films for metal finishing.
- With major concentration on polishing chrome plated rolls, we inventory grades from 60 micron to 9 micron in roll sizes of 4" and 8" ready to mount on most any polisher made.
3M Coated Abrasives
Today, coated abrasives have become an indispensable tool for processing a multitude of
materials. Applications range from surface leveling and smoothing, to polishing and
grinding. Based on nearly 100 years of experience, 3M Research has been a leader in
developing many new coated abrasive products and systems for modern production operations.
Coated abrasives are manufactured from three materials: a mineral, a backing and an
adhesive bond. 3M uses 7 minerals, 5 backings, and 4 bonds to offer a vast number of
practical, durable production tools. United States Supply Co., Inc can assist you in
finding the right combination for maximun value and performance.
Minerals: emery, garnet, aluminum oxide, alumina zirconia, silicon carbide, ceramic
aluminum oxide, and industrial diamonds.
Backings: paper, cloth, fibre, combination, and polyester film.
Bonds: glue, resin over glue, resin over resin, waterproof.
Coatings: open coat, closed coat, gravity process.
Lead Time: As an authorized agent for 3M abrasives, United States Supply Co.,
Inc., stocks common sizes and others are available within 1 day on standard 3M items.
3M Scotch-Brite® Hand Pads
3M Scotch-Brite® Hand Pads out perform steel wool and wire brushes. They are fast
cutting with consistent finish for surfaces that need to be cleaned or finished by hand.
These pads are non-rusting and can be used with water or solvents. We recommend the 7447
hand pad as the best starting point for cleaning and finishing. There is no question that
3M Scotch-Brite® is your best choice for cleaning and finishing surfaces by hand.
3M Imperial® Diamond Lapping Film
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 polyester film.
Applications: carbides, ceramics, high-hardness metals, rocks and minerals, fiber
optic connectors, magnetic heads, roll finishing for paper mills, metallurgical testing, and other lapping and polishing
Converted forms: sheets, discs, rolls.
Available Backings: 0.5, 1, 1.5, 2, and 3 mil backings. Sheets and discs available
with self-adhesive backing.
Available Grades: 0.1, .05, 1, 1.5, 3, 6, 9, 15, 20, 30, 45, and 60 micron. (Not
all grades are available in all products.)
Imperial® Diamond Lapping Film Type B: Diamond particles are contained in ceramic
beads which makes this product more aggressive than the standard product. Grade for grade
a Type B product will yield more cut, longer life, and a coarser finish. Recommended for
extremely hard materials and larger parts.
Imperial® Diamond Lapping Film Type P: The resin bond is harder that the standard
product. Used primarily in roll superfinishing applications and flat lapping operations.
Imperial® Diamond Lapping Film Type H: Provides a higher cut rate and longer life
than the standard IDLF. A thicker diamond coating and harder resin prevent "score
through" and increase cut rate, making this a long lasting, clean polishing, premium
diamond abrasive. Used primarily for fiber optics and Connector polishing.
