Product Overview
Our 3M™ Green Corps™ Hookit™ abrasive sheet 255U combines features for smooth sanding on tough surfaces. Grade 36 to 100 ceramic and aluminum oxide blend abrasive is resin bonded to durable D or E weight paper backing, with open coat construction that reduces loading even on fresh filler. Sheets are ideal for shaping plastic filler and putty, paint removal and scratch refinement on bare metal.
3M Green Corps coated 751U sand paper sheet uses aluminum oxide as the abrasive material. 3M incorporates this aluminum oxide material into the sand paper sheet forming a grit of 40. The hook & loop attachment allows for easy mounting to the tool or pad. The sand paper sheet has a width of 2 3/4 in and length of 16 1/2 in. This abrasive is on a paper backing, E weight.

Specification parameters description:
Grit:
Grit is a measurement of the size of abrasive particles embedded in coated abrasives. The most common standards for grit size are the United States CAMI (Coated Abrasive Manufacturers Institute) and the European FEPA (Federation of European Producers of Abrasives). A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work. Grit is generally a unitless measure but is sometimes measured in microns.
Backing Weight:
Paper and cloth have a lettering scale for backing weight that measures strength of the material onto which the abrasive is mounted. Paper uses the letters A-F, where A is a lighter weight and most flexible and F represents a rigid, heavier backing. Lighter backings are typically paired with finer abrasive grits, suitable for blending and finishing. Coarser grits used for deburring and stock removal rely on a heavier backing. Cloth uses a lettering system of J, X, and Y for backing weight. J weight (jeans) is the lightest and most flexible, X weight (drills) is more durable and recommended for medium duty work, and Y weight is the toughest and least flexible. Fiber backings are made from chemically-impregnated paper to form a very hard, strong backing material. Fiber is used primarily for sanding discs. Polyester film backing provides high strength with a very thin backing and is used for very fine grits. It is more tear resistant than paper backing and is also waterproof.
Grade:
Grade is a measurement of the size of abrasive particles embedded in coated abrasives. It is a more general measurement of the level of precision, and corresponds roughly to grit. A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work.
