150MM Disc Abrasive Mesh Paper

PAPER AND CLOTH ABRASIVE SHEETS
9 x 11" Abrasive Sheets

Paper:

The backings used for Marvel sheets are uniform, precision technical papers made to very exact specifications. The nature of the application and the flexibility required determine what weight paper to use. Standard weights used in Marvel paper sheets are 40, 70 and 100 pounds and are indicated by a letter code imprinted after the grit size on the backing of all abrasive sheets.

Paper Applications:

Finishing Paper: Aluminum oxide grain. Light weight and very flexible backing (a). Primarily used for hand finishing and orbital or vibratory sanding. Open coated grain surface resists loading.

Cabinet Paper: Aluminum oxide grain. Medium-light (C) and medium-heavy (D) paper backings blend reduced flexibility with added strength. Cabinet paper is most frequently used to remove surface defects left by machine sanding before finishing. Open coated grain surface resist loading.

Waterproof Paper: Silicon carbide grain. Latex treated light (a) to medium-light (C) paper backing used with water in hand and mechanical sanding applications. The water functions both to cool and lubricate the work piece while carrying away swarf build-up. Most often used between coats of painted, varnished or lacquered surfaces for very fine finishes. Closed coated grain surface.

Zinc Stearate Paper: Silicon carbide grain. This finishing paper was developed for fine sanding of sealers and primers. The zinc stearate provides greater resistance to loading than standard finishing papers with zinc stearate acting as a lubricant. Available in an open coated grain and A-weight paper backing.

Cloth:

Marvel cloth sheets are manufactured from high quality woven cotton fabric that is pre-shrunk, stretched and filled to produce the durability, flexibility and surface constancy needed in sanding applications. As with the paper sheets, all cloth sheets indicate the cloth weight (X or J) and the grit size on the sheet backside.

Cloth Applications:

Metal Cloth: Aluminum oxide grain. These durable, general purpose metal cloth sheets are extremely popular because they can be used in so many industrial applications, ranging from rough to fine sanding on all types of materials. Closed coated grain surface in X and J (depending on grit size) cloth backings.

Emery Cloth: Composite of corundum and iron oxide grain bonded to a J-weight cloth backing. The blocky characteristic of this grain tends to cut slowly, polishing more than abrading. Most commonly use for general maintenance work. Closed coated grain surface.
