  1. What is the 3M™ Hookit™ Paper Sheet 236U used for?

    The 3M™ Hookit™ Paper Sheet 236U is commonly used for sanding and removing imperfections on various surfaces such as wood, paint, metal, and fiberglass.

  2. What does P150 C-weight mean?

    P150 indicates the abrasive grain's roughness level while the C-weight signifies its thickness. Together they determine how effectively it can remove materials during sanding.

  3. How many sheets do you get per case of the product?

    There are ten packs in a single case of the 3M™ Hookit™ Paper Sheet. Each pack includes fifty pieces of 3-inches by four-inches paper sheet.

  4. Is this paper sheet compatible with random orbital sander machines that have hook-and-loop backing pads?

    Yes, it is compatible with most machines that have a hook-and-loop backing pad system because of its special coating that allows easy removal from and reattachment to circular-holed discs.

Product Description: 3M™ Hookit™ Paper Sheet 236U

The 3M™ Hookit™ Paper Sheet 236U is designed to be used with a 3 x 4 inch orbital sander. The sheet has a strong C-weight paper backing that resists tearing and edgewear during aggressive sanding. Additionally, the sheet is resin-bonded for heat-resistance, which increases its life and cut.

The sheet features an open coat and a load-resistant coating that enhances dust management and cut-rate. The load-resistant coating allows the sheet to continue cutting even when sanding softwoods, paints, and other materials that would otherwise clog the surface of the sheet and hinder sanding ability. The open coat means that the abrasive grains are spaced slightly apart, reducing loading and optimizing cut-rate and sheet life.

The 3M™ Hookit™ Sheet conveniently and firmly attaches to a 3 x 4 inch (75 x 100mm) 3M™ Hookit™ Pad (sold separately) on a 3 x 4 inch 3M™ Orbital Sander. The Hookit™ sheets are quick and easy to change when switching from one grade to another and can be reused again and again for the extent of the sheet life. Adhesive-backed sheets are typically discarded after one use because the adhesive backing will not re-adhere a second time.

Aluminum oxide is the mineral used in the 3M™ Hookit™ Paper Sheet 236U. It is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
