Fine Results for Medium-Coarse Sanding
A grade range from P80 to P180 along with durable C-weight paper backing make our 3M™ Hookit™ Gold Disc 236U 150mm Sanding Disc ideal for auto body sanding projects including rough feather-edging, scratch refinement on bare metal, paint removal around damaged areas and more. With its open coat construction and aluminum oxide mineral abrasive, it provides a sharp cut — more aggressive than a comparable closed coat abrasive of the same grade — without dust accumulating on the disc. The Hookit™ Gold Disc 236U 150mm Sanding Disc is available in 3 or 6-inch diameter sizes for substrates including clear coat, fiberglass, filler, metal, paint, plastic and putty.
Resists Dust and Debris
Open coat construction means the abrasive grains on our 3M™ Hookit™ Gold Disc 236U 150mm Sanding Disc are placed with space between them to help evacuate sanding dust and other debris to avoid clogging the cutting edge of the grains. The load-resistant coating on the abrasive grains also allows the disc to continue cutting even when sanding paints, fillers, putties and other materials that would otherwise clog the disc and hinder sanding ability. All of this adds up to increased productivity and reduced material consumption.
The 6-hole pattern on select versions of 3M™ Hookit™ Gold Disc 236U facilitates dust evacuation, especially when used with a vacuum system. This design doesn’t even require alignment of holes with the disc pad, making disc changes quick and simple.

7-hole pattern on select versions facilitates dust evacuation
About Aluminum Oxide Abrasive
Aluminum oxide is popular 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 metalworking, including ferrous alloys, for auto body applications.
About Our Hookit™ Attachment System
3M offers a complete line of hook-and-loop style Hookit™ 150mm sanding disc for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. Hookit™ sanding discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.
Durable from Front to Back
Through a combination of science and strength — from the grain to the back-up disc pad attachment — our 3M™ Hookit™ Gold Disc 236U delivers long disc life, consistently sharp cut and superior dust resistance for better auto body operations.
3M™ Hookit™ Paper Disc 236U 150mm Sanding Disc offers aggressive cut and long life on a premium aluminum oxide disc with a durable edge and convenient Hookit™ attachment. A go-to product in many industrial operations, this durable disc is well suited for high production sanding operations as well as general purpose applications on paint, primer, wood, metal, plastic, and composites, including fiberglass.

Designed for use with a random orbital sander, the strong C-weight paper backing on our 3M™ Hookit™ Paper Disc 236U resists tearing and edgewear during aggressive sanding, and the disc is resin-bonded for heat- resistance, further increasing life and cut. These 150mm sanding discs also feature an open coat and a load-resistant coating to enhance dust management and cut-rate.
A load-resistant coating allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the surface of the disc and hinder sanding ability. Loading is further reduced by an open coat, which means the abrasive grains are spaced slightly apart so that dust can escape rather than obstructing the cutting edge of the grains, thereby optimizing cut-rate and disc life.

150mm sanding disc come in a variety of forms to fit various power tools and disc pads. We designed the 3M™ Hookit™ Paper Disc 236U to conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, to be removed cleanly and easily, and be simple to reuse. A load-resistant coating prevents wood dust, paint particles, and other debris from prematurely clogging the surface of the disc, optimizing cut-rate and disc life.
3M 150mm sanding disc 236U is made of aluminum oxide abrasive with excellent grinding power and durability. During rough processing, use temperature-resistant resin glue and stronger base material to give full play to the durability of this product. In finishing, using a soft and elastic base material can produce a smoother surface. The clogging coating on the surface can avoid abrasive clogging and maximize the performance of the product.
3M 236U sandpaper is used in the woodworking market for rough and fine sanding of the surface of plain boards, sanding of sapwood of plain boards, and sanding of special-shaped surfaces. It can be used with square vibrating machines and disc eccentric vibrating grinders.
Uses: Grinding in the car’s intermediate paint/primer workshop – removing foreign matter and surface particles, deburring sharp edges and surface adjustment of plastic products after molding.
