3M™ Hookit™ Paper Sheet, 236U, P240, 3 2/3 in x 9 in (93.1 mm x 228.6 mm)

The 3M™ Hookit™ Paper Sheet 236U is a premium aluminum oxide sheet with a durable edge and convenient 3M™ Hookit™ Attachment. A go-to product in many industrial operations, this durable sheet is well suited for high-production sanding operations as well as general purpose applications on paint, primer, wood, metal, plastic, and composites, including fibreglass.Designed for use with a 3 in x 4 in (7.62 cm x 10.16 cm) orbital sander, this sheet's strong, C-weight paper backing resists tearing and edgewear during aggressive sanding. The sheet is resin-bonded for heat-resistance, further increasing life and cut. The 3M Hookit Paper Sheet 236U also features an open coat and a load-resistant coating to help enhance dust management and cut-rate. A 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. 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 sheet life.
