Toughness, Cut-Rate, and Flexibility
The 3M™ Paper Disc 763U has the toughness, cut-rate, and flexibility required for aggressive paint prep and metal finishing applications. A mineral blend of aluminum oxide and 3M™ Ceramic Abrasive Grain — a tough, synthetic mineral — and a heavy F-weight paper backing combine to stand up to heavy-duty sanding without tearing, dulling, loading or edge wear.
Perfect for moderate to heavy stock removal as well as finishing, ceramic abrasives are engineered to handle intense heat and stress applications. When combined, ceramic/aluminum oxide blends surpass aluminum oxide alone in cut-rate and durability and make an excellent choice for difficult grinding applications.
Closed coat construction contributes to higher stock removal and longer life. It is great for final finishing and polishing on metal substrates, as well, because the dense concentration of mineral lays down a finer pattern.
Available in grades of 50, 60, 80, P100 and P120, 3M™ Paper Disc 763U is a premium product and is also available with 3M™ Stikit™ and 3M™ Hookit™ attachment systems.
Mixed Ceramic Abrasive
3M™ Ceramic Abrasive Grain is a ceramic mineral designed using a proprietary process to enhance toughness and hardness of the grain. For this increased performance, this paper feature aluminum oxide blended with 3M ceramic grain for a harder, longer-lasting abrasive. Perfect for light to moderate stock removal, ceramic abrasives are engineered to cut fast and handle intense heat and stress applications.
