The Stikit™ AdvantageOur 3M™ Stikit™ Paper Disc 426U is designed to handle a wide range of sanding and finishing needs. These high-quality, coated abrasive products come ready to use with a pressure sensitive adhesive coating on the backside so they conveniently press on to the backup pad and remove cleanly, leaving an uncontaminated surface for the next disc. The Stikit™ disc should be used in conjunction with our 3M™ Stikit™ backup pad (also called a disc pad and sold separately) that is attached to a disc sander, random orbital sander or stationary disc sander.Silicon Carbide AbrasiveThis paper disc uses silicon carbide mineral, which is a popular choice among industrial professionals because of its cut-rate and smooth finish. This synthetic mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut fast and produce a smooth finish. Silicon carbide products are commonly used for low-pressure applications such as sanding and finishing on wood, lacquer, paint and metal. While it wears faster than aluminum oxide, it produces a superior finish.Heat Resistant Resin BondingThis disc also uses a resin bonding which is specially designed to resist thermal deterioration, which can occur during sanding. This bond is very tough and excellent for precision work on hard and soft wood.
