The Benefits of Silicon Carbide
Creating a durable, long-lasting abrasive begins with the mineral. We chose silicon carbide for our 3M Wetordry Paper Roll 734 ? a very hard mineral that fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide sandpaper products are commonly used for low-pressure applications such as paint prep and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a superior finish. This product also offers a lightweight paper backing that delivers good flexibility, so users don?t have to worry about gouging or denting the workpiece. Closed coat construction means silicon carbide mineral covers 100% of the paper backing. Given the dense concentration of mineral, these paper rolls leave a fine scratch pattern.
The Wetordry Advantage
Our 3M Wetordry products are backed with our waterproof paper backing that supports both wet and dry applications. Lighter weight and smoother than cloth, paper backing is preferable for lighter applications such as finishing and paint prep. At the same time, many such applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects can be minimized by sanding with water or coolant to rinse dust away from the workpiece and the abrasive surface. In short ? 3M Wetordry Paper Roll 734 is like having wet and dry sandpaper in a single product.
These versatile paper rolls are ideal on e-coat primer and wood and may also be used wet or dry for finishing metal and gel coats. In the marine industry, they are used for sanding old finishes, fine feather edging and surface work.
