Product Details
3M™ Wetordry™ Paper Sheet 431Q features extra-fast cutting silicon carbide on a strong C-weight, waterproof paper backing designed for superior finishing in both wet and dry applications across various substrates, including paint, primer, gel coat, metal, and wood. These sheets can be used dry or with water, allowing users to rinse areas of the workpiece and the sheet during use to prevent dust and debris from clogging the abrasive points and reducing airborne dust, while achieving a faster cut. The versatile 9 inch x 11 inch sheets are suitable for surfaces that generate significant dust and can be cut to size as needed for specific applications. Silicon carbide, known for its sharp points that fracture easily, results in freshly exposed sharp edges that provide a smooth, professional-looking finish. Although silicon carbide typically has a shorter lifespan than aluminum oxide, it offers superior finishing capabilities, making it ideal for low-pressure applications such as paint preparation and finishing on wood and metal. The proprietary waterproof paper backing supports both wet and dry use, while being lighter weight and smoother than cloth, making it more suitable for lighter applications like finishing and paint prep. Common applications for these sheets include blending, cleaning, coating removal, deburring, finishing, and paint stripping, and they are frequently utilized in industries related to coatings.
