waterproof silicon carbide sanding paper backing to provide superior finishing for wet applications on a variety of substrates, especially copper PCB board.size is 210 x 270 mm, No.280

 Features:

1. This versatile sheet can be used wet or dry on paint, primer, gel coat, metal, and wood finishes

Used dry or with water, C34P Paper Sheets enable the user to rinse areas of the workpiece and the sheet during use to prevent dust and debris from clogging the points of the abrasive and reduce air-borne dust while producing a faster cut at the same time. These versatile sheets are ideal on surfaces that tend to generate a lot of dust, such as paint and primer; and can also be used dry for finishing metal and gel coats. In the marine industry, they are used for sanding old finishes, fine feather edging, and surface work.
 
2. Strong C-weight paper backing provides durability for either hand or machine sanding Silicon carbide is a very hard mineral characterized by sharp points that fracture easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as paint prep and finishing on wood and metal. While the mineral has a shorter life than aluminum oxide, it produces a superior finish.
