waterproof abrasive paper

waterproof abrasive paper Silicon carbide waterproof abrasive paper Material Materials used for the abrading particles are : no longer commonly used : commonly used in : commonly used to abrade or polish metal : perhaps most common in widest variety of grits; can be used on metal (i.e. body shops) or wood : available in very coarse grits all the way through to microgrits, common in wet applications alumina-zirconia: (an aluminium oxide alloy), used for machine grinding applications : used in extremely fine micron grit ( level) papers : used in high pressure applications, used in both coated abrasives, as well as in bonded abrasives. It is used to remove small amounts of material from , either to make them smoother ( and ), to remove a layer of material (e.g. old paint), or sometimes to make the surface rougher (e.g. as a preparation to ).
