ALC 40112 20 Grit Black Walnut Shells - 10 lbs.

50lbs; 40 grit; .025" approximate size; 6.0-7.0 MOHs; Coal Slag abrasive is a fast cutting, economical abrasive used to remove heavy rust scale or paint from steel and other hard materials; This abrasive is typically used in a pressure blaster or siphon blaster where the abrasive is not being recycled; Coal slag is moisture resistant and does not pack which reduces clogging; This abrasive has sharp angular edges and provides a high degree of etch for surface preparation and coating adhesion

25lbs, 20/30 grit; Melamine plastic grit is the most aggressive plastic abrasive when a fast strip rate of soft metals is desired; Melamine is used to clean, strip, de-burr soft metal substrates without generating heat that can warp the surface; Melamine can also be used to remove paint, oxidation and some surface rust; Melamine produces very little dust and improves visibility in a blast cabinet; Melamine is typically used in a blast cabinet or where the abrasive is being recycled

25lbs Medium, 20/30 grit, 0.032", 3.5 MOHS; Removes light surface rust or corrosion without etching the surface; Excellent choice for cleaning, stripping and de-burring soft metals without generating much surface heat; Typically used in a Blast Cabinet or where the abrasive is being recycled; Produces very little dust and improves visibility in a Blast Cabinet; NOTE: the size of the blaster nozzle should be three to four times larger than the grit size of the abrasive being used, the larger the nozzle size the more CFM of air is required
