Type III Melamine - Plasti-Grit® Plastic Blast Media is the hardest and most aggressive plastic media type. Melamine media blasting is ideal for mold cleaning; stripping paints, primers and coatings from steel and hard surfaces; and removing grit & grime from engines, turbines and parts. In mold cleaning, Melamine does not damage molds and is therefore an excellent replacement to glass beads and other hard abrasives. Type III meets the requirements of Mil-Spec MIL-P-85891A and is approved for use by the U.S. Army, Navy and Air Force.
