Recirculating lapping additive for use on ceramics in the optic industry:
CHALLENGE 550HT was developed for use in “high-speed recirculating” and “high-speed once-through” slurry pumping systems. Utilizing the energy of a high speed circulating pump, standard on most lapping machines, it evenly disperses aluminum oxide, cerium oxide, silicon carbide, boron carbide, and garnet abrasive. It also reduces abrasive usage by eliminating “hard-packing” and waste.
