Single-pass lapping additive for use on ceramics in the optic industry:
CHALLENGE 543HT is a medium viscosity lapping/polishing slurry additive which evenly disperses and suspends a variety of non-suspension-treated abrasives, including aluminum oxide, zirconium oxide, along with silicon carbide, boron carbide, synthetic and natural diamond, and garnet. Because of its superior suspension characteristics, CHALLENGE 543HT reduces the amount of abrasive grain needed by up to 50 %, while providing equal, and often greater, stock removal rates. 543HT is particularly effective when using equipment with smaller slurry feed tubes, which constrict flow of high viscosity products.
