Challenge 543-HT 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 543-HT reduces the amount of abrasive grain needed by up to 50%, while providing equal, and often greater, stock removal rates. It is particularly effective when using equipment with smaller slurry feed tubes, which constrict flow of high viscosity products. It is a single-pass lapping additive for use on ceramics in the Optic industry.

Vector HTN was developed for use in "high-speed recirculating" and "high-speed once-through" slurry pumping systems. Utilizing the energy of a high-speed 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. Vector HTN should not be used in "low shear" mixing/pumping systems. It is a lapping and polishing additive (recirculating).

Vector HTS products are biodegradable, viscous, polymer/surfactant mixtures formulated to be used with Aluminum oxide (either PWA type or FO Type) and de-ionized water to form a suspension type lapping slurry. Designed primarily for use in lapping silicon wafers, Vector HTS products fully disperse and suspend abrasive material for extended periods of time with relatively little change in physical or chemical characteristics. Designed for use on all types of lapping plates, the products perform particularly well with serrated or grooved plates. The HTS products differ chemically and physically, resulting in differences in wetting, film strength and viscosity. Some of the variables that effect HTS Product choice include: type of lapping plates, type of pumping system, brand of machine, operating pressure, type of abrasive. The choice of Vector HTS products provides the user with precisely the correct chemistry for achieving optimum results from a lapping process. It is a lapping and polishing additive for semiconductor materials.

Challenge 550-HT 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. It is a recirculating lapping additive for use on ceramics in the optic industry.
