Challenge 550-HT

Slurry Additive for Suspending Non-Treated Abrasives (Recirculating)

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. There are many benefits to using CHALLENGE 550-HT: No scratching, Less sub-surface damage, No hard-packing, less abrasive waste, increased removal rate, and easier post-lap cleaning. It is completely non-corrosive to equipment.

Handling Instructions

CHALLENGE 550-HT is used at approximately 5% (by volume) with deionized (DI) water or tap water. After CHALLENGE 550-HT is mixed with the water in the slurry tank, add the abrasive. The slurry will be ready for use almost immediately. Start grain loading 400 g/liter for a one-meter machine. Flow rate for the slurry should be approximately 300ml/minute for a one-meter machine.

Storage

Product should be stored in a temperature controlled environment. Prolonged exposure to temperatures at or below 32° Fahrenheit (0°C) is discouraged. Prolonged exposure to temperatures at or above 100° Fahrenheit (38°C) is also discouraged. In addition, material should always be sealed when not in use to prevent evaporation.
