Challenge 543-HT

1 of 4 products in this brand
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.

Instructions

Handling

  • Challenge 543-HT should be mixed with deionized water and abrasive using the following slurry formula: 77 - 82 % water, 15 - 18 % abrasive, 3 - 5 % Challenge 543-HT. Use an agitator with a marine type propeller and a motor capable of 1750 RPM. Use a low shear dispense pump for feeding the mixed slurry onto the lap.
  • Disperse the abrasive with DI water at 1000 rpm for 3 minutes. Add 543HT. Mix for approximately 10 minutes depending upon abrasive surface chemistry. Be careful not to suck air into the slurry when mixing. A small vortex should form at the surface of the slurry. Turn the mixer off, or to a maximum of 50 rpm.

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.

Disposal

  • Dispose of in accordance with all applicable local regulations.
