TECHNICAL DATA
Hastilite 250
BC1250
BC1250, BC12505, BC1250P

Hastilite 250 has a unique composition of small alpha alumina crystals with a mixture of rare earth minerals resulting in a polishing slurry that will reduce manufacturing cost and provide efficiently polished surfaces. Hastilite 250 is intended for pad polishing of a broad range optics and glass.

Application

Dilute Hastilite 250 with water to create slurry. Preferred, but not required, water type is DI or RO water. Concentration can vary per operation. For best results, please consult with UPI technical staff to recommend optimal processing conditions.

Hastilite 250 is suitable for recirculatory central slurry systems for improved efficiency and reduction in costs.

Benefits
  • Unique polycrystalline alpha alumina crystals produce polish rates in excess of two times that of conventional products in many applications.
  • Engineered rare earth additives provide the finishing required for precision optics.
  • High resistance to particle breakdown correlating to longer slurry life.
  • Polishing uniformity across the entire glass surface.
