DUPONT STAUROLITE
DuPont produces their coarse Staurolite sand product from their heavy heavy mineral deposits in Starke, Florida. This naturally occurring rounded mineral sand is chemically scrubbed, washed, and graded to give a product free from dust, dirt, and ultrafines. The staurolite sand is then magnetically separated from other heavy minerals to produce a highly uniform grade.
Applications Coarse Staurolite should only be selected when a heavy paint film is to be removed or a deeper profile is needed that cannot be obtained with our recommended Starblast or Starblast Ultra blasting abrasives. Similar to other DuPont abrasives, Corase Staurolite offers the same product advantages, such as:
- greater blasting visibility due to considerably less dust generation
- lower labor costs through faster, more efficient cleaning
- less material costs due to reusability
- guaranteed to contain <5% free silica, typically>3%
- rounded to subangular grains result in less abrasive embedment
- electircally nonconductive
