Most Popular Abrasives
|
When using a Skat Blast Cabinet, a variety of dry abrasives can be used depending on the requirements of the user.
Generally, the higher the grit number, the finer the abrasive. The finer the abrasive, the smoother the finish. Coarse-grit
abrasives cut fast, but the finish isn't quite as smooth as with fine-grit abrasives.
|
Most popular abrasives are Glass Beads, 1st Choice, and Speed Bead for a very fine finish on parts; Skat Magic™ for a medium
finish and faster production. In addition, ground Walnut Shells can be used for special applications. Aluminum Oxide is another popular abrasive for fast cut and long life.

 "When abrasive blasting aluminum, brass or softer metals, use a lower air pressure (40-60 psi) for best results. The same applies to carving or etching glass. Hard metals such as fenders, bumpers, etc., can be cleaned best using 50-80 psi. We recommend the cabinet hookup kit for regulating air pressure and collecting moisture effectively."

* Cleaning Time based on removing the paint finish from a mid 1980's factory fender down to bare metal. Using a Skat Blast Abrasive Blast Cabinet with
15-20 cfm @ 80 psi and a medium nozzle and air jet installed in the gun. The fender consisted of a sealer coat, primer coat, and baked factory paint coat.
