Recommended Baumé: 25°, Note: for Micro Abrasive Aluminum Oxide Lapping Powders, larger number indicates smaller particles.
Microgrit WCA Precision Lapping Powders are highly recommended as a glass lens fining compound. The disc-shaped
particles lie flat so more surface contact is made than with conventional abrasives. This results in a faster and betterfined
surface. Microgrit WCA-T is suspension treated.
