MCA-590 Lapping Vehicle and Lubricant

Product Codes:  MCA-590, 590A, 590B

CRE MCA-590 is one of our engineered vehicles that are ready to use with cut-rate enhancing lubricants, dispersants, corrosion inhibitors, and suspension additives to extend the life and performance of the slurry.  

MCA-590 keeps the plates running cool by minimizing sludge build-ups and allowing the plates to dissipate heat during operation.  MCA-590 is designed to be compatible with most abrasive materials such as SiC, B4C , Al2O3, zirconia and others.  This vehicle can be used safely to lap and polish a wide range of metals, ceramics and crystals.  This slurry is safe to work with and completely biodegradable. 


MCA-590B offers slightly better suspension properties than MCA-590A.
