MCA-590 Lapping Vehicle and Lubricant

Product Code:  MCA-897A

CRE MCA-897A is an oil based slurry/vehicle that can be used straight as an oil based slurry or used as a concentrate by diluting it with water.

MCA-897A can be diluted up to 1:2 with water. For most applications, the recommended dilutation ratio is 1:1. When diluted 1:1 with water, the slurry can suspend up to 20µ particles. Depending on the dilution ratio and the required viscosity, this slurry can be made to suspend up to 60µ particles. This slurry is safe to work with and comply with EPA and OSHA safety requirements. It contains cut-rate enhancers to give aggressive cutting action during lapping and lubricants to help reduce scratching and subsurface damage in the work piece.

All slurries are made using highly refined powders that have tight sizing, high bulk purity, and high surface purity.
