Oil-Based Polishing Slurries
Saint-Gobain Surface Conditioning's oil-based polishing slurries feature cut-rate enhancing lubricants, dispersants, corrosion inhibitors, and suspension additives to maximize slurry life and performance. Safe and ready-to-use, our oil-based alumina slurries provide fast material removal and a controlled surface finish on a variety of metals.
MCA 852C Alumina Slurry
A high viscosity, oil-based alumina slurry with a smooth and creamy texture, Saint-Gobain MCA 852C contains special lubricants that lower the friction coefficient on the polishing surface to minimize drag and reduce subsurface damage. MCA 852C is designed for lapping and polishing stainless steel and metal components and may be diluted with water or oil to extend the life of the slurry.
Applications
- Polishing plastics and ceramics
- Lapping metals: stainless steel, aluminum, carbides, hardened steel and others
MCA 2225A Alumina Slurry
Developed specifically for polishing ball bearings, Saint-Gobain MCA 2225A is an oil-based alumina slurry that delivers maximum material removal while minimizing scratches and bringing luster to the polish. Made using highly refined powders for tight sizing and high purity, MCA 2225A can be used straight as an oil-based slurry or as a concentrate by diluting it with water-based coolants
Applications
- Lapping and polishing metals and stainless steel: ball bearings
- Excellent dispersion properties
- Provides fast material removal rate and controlled surface finish
- Ready-to-use slurries
- MCA 2225A is also available in dilutable concentrate form
- MCA 852C can be diluted 1:1 with water or oil depending on desired viscosity
- ISO certified for consistent quality
- Lapped parts can be cleaned easily with commercially available alkaline cleaners
- Knowledgeable application engineers available for technical support
