Oil-Based Lapping Slurries
Saint-Gobain Surface Conditioning offers a line of oil-based lapping slurries designed for surface finishing of stainless steel, metal and ceramic components. Our ready-to-use slurries contain cut-rate enhancing lubricants, dispersants, corrosion inhibitors and suspension additives to extend the life and performance of the slurry.
Safe to work with and environmentally friendly, Saint-Gobain’s oil-based slurries comply with EPA and OSHA requirements.
MCA 852D Alumina Slurry
Saint-Gobain MCA 852D is a high viscosity, oil-based alumina slurry that has been optimized for lapping and polishing a wide range of metals, plastics and some ceramics (alumina and zirconia). Its smooth, creamy texture allows the slurry to adhere to parts and remain on the plate longer during lapping and polishing, for the most efficient and consistent cutting.
Applications
- Lapping and polishing plastics and ceramics
- Lapping metals: stainless steel, aluminum, carbides, hardened steel and others
MCA 2242 Alumina Slurry
A relatively low viscosity oil-based suspension slurry designed for general industrial lapping, Saint-Gobain MCA 2242 alumina slurry provides fast cutting on ceramics and metal parts used in automotive and steel applications. MCA 2242 contains suspension additives to prevent hard packing of the abrasive during use, helping to keep more abrasive particles in the slurry participate in cutting during lapping.
Applications
- Lapping seal rings, carbides and hardened steel
- Excellent dispersion properties
- Provides fast material removal rate and controlled surface finish
- Ready-to-use slurry
- ISO certified for consistent quality
- Lapped parts can be cleaned easily with commercially available alkaline cleaners
- MCA 852D can be diluted 1:1 with water or oil (depending on desired final viscosity)
- Knowledgeable application engineers available for technical support
