  • Provides uniform grinding, even at high temperatures

3M™ Boron Carbide Abrasive Pastes are general-purpose abrasives and lapping agents. 3M™ Boron Carbide is an extremely hard material (9.5+ Mohs), making these pastes suitable for lapping and fine grinding of a wide range of materials.

A Preferred Choice for Mechanical Engineering
Applications for 3M™ Boron Carbide Abrasive Pastes include the machining of drawing dies, molds and dies of all kinds, wire guides, valves, valve seats, cylinder bushes, cylinder faces, injection pumps, hardened bearing surfaces, gauges, cutting and blanking tools, reamers and mill cutters.

3M boron carbide abrasive pastes are used in the manufacturing of industrial equipment for cost-effective lapping and fine grinding of thermoplastics, nonferrous metals, steels, titanium, hard metals, optical glass, natural and synthetic gemstones and ceramics. Even with very rough surfaces, a metal sealing surface (less than 1.4 μm) can be achieved in two operations by coarse pre-grinding with a grain of F220 and final grinding with a grain of F400.

A Range of Grain Sizes to Meet Specialized Applications
3M boron carbide abrasive pastes are available with a variety of grain sizes according to FEPA standards, with additional sizes available upon request. These grain sizes cover a range of applications, from coarse material removal to extremely fine precision machining.

How to Use 3M Boron Carbide Abrasive Pastes
3M boron carbide abrasive pastes can be used at application temperatures up to 200°C. The polyalcohols used in these water-soluble pastes are almost completely biodegradable (>90%), and are therefore rated 0 according to German water hazard classification.

Suitable diluents include water (preferably demineralized) and polyethylene glycol 400 (PEG 40). When adding water, only add one drop at a time, since larger amounts of water can dissolve and extract the polyalcohols in the paste base. At service temperatures from 100°C to a maximum of 200°C, PEG 400 (which is also a component of the paste base) should be used as a diluent.
