3M™ Boron Carbide Lapping Pastes, watersoluble (previously TETRABOR®)


For universal application (titanium, hardest stainless steel, ceramics, plastics)

The suitability of boron carbide for this purpose is the result of its extreme hardness of 30,000 N/mm².

Use and application

In all ranges of engineering where economic and cost-effective lapping and superfinishing is required, for example for non-ferrous metal, titanium, hard metal, steel, ceramics, minerals, plastics (teflon).

Treatment of drawing dies, bottom dies of all types, tools and wire guides, valves, valve seats, cylinder liners, cylinder running surfaces, injection pumps, hardened seats, setting jigs, cutting- and blanking tools, broaches, cutters, optical lenses, natural or synthetic gemstones as well as all ceramics.

Working advice

Watersoluble pastes can be used for an application range up to max. 200°C.

The supporting materials used in our watersoluble pastes are almost entirely biodegradable (>90 %) and are therefore classified as not hazardous to waters.

Cleaning of the processed parts can be conducted with water. Please pay attention to anti-corrosive protection.
