benefits

In-house use – A simple dip process that can be used for single items or batch work. No preparation, simply remove the tank lids and the line is ready for use
Low temperature – Reduced energy costs and quick start up. No hazardous Fumes.
Concentrated liquid – Low chemical usage, cost effective and efficient

Blackfasts' room temperature blacking process is a simple dip operation specifically designed for use in factories. A uniform colouring is obtained over machined surfaces, threads and blind holes. Blacking is achieved by chemical conversion of the metal surface.
