Description
We are offering 'Blackfasts', a room temperature blacking process that operates with a simple dip operation. Specifically designed for being used in factories, the dimensions are not effected materially by this process. Over the machined surfaces, threads and blind holes, a uniform coloring is obtained by this process. By the chemical conversion of the metal surface blacking is achieved. The process entails degreasing, immersion in a surface conditioner, and blacking solution. By a final immersion in dewatering oil, corrosion protection is achieved.


The products offered under this range are:

  • Iron & Steel Blacking Solution
  • Antique Brass, Copper, Pewter Solution
  • Antique Zinc Solution
  • Degreasing Solutions & Powders
