Blackfast’s room temperature blacking process is safe, easy and convenient, the company states. The process has been developed for safe and reliable use in a metal working facility, so it is no longer necessary for parts to leave the production site for finishing by an outside contractor. Unlike conventional methods of blacking, it is non-hazardous and easy to use.
Blacking of iron and steel provides a corrosion resistant finish without dimensional change. This is attractive for machined parts manufactured to tight tolerances, where plating or painting would not be acceptable.
As it is very important that the components are clean and free from grease before using the blacking process. Blackfast also offers a range of degreasers from solvents to water based and rust removers.
