Blackfast blackening chemicals provide simple and cost effective process for chemically blacking iron and steel at room temperature is now available, requiring no chemical knowledge and producing no environmental hazard.

Blackfast Chemicals' process is suitable for engineering works, workshops and toolrooms. By straightforward immersion in a series of tanks precision engineered components are rendered a deep black with no change to their overall dimensions. The benefits are lower cost, fast turn around of finished product, reduction in component stocks, flexibility and inhouse quality control.

The simple nature of the room temperature process means a Blackfast line is equally suitable for factory production employing a fully or semi automatic line or for a manual line in a small workshop or toolroom.

Unlike the conventional method of blacking, whereby components are immersed for 30 minutes in cauldrons containing chemicals boiling at 140 C, the room temperature process is essentially non-hazardous and is quick and easy to use.

The blacking solution does not carry a toxic or corrosive label. It is a safe, odourless solution used in water at a strength of 1 part solution to 3 parts water. Those companies that operate their own hot blacking line, or are considering changing their finishing process, can benefit in the following ways by adopting a room temperature blacking line.

There is no expensive capital equipment required - plastic or rubber lined tanks will do. Extraction equipment is either minimal or not necessary as there is no damage to the fabric of the facility - a common fault given the corrosive nature of the fumes from the hot blacking line. There are no heating costs, the solution can be used immediately and does not require 2 hours to reach operating temperature. There are no salts that subsequently leach out into holes and small orifices. A short dwell time allows rapid throughput of production and high coverage per gallon. The health benefit to the operator is immeasurable.

The Blackfast solution control is simple and replenishment is achieved by topping-up. Dumping is not necessary as with other systems. The Blackfast process is convenient and can be located anywhere without the need for ventilation or complicated control procedure. The solutions are stable, reliable and surprisingly easy to maintain.

A uniform black finish of steel components is, today, extremely popular and adds considerably to the perceived value of the product. This, combined with the unique quality that component dimensions are not altered and an even colour is achieved over blind holes and threads, makes it a must for any precision engineer.

Any precision engineering company manufacturing metal parts which require colouring and corrosion protection without resulting in dimensional change would benefit by installing their own Blackfast, room temperature blacking line.

Examples of product commonly blacked:

Machinery, Drills, Taps, Counter bores, Cast iron components, Hydraulic components, Jigs, Fixtures, Machine tools, Hand tools, Tool holders, Gauges, Gears, Moulds, Fasteners ........ and many more.
