benefits of changing from hot blacking

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:

cog

There is no expensive capital equipment required – plastic or rubber lined tanks will work.
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.
