COMPEX is a blend of surface active agents, formulated
to serve two functions:
As an additive for vibrato finishing operations.
As a metal cleaner specialising in the removal of polishing compound
residues from polished metals by way of immersion. The cleaning
process may be assisted by ultrasonic energy.
mass finishing operations small metal articles are polished and
deburred by causing articles to rub against each other and selected
abrasive bodies in presence of COMPEX dissolved in water. The rubbing
action is performed in a doughnut shaped vibrating container. The
presence of COMPEX provides lubricated abrasion and therefore higher
brightness. A further benefit is its ability to prevent abraded
metal particles to adhere to the surface of its origin. Instead
COMPEX suspends metal particles and provides clean surfaces. The
optimum rate of addition is determined by experienced operators,
but is normally in the order of 0.1 to 1% of the water present.
use of COMPEX as a specialised cleaner for the removal of polishing
compound residues is described below. It is effective on most metals,
including steel, brass, copper, aluminium and also zinc base die-castings.
In addition to its use as a cleaner after polishing, COMPEX is also
extremely effective in removing oils and greases and is recommended
for the general degreasing of components in engineering works. A
further use for COMPEX is as an ultrasonic cleaner in the manufacture
of small precision components, such as watch parts and for the cleaning
of intricate jewellery.
CONCENTRATION: COMPEX is normally used at 30 ml / litre.
For ultrasonic cleaning only 20 ml / litre are recommended. Aluminium
components require a lower concentration of only 10 ml / litre.
70 - 99 degrees. For ultrasonic cleaning not hotter than 70 degrees.
MATERIAL: Mild steel tanks are suitable.
Mechanical or ultrasonic agitation assist with the cleaning.
TIME: 1 to 10 minutes.
After cleaning in COMPEX the articles are rinsed in clean water.
The metal surfaces will be water repellent after this rinse. If
electroplating is to follow, the water-repelling surface needs to
be converted to a water-accepting surface by the use of a second
cleaner with stronger alkalinity. We recommend Ferro GP2 as a soak
cleaner and Di-Lec if an electro cleaner is required.
Packaged in 25 litre drums.
COMPEX is of mild alkalinity and can be discharged into the sewer
without objection by most wastewater authorities. Skin contact may
cause irritation and dryness if exposure is over a long period of
time. For this reason we advise against more than casual skin contact.
Washing with water after exposure is always recommended. Eye contact
will cause irritation similar to soap solution. Wash the eye immediately
with large quantities of water.
