(For Degreasing & Derusting at Low Temperature)
SCALGUN-B is an aqueous inhibited acidic mixture, soluble in varying proportions with water. It is a very effective degreaser cum deruster for iron & steel surfaces at low temperature. It has very good penetrating power to disintegrate and dissolve, machine oils, light greases, lubricants as well as rust or scales; either be dipping process or by swabbing.
Although SCALGUN-B is an excellent remover of light grease and oil, usually heavy soil contamination should be removed first either in kerosene or by manually wiping off with a cloth soaked in SCALGUN-B solution. Similarly surfaces having extremely heavy rust formation should be removed mechanically or by means of wire brush during dipping method.
The following parameters should be followed depending on soil contamination, cycle time, etc. Actual parameters should be set after conducting initial trials.
10% - 25% (v/v)
R.T. - 45°C
v/v = volume by volume; R.T. = Room Temperature
Please note that time temperature and concentration are interdependent on each other, thus set the parameters accordingly.
Plastic or FRP lined M.S. tanks/containers should be used. Where heating of the bath is required then ptfe coated electric immersion heater should be used or external heating can be employed, but care should be taken that temperature does not exceed 45°C.
Concentration:- For heavy contamination : 1:1 or 1:2 with water
For medium contamination : 1:3 or 1:4 with water
For light contamination : 1:5 or 1:6 with water
