Lc 239 is a very strong descaler for destroying the most
Difficult scales. It effectively removes difficult scales, rust,
Oxides of metals, silica scale and hard soil from metal and
Other surfaces. It’s dissolving action is quick and thorough.
Most cost effective descaler when combined with lc 230,
Lc 233, lc 232 and lc 231. Do not use on materials like
Glazed tiles and glass. Must be used after dilution only.
Application
Dilute and blend with other descalers as necessary before dipping, brushing or
Spraying on surfaces. Clean surface free from excess rust, soil and dirt. Apply lc
239. Allow to stand for 10-20 minutes, then flush off with water. Surface may
Require repainting if necessary. Recommended to use lc 240 for neutralization
And lc 252 for passivating the native surface on ferrous metals. Avoid contact
With unwanted surfaces.
Dosage
For descaling purposes, dilute one part lc 239 with up to 20-100 parts of water
Depending on the type and thickness of scale and method of application. Allow to
Stand / circulate for several hours or as necessary. Flush with water until all the
Scale is removed. Repeat if scale is still present, check ph during application for
Control. Contact field chemist for further information. Do not use above 2% with
Non-chemical pumps for circulation
Handling & precaution
Strongly acidic. Irritating to eyes and skin. After contact with skin wash
Immediately with plenty of water. In case of eye contact irrigate thoroughly with
Water for at least 15 minutes. Seek medical advice. Avoid direct contact with
Glass, tiles and other such surfaces. Use adequate protective measures during
Use.
Packaging
Available in pail of 20 lt. Can also be custom packaged.
