r.rhenus TU 30 T

Application

r.rhenus TU 30 T is a water-miscible EP-coolant based on amine and boron acid for machining operations.

r.rhenus TU 30 T is an EP-coolant suitable for machining of aluminum alloys, for demanding operations on steel, cast iron and non ferrous metals.

r.rhenus TU 30 T emulsions feature a long time stability even under hot and humid weather conditions, contaminated mixing water and adverse machine surroundings.

Properties

semi-transparent, finely dispersed emulsion
very low foaming
excellent flushing effect
special long-term stability, good sump life
reliable long-time corrosion protection
good skin tolerance
pleasant smell
water hazardous class 1

Remarks

To prepare operating emulsion slowly add the coolant concentrate to drinking quality water assuring thorough mixing. Mixing can also be done by means of an automatic mixer.

Recommended mixing ratios:
Machining of steel and non ferrous metals: from 4 %
Machining of cast iron and high tensile steel: from 5 %
Machining of aluminium alloys: from 5 %

The concentration of the operating emulsion can be determined by means of a pocket efractometer. The °Brix value multiplied by the refractometer value equals the concentration n %. Sometimes reading of scale is more difficult with older emulsions because of the more coarse dispersivity.

Refractometer factor

1,3

Rhenus coolants are free of chlorinated organic substances, nitrite and secondary amines.This product contains natural raw materials. Therefore, different shades of colour and appearance are possible, however, quality and function of the product are not affected at all.
