Technical specifications
FIPROPLUS 905 is a neutraliser and antioxidant. The use of this formulation is indicated to close phosphating cycles, acid pickling or degreasing of particularly delicate ferrous material. It is also indicated and recommended as an antioxidant additive in water-pneumatic test baths on items such as: radiators and radiant plates - sealing tanks petrol tanks, etc.

Bathroom control
The measurement of the pH value can be sufficient, which will be carried out with a special apparatus or indicator map; the values to be maintained depend on the mode of operation and should vary between 9 and 10.5.
.A more exact control of the bath can be carried out by chemical titration according to the following method:
by means of a calibrated pipette, exactly 10 ml of bath is taken, diluted with 20-30 ml of demineralised water and added with 4-5 drops of green bromocresol indicator solution. The liquid, which will take on a blue colour, is titrated with 0.1 N Hydrochloric Acid solution until it turns from blue to yellow.
The number of ml of acid used for toning will correspond to the bath score whose concentration can be traced by consulting the following:
CONCENTRATION [g/l] SCORE [ml hydrochloric acid 0.1 N]
5 1.75
10 3.50
15 5.25
To obtain the concentration of the passivant, multiply the number of ml of acid by the factor "2.86".
To reconcentrate the bath, approx. 2.86 g/lt must be added for each point found less than the set value. Alkalinity values can be varied by the salinity of the water.
Storage
Store the product away from direct sunlight and heat sources. The product fears frost: store at temperatures above 5 °C.
