Technical specifications
FIPROPHOS 1152 is a liquid phosphate degreaser for the treatment, in spray systems, of ferrous, galvanized, and aluminum workpieces. Formulated with a special detergent package, it provides good results even at room temperature, without foaming. It forms an iron phosphate deposit on the treated ferrous metal, which improves paint adhesion and, at the same time, increases resistance to under-film corrosion.
In the event that workpieces heavily contaminated with oils or greases need to be treated, the Fiprokim Technical Service will provide recommendations for the use of a suitable degreasing additive.
After treatment with FIPROPHOS 1152, the material must first be spray-rinsed under pressure (1 - 2 bar) with continuous renewal, for 1 - 3 minutes at room temperature, and subsequently with demineralized water.
To further improve the final result, suitable passivating products for ferrous materials can be used.
Use and Applications
FIPROPHOS 1152 must be used in an aqueous spray solution under the following operating conditions:
Treatment time: 1 ¸ 4 minutes
Operating temperature: ambient ¸ 50°C
Concentration: 10 ¸ 30 g/l
Bath points: 3.2 ¸ 9.6 points of total acidity

PREPARATION OF SOLUTIONS
For every 1000 liters of solution, use from 10 to 30 kg of FIPROPHOS 1152.
Fill the tank with water and bring it to the working temperature; then, add the pre-set quantity of FIPROPHOS 1152 with the pumps running and circulate the solution for at least 10 minutes before the entry of the first material to be treated.

Bath control
Take 10 ml of sample
Add 4-5 drops of phenolphthalein indicator and titrate with a 0.1 N sodium hydroxide solution.
The number of ml of 0.1 N sodium hydroxide used represents the bath points.
For a bath prepared at 20 g/l, it should be approximately 6.3.
Power supply
For each missing point of acidity, add 3.2 kg of FIPROPHOS 1152 per 1000 l of bath.
