Technical specifications
FIPROCOAT 9080 is a chrome-free pre-painting treatment product used to produce a conversion coating on iron, aluminum, and galvanized steel, which has excellent paint adhesion properties and provides effective protection against corrosion.
Use and Applications
FIPROCOAT 9080 is applied both by spray and immersion, in aqueous solution, according to these parameters:
Use concentration 10 - 40 g/l
Spray contact time 60” - 180”
Immersion contact time 120” - 300”
Operating temperature 20 – 40 °C
Operating conditions may vary depending on the result and the pretreatment system.
The Fiprokim technical service will provide, case by case, the optimal operating parameters.
It is recommended to perform a demineralized water rinse before treatment with FIPROCOAT 9080.
We also recommend maintaining the conductivity of this rinse below 60 µS/cm.

OPERATING PROCEDURE
Before carrying out the conversion, it is necessary to remove any contaminants from the surface of the parts to be treated, using alkaline degreasing baths, followed by several thorough rinses.
Prepare the bath using demineralized water and add from 10 to 40 Kg of FIPROCOAT 9080 for every 1000 liters of bath. Bring to working temperature and homogenize for at least 15 minutes before treating the parts.
Then add ALCAFIP 1051 until the pH of the working bath is stabilized at values between 4.3 and 4.8.
After treatment with FIPROCOAT 9080, it is necessary to rinse the parts with clean water, preferably demineralized (overflow recommended), followed by a final step with deionized or demineralized water.
The product can be used in combination with FIPROPLUS 915 which, alternatively, can also be used as a subsequent rinse to optimize paint adhesion.
Followed by drying at a temperature between 50 and 90°C.

Bath control
To check the point value of the working bath, proceed as follows:
Take 100 ml of the bath and transfer to a flask
Add 6 ÷ 7 drops of phenolphthalein indicator
Titrate with 0.1N sodium hydroxide (NaOH); the milliliters of 0.1 N NaOH consumed indicate the concentration of the working bath.
A bath prepared with 30 g/l of FIPROCOAT 9080 has a point value, without adjustment of pH, equal to 33 ml.
Adjusting the pH with ALCAFIP 1051 to a value of 4.65 gives a point value equal to 21,5 ml.
For greater accuracy in bath management, it is also recommended to periodically determine the zirconium points by complexometric titration of the test solution.
Power supply
The correct replenishment of the bath will be determined by the Fiprokim technical service, also based on the set overflow quantity. In any case, it is recommended to add 6 kg of FIPROCOAT 9080 for each missing zirconium point per 1000 liters of bath.
However, it is recommended to replenish continuously, using overflow to reduce pollutants, and to replenish based on the set pH.
Plant Requirements & Storage
All parts in contact with FIPROCOAT 9080 must be made of materials resistant to fluorides and acidity.
