Technical specifications
FIPROCOAT 9001 is a chromium- and heavy metal-free pre-painting treatment product used to produce a blue colour conversion on iron, and a colourless to iridescent conversion on aluminium and galvanised. The resulting coating layer has excellent anchoring properties for the paint and provides valuable protection against corrosion. For use in lines subject to flash rust.
.Usage and Applications
FIPROCOAT 9001 is applied either by spraying or dipping, in an aqueous solution, according to these parameters:
Use concentration 10 - 50 g/l
Contact time spray 60" - 180"
Submerge contact time 120" - 300"
Operating temperature 20 - 50 °C
The operating conditions may vary depending on the result and the pre-treatment plant.
The Fiprokim technical service will provide the optimal operating parameters on a case by case basis.
We recommend a rinse in demineralised water before treatment with FIPROCOAT 9001.
We also recommend keeping the conductivity of such a rinse below 60 µS/cm.

OPERATIONAL PROCEDURE
Before carrying out the conversion, it is necessary to remove any pollutants from the surface of the parts to be treated, using degreasing alkaline baths, followed by several thorough rinses.
.Prepare the bath using demineralised water and add 10 to 50 kg of FIPROCOAT 9001 for every 1000 litres of bath. Bring to working temperature and homogenise at least 15 minutes before treating workpieces.
Then add 15 to 25 kg of ALCAFIP 1051 until the pH of the working bath is stabilised for values between 4.2 and 4.8.
After treatment with FIPROCOAT 9001, the parts must be rinsed with clean water preferably demineralised water (overflow welcome) and final pass with deionised or demineralised water. FIPROPLUS 915 can be used in steps after conversion to optimise paint adhesion.
Following drying with temperature between 50 and 90°C.

Bathroom control
Please proceed as follows:
.- .
Take 50 ml of bath and transfer to an Erlenmeyer flask
. Add 6 ÷ 7 drops of phenolphthalein indicator
Titrate with NaOH 0.1N, the millilitres of NaOH 0.1N consumed indicate the concentration of the working bath.
A liquor prepared with 10 g/l of FIPROCOAT 9001 has a score, without pH adjustment, of 8.3 ml.
Adjusting the pH with ALCAFIP 1051 gives a score to be redetermined at start-up and kept as a limit.
For greater bath management accuracy we also recommend periodic zirconium point determination by complexometric titration of the solution under test.
Power supply
The correct feeding of the bath will be determined by the Fiprokim technical service depending also on the amount of overflow set.
In any case it is recommended to introduce 7 kg of FIPROCOAT 9001 for every missing zirconium point per 1000 litres of bath.
In any case it is recommended to feed continuously, using overflow to reduce pollutants and to feed according to the set pH.
