FIPROPHOS 530 is a phosphodegreaser, designed to give the treated article a conversion to iron phosphates with coating weights between 0.4 and 1.3 g / m2.
FIPROPHOS 530 consists of phosphates, surfactants, coating regulators, oxidation inhibitors and line stoppage inhibitors.
Usage and Applications
Fill the tub with clean water
Activate the system and the heating. Once the temperature of 40 ° C has been reached, proceed with point 3
Add the quantity of product necessary to reach the programmed concentration
Start the system for at least 5 - 10 'to allow the bath to homogenize
ALCAFIP 250 for pH adjustment
Control of bathing
Take 10 ml of bath to be analyzed. Place them in an Erlenmeyer flask and add 50 ml of demineralized water. Add 4-8 drops of phenolphthalein solution.
With a graduated pipette, titrate with 0.1N sodium hydroxide until a pink color appears.
The ml consumed indicates the bath score.
These values are to be considered when forming the bathroom.
Therefore it is advisable to determine the titer before adjusting the pH.
Then, once the bath has been adjusted to the correct working pH, proceed to a second determination of the score. The ml consumed will be the reference value to be maintained.
For every 1 missing point of total acidity add kg. 3.1 of FIPROPHOS 530 every 1000 liters of bath.
Deposition of a homogeneous protective substrate
Easy to start and run process
Low environmental impact and non-hazardous products
Increased hours of salt spray
Increased adhesion of paints and coatings
