FIPROPHOS 546

PRODUCTS FOR SURFACE CONVERSION AND PRE-PAINTING

Technical features

FIPROPHOS 546 is a liquid formulation based on alkaline phosphates used to degrease and simultaneously phosphate iron and steel surfaces before their painting. The coating obtained consists of iron oxides and phosphates and its weight is generally between 0.2 and 0.4 g / m².
FIPROPHOS 546 can also be used to degrease parts of aluminum, zinc and their alloys.

Usage and Applications

FIPROPHOS 546 should be used in aqueous solution, by spray, with the following operating parameters:

Treatment time: 1 ÷ 3 minutes
Usage temperature: 40 ÷ 60 ° C
Concentration: 10 ÷ 40 g / l
Bath score: 7.2 ÷ 28.8 points of total acidity (to make-up without pH adjustment)
pH of the bath at 20 ° C: 4.5 ÷ 5.3

Preparation of the solutions

For every 1000 liters of solution use 10 to 40 kg of FIPROPHOS 546.
Fill the tank with water and bring it to working temperature; then add the predetermined amount of FIPROPHOS 546 with the pumps in motion and circulate the solution for at least 10 minutes before the first material to be treated enters.
The Fiprokim Technical Service will provide the optimal conditions for use when starting the system.

Concentrazione

Control of bathing

Take 20 ml of sample, add 4-5 drops of phenolphthalein indicator and titrate with a 0.1 N sodium hydrate solution until a constant pink color.
The number of ml of 0.1 N sodium hydrate used represents the bath score which, for a 10 g / l preparation, must be equal to about 7.2.

Alimentation

  • 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

  • Preconversion or final treatment

Warnings

All parts in contact with FIPROPHOS 546 can be built with AISI 316 L steel, avoid yellow alloys in pumps and valves.
Store the product in its original packaging, in a cool and dry place, protect from frost.
