Technical specifications
METALFIP 303 is a specific phospho-decorating agent for paint lines, to be used where a strong deoxidising action combined with a phosphating action is required.
METALFIP 303 is formulated with low foaming and is therefore suitable for use in spraying machines even at temperatures of 40 °C. It effectively removes machining, protective and moulding oils from metal surfaces while developing a phosphate coating that is ideal for paint anchoring.

Usage and Applications
METALFIP 303 is normally used at concentrations between 20 and 70-90 g/l by volume and temperatures between 40 and 60° C. Special additives such as Fiproplus 701 can be added to increase the degreasing power and duration of the solutions.

Controlling solutions
Check and adjust the solution's pH within the suggested range, then titrate according to the procedure:
Take 10 ml of the solution to be analysed and place it in the glass beaker (or Erlenmeyer flask), add 20 ml of distilled water
Add 5-8 drops of Phenophthalein indicator. The solution will appear colourless
. Titrate the solution obtained, keeping it stirring, with NaOH N/10 until a PINK colour is obtained
This colouring identifies the end of the titration
.
Power supply
To obtain the concentration in gr/lt, multiply the value obtained by the fixed number 1.43
. Then bring the concentration to the required value.
