METALFIP 329

PRODUCTS DESIGNED FOR THE REMOVAL OF THE SURFACE LAYERS OF OXIDE AND CONTAMINANTS

Technical features

METALFIP 329 is a liquid product for deoxidizing and degreasing the surfaces of aluminum and its alloys before their chemical treatment.
The chemical composition is based on inorganic acids and non-ionic surfactants in aqueous solution.

Control of solutions

The control of the bath is carried out by determining the total acidity:

  • Take 10 ml of bath

  • Pour them into a flask / beaker

  • Add 40-50 ml demineralized water

  • Add 4-5 drops of phenolphthalein indicator

  • Titrate with sodium hydroxide (NaOH) 0.1 N until colorless to persistent pink.

The consumption in ml of 0.1 N NaOH for toning represent the total acidity and the bath score which for a preparation with a concentration of 20 g / l is about 15.5.
It is also always necessary to check the aluminum content in the solution.
The check must be done as follows:

  • After determining the total acidity, add 1-2 grams of sodium fluoride NaF to the same sample and shake for about a minute.

  • Titrate with 0.1 N hydrochloric acid until a colorless solution is obtained, persistent for at least one minute. Consumption in ml of 0.1 N hydrochloric acid provides the aluminum score.

Alimentation

  • Removal of thermal oxides (calamines) from raw materials or semi-finished products

  • Removal of processing oxides and oily residues or emulsions

  • Etching, pre-painting, pre-conversion treatments

  • Burnishing and satin finishing

  • Final cleaning of the finished product, with preservation of tolerances

Precautions

All parts in contact with METALFIP 329 solutions must be in AISI 304 or 316 stainless steel or structural carbon steel coated in PVC or polyethylene or polypropylene or polyfluorinated plastics.

For the transport, storage, handling and discharge of wastewater, follow the indications and laws in force.
Avoid improper handling of the packages that can cause product spillage.
Protect from frost, store away from heat sources and direct sunlight, keep containers tightly closed.
