Phosphoric acid
Phosphoric acid at 75% concentration, also called hydrogen phosphate, is a chemical product mainly used for the surface treatment of metals. It is used for derusting, pickling, and phosphating. Derusting refers to the removal of corrosion, and pickling to the creation of a slight roughness on the metal to create adhesion before painting. Phosphating refers to the treatment of steel by immersion in a phosphoric acid bath, with the aim of passivating the metal. The formation of iron phosphate on the surface creates protection against air and therefore against corrosion. Paint adhesion is improved.
MAIN FUNCTIONS
Phosphoric acid 75% is a mineral acid used for:
- Descaling
- Stripping, pickling
- Derusting metal parts
- Phosphating metal parts to improve paint adhesion and corrosion resistance
INDUSTRIAL USE
Phosphoric acid is used in phosphating baths for all types of surface treatment. It has a dual action: it removes rust and creates protection against corrosion.
PROFESSIONAL USE
Phosphoric acid is used for derusting, pickling, and pre-paint preparation, particularly for restoring bodywork on vintage vehicles. It is also used prior to applying a metal protection solution.
APPLICATION TIPS
Adjust the dilution of the product according to the intended application.
For derusting: dilute 10% phosphoric acid with 90% demineralized water. For phosphating: dilute 20% phosphoric acid with 80% demineralized water heated to between 60 and 80°C.
For cleaning metals before painting, use our phosphating degreaser. Thanks to its wetting action, the product acts uniformly, without immersion bath.
It is not recommended to use phosphoric acid on thin sheet metal or thin steel. Use a rust converter instead.
