Purpose:
The concentrate is used for anticorrosive treatment of steel surfaces. It is also used to improve adhesion of applied varnish and paint coatings. The three-cation phosphating composition forms a modifying zinc phosphate coating on the steel surface.
Used In:
- machine-building
- instrument-making
Technical characteristics of the concentrate and the phosphate coating produced from it:
Appearance | Transparent or slightly turbid liquid |
Density at 20 °C, g/cm3 | 1.45–1.55 |
Concentration, g/l | 24–30 |
Phosphate(P2O5) mass portion, % | 18–21.5 |
Zinc and nickel mass portion, % | 10.5–13.5 |
Nitrate (NO3) mass portion, % | 4.5–6.5 |
Common acidity, a.u., points | 17–24 |
Free acidity, a.u., points | 1.5–4 |
Working temperature, °C | 30–35 |
Treatment time, min | 2–10 |
Coating mass, g/m2 | 1–6 |
Corrosive stability (Akimov test), min | 2–5 |
Safety requirements:
The concentrate is a hazardous substance. It is necessary to work in rubber gloves and eye protectors
Storage:
- in specified by technical conditions closed container at the temperature not lower than 10 °C
- the storage warranty period is 2 years from the production date
Advantages:
- high quality anticorrosive properties of fine-crystalline zinc phosphate coating are obtained at low temperatures (30–35 °C)
- decrease of the sludge formation
- cost reduction
- high stability of the concentrate during storage and phosphate treatment
- improvement of the ecological compatibility of phosphate treatment due to the reduction of the amount of sludge
- simplicity of equipment
- technologies of the phosphating concentrate application for corrosion inhibition are material saving and resource saving
Implementation:
The concentrate has been tested at the Industrial Enterprise MTZ, corporation Atlant (Minsk) and at some other machine-building and instrument-making enterprises in Russia
Forms of cooperation:Signing a contract to produce the concentrate
