Lüster EcoFactory phosphating products: professional guide for pre-paint treatment
A practical guide to Lüster EcoFactory phosphating products: use, dilutions, contact time and consistent pre-paint treatment steps.
Why use a zinc phosphating product before painting
In the pre-paint treatment of metalwork and metal components, a zinc phosphating product is used to create a uniform anchoring layer on the surface. This step supports the adhesion of paints and powder coating and helps make the process more consistent.
The Fosfatanti category in the Lüster EcoFactory line is designed for this application: zinc salt treatment, standardized bath parameters and the same yield from batch to batch. A uniform pretreatment also helps improve corrosion resistance, including salt spray resistance.
Step-by-step professional use
Prepare the bath at the indicated concentration by mixing the product with water. The parts to be treated should then be fully immersed so that the entire surface is exposed evenly to the bath.
The recommended contact time is 5–10 minutes at 50–60 °C. After treatment, rinse thoroughly with water and dry the parts, so the surface is properly prepared for the next stage of the coating process.
Dilutions and actual solution yield
For ordinary use, the indicated dilution is 20–30 ml per 1 litre of water, with a yield of 33–50 litres of ready solution. For intense use, the dilution is 40–50 ml per 1 litre, with a yield of 20–25 litres of ready solution.
In professional operations, concentration should be selected according to the process and kept consistent. Correct, stable dilution helps maintain standardized bath parameters and repeatable results from one batch to the next.
Laboratory advice for consistent application
To obtain a uniform anchoring layer, four points matter most: correct concentration, full immersion, respect of contact time, and bath temperature between 50 and 60 °C. Even small operating variations can affect treatment consistency.
The product is intended for use at every phosphating operation in the process. For supply planning, it is available in 25 kg packs and 200 kg drums.
