Check the listing for details. Salt for Phosphate conversion coating phosphatization, phosphatizing. Condition: New. Listed at 2.60 USD. Salt for Phosphate conversion coating (phosphatization, phosphatizing, phosphating) Compound: - Mass fraction of phosphoric acid in terms of P2O5 - 46-52% - Share of mass content of phosphates - 0.7% - The proportion of mass content of manganese - 14% - The proportion of mass content of iron - 0.5% - Total acidity not more than 25% - Substances insoluble in water no more than 6% - Loss on ignition no more than 19% Application: It is used for phosphating steel parts and products. Its solution is prepared at the rate of 30-35 grams of salt per 1 liter of water. At a constant temperature of 96-98 degrees in a special working bath, the parts withstand the set time, it is worth considering that after cooling, the phosphate film expands for another 10 minutes, so you should wait for this time after the end of the set time. The time required for a high-quality application of a phosphate film is limited depending on the need. If you need to protect the product from metal corrosion, then the exposure is carried out for 1.5 hours, if this is an insulating coating, then 35-40 minutes will be enough. Phosphate films, in which the drug salt ef is used, have increased fire-resistant and electrical insulating properties.
