Chemtex’s Passivation Chemical is an alkaline blend of passivation chemical that is biodegradable and non-inflamable.
Chemtex’s Passivation Chemical neutralizes and passivates the metal surface after acidic cleaning, pickling, descaling or derusting of metal surface. It inhibits the chances of flash rusting that happens when the acidic and un-passivated metal surface gets exposed to air (oxygen).Application and Dosage
Chemtex’s Passivation Chemical is used at a concentration of 4-5% w/w for acidic surface passivation and pH neutralization. It is always recommended to rinse the system with plain water once after descaling or acid pickling before adding Chemtex’s Passivation Chemical to the solution.
Chemtex’s Passivation Chemicals hould always be poured into water and not vice versa.
In case of descaling operation, if the system is to be left idle for more than a day, then it should be filled & soaked with 1% Chemtex’s Passivation Chemical solution for metal preservation. While, in case of post-pickling passivation and neutralization, the bath pH should be maintained above 10.0Handling measures and precautions
