Lc 252 is designed to be used for “passivating” open & Closed loop systems to prevent corrosion. It is a liquid blend Of nitrite and other corrosion preventives which protects not Only steel surfaces but also copper and other metal as well. The high concentration makes it a cost effective nitrite based Passivating agent with the added advantage of being multimetal Compatibility and thus do not require separation of Non-ferrous parts from a system during passivation. Application Normally injected into the system that is previously filled with standard industrial Grade water and circulated continuously under required pressure for about 1-2 Hours with hourly monitoring of the nitrite concention. A higher temperature help to Accelerate the passivating process and therefore reduce operation time. An Appropriate temperature suitable to the system and available resources is choosen Between 35 – 950c Dosage Initial : 1 : 400 is suitable in most cases of passivation processes operating at Optimum temperature between 50 – 700c. Depending on the quality of water used Some adjustment in the amount may be required to maintain the ph of the solution. An increase in concentration of lc 252 is necessary in badly soiled systems. Additional amount of lc 252 may be required to be added during the circulation for The passivation process in order to maintain the required control parameters while Monitoring. Handling & precaution Avoid contact with acid, ammonium salts and activated carbon. No respiratory Protection. Is required, however, maintain adequate ventilation. Use rubber gloves And safety goggles when handling. Packaging Available in pail of 20 lt.. Can also be custom packaged.
