Water Corrosion Inhibitor
| Description: | Recently, engine cooling systems have become a problem because of a change in the solder used to build them. Because of the porosities of metals, a softer solder containing more lead and less tin is now being used. It is much more subject to corrosion unless additional coolant protection is given with the right kind of chemicals. | | Composition: | Many radiator problems have caused confusion when equipment operators have been told that the filter being used contained too much DCA and not enough MBT. DCA means “dry chemical additive”, which means any additive contained in the filter itself. These filters or any DCA do not contain much if any, MBT, or sodium mercaptobenzothiazole which is necessary in a concentration in order to prevent early corrosion in newer coolant systems. 626-P Enviro-Cool contains MBT in enough concentration to provide effective protection. Engine manufacturers have recognized the problem to a degree and now protect the solder in new systems temporarily, but problems will occur later if the owner does not service the cooling system properly.
Maintenance people should realize that the chemicals furnished in coolant filters are flushed from the filter and depleted in a very short time. The filter will continue to remove contaminants, but additional chemical protection is needed for adequate protection.
| | Performance Characteristics: | While some anti-freezes contain corrosion inhibitors, they may only be effective against a certain metal, for example, steel. For this reason, anti-freeze alone is not sufficient for protecting against corrosion of all the dissimilar metals found in the cooling system. This is also true of the summer anti-rust compounds found in the cooling system. The use of tin, lead, copper, copper alloys, brass, and aluminum make 626-P Enviro-Cool a necessity for suitable protection of the cooling system. | | Environmental Considerations: | 626-P Enviro-Cool is environmentally friendly because it greatly prolongs coolant life and reduces flushes as well as the content of lead and other hazardous metals in the coolant due to corrosion. Furthermore, engines operate more efficiently when cooling systems are properly maintained, keeping exhaust emissions closer to engine design specifications. 626-P Enviro-Cool is toxic to fish the first 24 hours of dilution; however, Aquatic Toxicity Tests show that 626-P Enviro-Cool begins to detoxify immediately after dilution. | | Uses: | 626-P Enviro-Cool should be used in the original coolant of any new engine before corrosion has a chance to begin. To correct the problem once it has started, clean and flush the entire cooling system with a good chemical cleaner to cut corroded solder.
Install a new filter and use 1 liter of 626-P Enviro-Cool for each 32 liters of coolant capacity. For regular maintenance, 1 liter should be added for each 160 liters of capacity every 250 hours. If the system has a filter it should be changed at this time.
626-P Enviro-Cool used as recommended will protect the radiator and when the cooling system has been properly maintained, it will prevent hard-water scale, control foaming, reduce oxygen content, control electrolysis and cavitation erosion, neutralize acids, prevent corrosion and lubricate the water pump. Enviro-Cool should be added directly into the circulating system of the cooling water.
| | Applications: | --Corrosion inhibitor for anti-freeze, coolants, and water-based cutting oils. | --Corrosion inhibitor in air conditioning and refrigeration systems. | --Metal deactivator for various alloys. | --Rust inhibitor for cooling systems. |
| Note: | To maintain full strength, do not store in direct sunlight in glass containers. This product is not an anti-freeze. Keep from freezing or mix with anti-freeze. If frozen, allow to thaw out. Chemical action will not be harmed. |
