Liquid-O-Ring 690 Aqua Cure is a water-soluble, corrosion inhibitor designed for metal surfaces that have been exposed to salt water and other brines. Liquid-O-Ring 690 Aqua Cure provides fast, temporary protection to pipe used in drilling and workover operations. The clear film of Liquid-O-Ring 690 Aqua Cure has fast-acting properties, which severely retard the affects of salt water and other salts such as chlorides and bromides on tubulars. It has been well documented that common brines have an extremely corrosive effect in well operations. It is clear that sodium chloride (NaCl), calcium chloride (CaCl2), sodium bromide (NaBr), calcium bromide (CaBr2), potassium chloride (KCl), potassium bromide (KBr), and zinc bromide (ZnBr2) are very corrosive. When these salts are combined, it greatly accelerates the effects of corrosion (flash rusting) on the pipe. In addition, well temperatures above 200°F (93°C) and well pressure greatly increase the degree and rate of corrosion. Liquid-O-Ring 690 Aqua Cure inhibits the corrosive effects of various salts in aqueous solutions when exposed to ferrous metal surfaces. Liquid-O-Ring 690 Aqua Cure is specifically formulated to stop or retard the effect of these highly corrosive brines on pipe. It is designed to be used immediately after the pipe is placed on the rack after coming out of the hole. Liquid-O-Ring 690 Aqua Cure does not contain chlorides. The Liquid-O-Ring 690 Aqua Cure protective film is recommended for reducing internal and external corrosion on the pipe.
