Use WSC 8180 DP corrosion inhibitor is a non-toxic corrosion inhibitor for use in closed cooling water systems. It finds direct application in process cooling, hot water and chilled water systems, and glycol-water systems. Corrosion inhibition by WSC 8180 DP is a surface chelation reaction between the inhibitor and the metal surface. The highly impermeable film inhibits both anodic and cathodic reactions. Even in multi-metal systems, WSC 8180 DP prevents galvanic attack. The formation of the film takes place in a relatively short period of time and is accelerated by heat transfer conditions. The resultant surface-metal complex is not easily removed and exhibits inhibitory action, even if WSC 8180 DP is lost from the system for moderate periods of time.
Features Composition : a blend of organic based corrosion inhibitors. Appearance : clear yellow to brown liquid Density (kg/m3) : 1023 pH : 6.2 These data are to be seen as typical values and should not be considered as specifications. Feeding WSC 8180 DP inhibitor is fed as delivered to give a concentration of 1200 - 4000 mg/lt in the system. It may be slug-fed to a closed system or may be metered continuously to maintain an adequate concentration in the treated system. Best results are obtained at a pH range of 6.5 - 7.0 although control of pH to a range of 6.0 - 8.0 will give excellent corrosion inhibition.
Handling precautions Wear suitable protective gloves and safety goggles. Avoid contact with eyes, skin and clothing. In case of contact immediately flush with plenty of water. After eye contact seek medical advice. In case of spillage, absorb with inert material and sweep up. Then flush the area with plenty of water. Before use review the Material Safety Data Sheet for additional information.
