CG 1500 is a complex corrosion inhibitor formulation that is effective in preventing corrosion in both sweet and sour systems. It is non-emulsifying and will form a tough and persistent protective film on all metal surfaces. CG 1500 is both oil soluble and water dispersible. It can be used in a wide variety of systems as part of a corrosion prevention program. It can be fed on a batch basis to protect oil well tubing and flow-lines, and can be applied neat to protect production equipment.
