It doesn't work. Why?

Whe customers have difficulty with COBRATEC^® products, we ask them:

• What concentration is being used?
  Depending on the particular industrial use, the concentration of COBRATEC^® will vary. Using the improper concentration can lead to less than desired protection. For a list of recommended use concentrations, click on applications.
• Are you using COBRATEC^® for copper protection?
  The primary use of COBRATEC^® is for copper protection. However, protection of steel and aluminum are possible using the new COBRATEC^® 900 series or combinations of COBRATEC^® and other corrosion inhibitors. For more information click on the multi-metal protection.
• What else is in solution?
  The use of other components in solution can have a direct affect on the performance of COBRATEC^®. For example, problems can occur if there is a high level of ammonia used in a cleaning solution or with a metal based biocide in a metal working fluid. This type of problem should be discussed with the Technical Service Department.
• What temperature is the process?
  This question is related to direct treatment applications of copper. To receive the best possible protection when treating copper strip, decorative copper, copper wires of printed circuit boards involves a balance of COBRATEC^® concentration, treatment temperature and time of treatment. For further information contact the Technical Service Department.
• How is the COBRATEC^® being applied?
  This is another question generally related to direct treatment of copper. The application of COBRATEC^® by spray or tank dip can give dramatically different results. Contact Technical Service for more information.
• What is the pH?
  The pH of a solution has a direct affect on the corrosion of any metal. For example, the corrosion rate of copper and copper alloys increases significantly below a pH of 3.5. Metal protection in an active pH region for an alloy may require additional amounts of COBRATEC^® to achieve the desired results.
