Coating Approvals
General Information
Please always verify yourself that the tank coating manufacurer has approved the use of the specific cleaning chemical for the coating at the time of application by checking the current website or contacting the producer of the tank coating. The verification must include the concentration, mixing ratios and application of the cleaning chemical. Furthermore a test of the cleaning chemical on your ship tanks should be carried out. Please feel free to contact us in any case of doubts or questions.
