RXSOL-20-2061 ORG - 8 Cleaning Chemical Cleaner for zinc and epoxy based tank coatings. ORG -8 will clean and upgrade coated cargo tanks after cargoes such as leaded gasoline, gasoline blends containing MTBE, carbon tetrachloride, methylene chloride as well as virgin naphtha.It will in a cost effective way remove lead, hydrocarbons, chloride, sulphides etc. from the pores of zinc silicate and epoxy coatings. It has been designed with a pH value of 5.5 for safe application on these types of cargo tank coatings. The ordinary cleaning method with a synthetic soap takes a long time and is insufficient in removing the described contaminants. A week acid solution in combination with synthetic soap gives a much better cleaning result. ORG -8 is used as a final cleaning procedure when the cargo tanks have to be completely free of lead, chlorides, sulphides or MTBE prior to loading of special high purity cargoes.
