Epoxy Tank Coating On Chemical Tankers

Epoxy Tank Coating On Chemical Tankers

NO EPOXY PAINT MANUFACTURER WILL EVER DECLARE IN WRITING HOW MUCH ACID PH VALUE THEIR PAINT CAN ENDURE. Phenolic resins are costly They can load solvents which cant be loaded in epoxy and polyurethane. Has higher resistance to acids than epoxy or polyurethane but has poor resistance to solvents and alkalies. To improve the pure rubber life where only vapour contacts, they overcoat with chlorobutyl and tank steel coming in contact with daylight is coated silver.

Do not load any cargoes in epoxy tanks which are not allowed by the paint manufacturer of your tank particular paint. Whereas a chrome steel tank or zinc tank after methanol discharge is prepared for next cargo. Bear in mind long term ventilation of empty tank at 30 deg C is required before DESCALING water is introduced within the tank. In case you ballast epoxy cargo tank the ballast water floor should be chased down using tank cleansing machines through the deballasting process lest you get a stained /discoloured coating.
