Epoxy Tank Coating On Chemical Tankers
NO EPOXY PAINT PRODUCER WILL EVER DECLARE IN WRITING HOW MUCH ACID PH VALUE THEIR PAINT CAN ENDURE. Phenolic resins are costly They'll load solvents which cant be loaded in epoxy and polyurethane. Has better resistance to acids than epoxy or polyurethane but has poor resistance to solvents and alkalies. To enhance the natural rubber life the place solely vapour contacts, they overcoat with chlorobutyl and tank metal coming in contact with sunlight is coated silver.
Don't load any cargoes in epoxy tanks which are not allowed by the paint producer of your tank particular paint. Whereas a stainless-steel tank or zinc tank after methanol discharge is ready for next cargo. Bear in mind long term air flow of empty tank at 30 deg C is required earlier VIBRATORY POLISHING than water is launched within the tank. In case you ballast epoxy cargo tank the ballast water surface must be chased down using tank cleansing machines through the deballasting course of lest you get a stained /discoloured coating.
