Determination of Inner Coating of Steel Drum

Users can submit various internal coatings (including non-internal coatings and iron phosphatizing coatings) by the barrel manufacturer for immersion tests under similar environmental conditions for more than 6 months and for storage and transportation. After analyzing whether the coatings have changed and whether the pigments contained in the coatings have been leached out, it is up to the user to determine the appropriate type of internal coatings. There is no mineral oil protective coating on the inner surface, please pay attention to the effect on your product.
