Why We Offer Both "lined" And "unlined" Steel Drums
As a child, you probably heard your mother telling you not to buy a food can that was dented. She was right! In order to protect food from coming into contact with metal, food cans used to be coated internally with a phenolic lining. This lining was brittle and if the can was dented, it was likely that the interior lining had cracked. Today, linings offer the chemical protection of the phenolic plus they are mixed with the flexible properties of epoxy. Together, these epoxy/phenolic coatings are chemically resistant and able to adhere to a surface when it is damaged. While the epoxy/phenolic is a sprayed-on and cured coating (like paint) a passive rust inhibitor is applied to all our carbon steel drums in order to remove surface oil prior to painting. The rust inhibitor is much like the final rinse at a carwash, it is a light clear spray that is neither visible or measurable once it is applied. The purpose of the rust inhibitor is to prevent flash rust on uncoated carbon steel. If a customer needs an epoxy/phenolic lined drum for chemical or long-term rust resistance, then an unlined drum will not suffice. Please contact me, or your sales representative, if you have questions about our lining options.
What is the heat tolerance for epoxy phenolic lining, and what occurs above the tolerance temperature?
Thanks, Brett
Brett,
After checking with our lining manufacturer, they informed me that the upper tolerance for the epoxy phenolic lining would be about 550 F, at which point the coating would become brittle.
Let me know if you have any further questions.

What is the best lining option for toluene/1-pentanol solution?

Dear Irwan,
Thank you for visiting the Skolnik blog and posting your question. While we do offer drums with protective epoxy/phenolic linings, we cannot recommend product compatibility with each lining.
In this situation, what I suggest, is that I have have our lining manufacturer contact you to set up a Compatibility Test Series. The Series would involve accelerated testing of samples of your product in different lining sample cups. With most products, conclusive test results are available within 30 days. If you would like to proceed with such testing, please contact me at: 773.735.0700 x 1500.
Thank you,
Howard Skolnik
