Epoxy Phenolic Lined Steel Drums

Steel drums are a versatile packaging for the transport and storage of many materials. However, there are some materials, usually liquids in the food or chemical industries, that may not be compatible with steel. In these cases, drum linings are used to protect both the contents and the drum from contact due to damage or contamination from their interaction. The drum lining most commonly used at Skolnik is an epoxy/phenolic lining.

Epoxy phenolic coatings offer consistent high quality protection for a wide range of applications. The lining is created by combining heat-cured epoxy resin with thermosetting phenolic resin. The chemical resistance from these two resins makes for an ideal lining for a container holding liquids such as food products, detergents, latex paints or other materials with a pH range above 7.

This lining has high resistance to 92%-98% sulfuric acid at temperatures up to 120 degrees Fahrenheit. The coating is also resistant to hydrochloric acid, phenol, anhydrous chlorobenzene, carbon tetrachloride and many other chemicals. An epoxy phenolic lining is also flexible. So, when applied correctly, the lining can adhere to a dent and bend with the metal, preventing any chipping or contamination of the contents.

At Skolnik, we strive to protect our clients, their materials and communities by connecting them with the right container for their contents and needs. Our lined steel drums are just one way we ensure that our drums are thicker, heavier and stronger enough to do the job. Free compatibility testing is available, and recommended, to insure content integrity.

Know your Linings

Carbon steel and stainless steel each possess properties that make them perfect containers for specific materials without any modification. But, for some materials, especially in the pharmaceutical, chemical and food industries, a drum lining is necessary. Lining is often required as a safety precaution, to meet the strict regulations of government agencies, and/or because the contents or environment would be contaminated without it. Even as a precaution, lined steel is a necessary measure to preserve the integrity of the materials, container, facility, handlers and the environment.

The most common lining for a lined steel drum is a phenolic coating. Phenolic linings provide a chemical protection between contained materials, such as food, and the metal of the drum. The phenolic is mixed with an epoxy to give it extra flexibility – this prevents it from cracking if the drum undergoes any damage. Skolnik lined carbon steel also includes a rust inhibitor to remove surface oil prior to lining. The upper tolerance for Skolnik’s epoxy phenolic lining is about 550 degrees Fahrenheit, after which the coating could become brittle and compromised.

A rust inhibitor will prevent flash rust on our unlined/uncoated drums, but if a customer needs a long-term rust resistant drum or a drum that can safely contain chemical materials, an unlined drum will not suffice.

Skolnik lined steel drums are available in a variety of different shapes, sizes, materials and lining compositions. We recommend talking to one of our sales representatives if you have any questions about your container needs, lining needs or your materials compatibility with linings.
