Steel Drum Coatings & Linings: Universal Solution for Wide pH

This article was previously published on 8/7/2023 and updated on 10/2/2024

The steel drum is one of the most versatile and widely used containers in the industrial world. From chemicals and solvents to food-grade materials and oils, the storage requirements for different industries vary greatly. Ensuring that the contents of these drums are not only safe but also protected from contamination and degradation is paramount. At the heart of this protection lies the interior lining of the drum.

Drum linings are crucial because they act as a barrier between the drum’s metal surface and its contents, ensuring that corrosive substances, food-grade materials, or hazardous chemicals are safely stored. Choosing the right lining can directly affect the longevity of the drum and the integrity of the materials stored within it.

Why Are Drum Linings Important?

Drum linings provide critical protection against corrosion, chemical reactions, and contamination. Metal drums, especially those made of steel, are prone to rust, which can degrade the drum itself and affect the materials being stored. Linings ensure that:

  1. Corrosion is Prevented: Steel drums that store corrosive materials must have a reliable barrier to prevent rust from forming.
  2. Product Purity is Maintained: Especially in the food materials sector, any contamination can lead to product spoilage or safety risks. Linings help preserve the integrity of these sensitive materials.
  3. Extended Drum Lifespan: Proper linings can significantly extend the life of a drum, ensuring its repeated use for multiple storage and transport cycles.
  4. Chemical Reactions are Minimized: Some substances stored in steel drums can react with the metal. Linings serve as an inert barrier to prevent such reactions.

Diverse Applications: A Lining for Every Industry

The range of applications for steel drums is vast. Some sectors require highly specialized coatings to meet stringent safety and regulatory requirements. Common industries that rely on drum coatings include:

  • Food & Beverage Ingredients: These drums must meet stringent FDA standards such as CFR 175.300 ensuring that the linings are food-safe and prevent any contamination.
  • Chemicals: Drums storing chemicals require high levels of resistance to both acidic and caustic substances. In these applications, linings that offer broad chemical resistance are essential to prevent degradation of both the container and its contents.
  • Pharmaceuticals: Similar to the food industry, the pharmaceutical sector demands absolute purity in its products, and any contamination could pose a serious health risk. Linings used in pharmaceutical drums must meet these high standards.

RESCO® Universal Lining: A Game-Changing Solution

Our ground-breaking RESCO® Universal lining provides superior chemical resistance that spans a wide pH range. This innovative solution allows manufacturers to use a single interior lining for all products, removing the need to source different linings for various applications. Whether the material stored is acidic or caustic, RESCO® Universal ensures top-tier protection without compromise.

In addition to its versatile chemical resistance, RESCO® Universal is designed for high-heat curing, making it an ideal solution for drums that undergo more extreme curing processes. This lining is perfect for industries that require reliable performance in challenging environments, providing peace of mind for manufacturers and material handlers alike.

Rust Inhibitors (RI’s)and Additional Coatings

UNICHEM also offers rust inhibitors in both waterborne and solvent-based systems. Rust Inhibitors are used to prevent rust on the steel coils, and sheets, or sprayed into uncoated drums in storage, protecting the metal substrate before the final coating processes. RI’s also offer an extra layer of protection, where rust and corrosion prevention is critical, particularly for drums exposed to environmental elements or that store materials prone to oxidation. These inhibitors add an extra layer of protection to metal surfaces, preventing corrosion before it even begins.

In addition to rust inhibitors, UNICHEM provides a comprehensive range of drum coatings and pail linings that cater to various industry needs. These coatings can be tailored for high-heat or low-heat curing, depending on the operational requirements. This flexibility ensures that manufacturers can choose the optimal solution based on their production processes.
