Secondary containment coatings play a vital role in preventing environmental damage and ensuring the safety of stored liquids. These coatings are specifically designed to contain any leaks or spills, providing a protective barrier to prevent hazardous materials from contaminating soil, groundwater, or other nearby areas. In this blog post, we will explore the importance of secondary containment coatings, their types, applications, and advantages.

What is secondary containment?

Secondary containment refers to the measures taken to control and contain any hazardous substances that may leak or spill from primary containment systems such as storage tanks, drums, or pipelines. The primary containment system is the first line of defense against leaks, while the secondary containment system acts as a backup to prevent any potential leaks from causing harm to the environment or human health.

The purpose of secondary containment coatings

Secondary containment coatings are applied to the floors, walls, and other surfaces of containment systems to provide an additional layer of protection against leaks and spills. These coatings are designed to be chemically resistant, impermeable, and durable, ensuring that they can withstand the corrosive effects of the stored liquids and any potential leaks or spills.

Types of secondary containment coatings

There are various types of secondary containment coatings available in the market, each designed to cater to specific needs and applications. Here are some of the commonly used secondary containment coatings:

1. Epoxy Coatings: Epoxy coatings are widely used in secondary containment applications due to their excellent chemical resistance and durability. These coatings create a strong, impermeable barrier that can withstand a wide range of chemicals and protect against leaks and spills.

2. Polyurethane Coatings: Polyurethane coatings are known for their flexibility and resistance to abrasion, making them ideal for secondary containment applications that require frequent movement or impact resistance. These coatings provide excellent protection against leaks and spills while maintaining their integrity even in harsh environmental conditions.

3. Polyurea Coatings: Polyurea coatings are known for their fast curing time and high tensile strength, making them suitable for applications that require quick installation and excellent resistance to mechanical stress. These coatings are highly durable and provide superior protection against leaks and spills.

Applications of secondary containment coatings

Secondary containment coatings find applications in a wide range of industries where there is a need to store or transport hazardous materials safely. Some of the common industries that utilize secondary containment coatings include:

1. Chemical Industry: Chemical storage tanks and pipelines require secondary containment coatings to prevent leaks or spills that could result in environmental damage or fire hazards. These coatings provide a reliable barrier against chemical corrosion and containment breaches.

2. Oil and Gas Industry: Storage tanks, pipelines, and secondary containment systems used in the oil and gas industry are subjected to extreme environmental conditions, making the need for reliable secondary containment coatings even more critical. These coatings protect against leaks, corrosion, and atmospheric damage.

3. Manufacturing Facilities: Many manufacturing processes involve working with hazardous materials that need to be stored safely. Secondary containment coatings are used to ensure that any leaks or spills are contained and do not pose a risk to the environment or the workforce.

Advantages of secondary containment coatings

Secondary containment coatings offer numerous advantages that make them an essential component of any containment system:

1. Environmental Protection: The primary purpose of secondary containment coatings is to prevent environmental damage by containing leaks and spills. By providing a reliable barrier, these coatings help protect soil, water bodies, and the overall ecosystem.

2. Safety: Secondary containment coatings also play a crucial role in ensuring the safety of personnel working with or in proximity to hazardous materials. By containing leaks and spills, they minimize the risk of accidents, fires, and exposure to harmful substances.

3. Regulatory Compliance: Many industries are subject to stringent regulations governing the storage and transportation of hazardous materials. Secondary containment coatings help businesses comply with these regulations and avoid potential penalties or legal issues.

4. Longevity: Secondary containment coatings are designed to be highly durable and resistant to various chemicals, corrosion, and mechanical stress. They have a long service life and can withstand harsh environmental conditions, providing long-term protection against leaks and spills.


Secondary containment coatings are a crucial component of any containment system, providing an additional layer of protection against leaks and spills. Their use ensures environmental protection, enhances safety, and helps businesses comply with regulatory requirements. With various types of coatings available, it is essential to choose the right one for specific applications and ensure proper installation and maintenance. Investing in high-quality secondary containment coatings is not only a responsible choice but also a sound investment in the long-term sustainability of any operation involving hazardous materials.
