Secondary containment coatings

What are secondary containment coatings, and how are they used? For large industrial enterprises, storage and transport of chemical agents is required to create new products and provide services to clients. Some of these agents are so caustic that, if left untreated, the containers in which they are stored will corrode from the inside out. This can cause leaks that allow the chemicals to spill out, damaging both the local environment and expensive company assets. One may apply a secondary coating to containers to protect them from corrosion. Crude oil, gasoline, and hydrochloric acid are all examples of corrosive agents that require special coatings to be stored safely. 

Concrete surfaces require secondary containment coatings as well. Walkways, walls and roofs made of concrete need coatings for protection against the elements: sunlight, wind, and rain. While it gives the outward appearance of something very solid, concrete is actually quite porous. If left unsealed, concrete will absorb water and other contaminants over time. This will cause it to warp and capture unpleasant odors. Once this happens, the only way to fix the issue is to tear it up and pour new concrete. This is about protecting both your investment and the safety of those who use the space.

In areas of storage for large volumes of chemicals, it is standard procedure to pour a thick, concrete slab beneath the storage containers to provide a protective layer between the chemicals and the earth below. The purpose of this coated concrete floor is to keep any spilled chemicals in place until they can be properly cleaned and disposed of. Even small spills of harsh acids in industrial settings can otherwise compromise the integrity of the slab over time. Spilt acids can corrode holes through the concrete and eventually leak into the ground soil and local water supply.

A commonly used legislative tool in environmental protection laws is expanding regulations governing heavy industries. These include worker safety regulations, restrictions on dumping, and regulations governing the storage of chemical agents. Regulations for storage of flammable and toxic compounds include requiring storage in a special climate-controlled container, using drums lined with anti-corrosive compounds. Ventilation systems to filter out toxic fumes are required in larger storage buildings to protect workers from damage to the lungs and nervous systems. Each of these specialized facilities make extensive use of secondary coatings to protect the integrity of the structures and prevent unwanted leaks.

Advances in chemistry continue to make secondary containment coatings stronger and more reliable for industrial operations, employees, and customers. Bowers Industrial takes pride in the durability and longevity of the chemical and corrosion resistant coatings that we provide. We will work to ensure satisfaction. Bowers has provided secondary coatings for the mining, power, chemical, food and beverage, and wastewater industries for over 30 years. We also proudly provide services to the United States military.
