Most people know polyurea coatings are great for industrial structures such as underground pipelines and water tanks. Still, it is often overlooked just how ideal they are for secondary containment systems.
What is secondary containment?
Secondary containment systems establish an extra line of defense if something happens to the primary containment system. For instance, if a storage container that holds wastewater should happen to break, the secondary system will prevent any liquid from spilling out and destroying the environment. It's a temporary action that protects the environment until the proper actions can be taken to fix the primary system. If you work with hazardous chemicals, you might know quite a bit about these systems.
Polyurea coatings are fantastic for any secondary containment system, in particular:
- Oil and gas well systems
- Chemical facility systems
- Storage area systems
- Tank farm systems
- Petroleum storage systems
- Sump and trench systems
- Drum storage areas
But how can a polyurea coating act as a secondary containment system?
Polyurea solutions are not only impervious to water but also very flexible. The coating forms a leak-proof barrier that prevents any material inside the primary containment unit from escaping. So if it's a record-setting cold day and everything feels tight, the polyurea will prevent cracking. The same goes for a sweltering heatwave record kind of day, where everything doubles in size. The polyurea will still keep everything in place.
Polyurea coatings are resistant to water deterioration, such as corrosion or rust. But that's not the only weather element that can do some damage. Ultraviolet exposure can affect a storage tank. For example, if you have a polyethylene tank, constant exposure to UV light can make the material brittle, leading to cracking. However, this doesn't happen to a polyurea solution.
Some businesses use rubber linings, paints, or other surface protectors as a secondary containment system. But that can lead to issues such as:
- A rubber lining doesn't last nearly as long as a polyurea coating.
- There may be weaknesses in these types of coatings that a chemically aggressive fluid can exploit
- A rubber coating doesn't have the same abrasion and corrosion resistance.
- They can be expensive as compared to a polyurea solution.
- There's a possibility that a rubber lining can absorb and release materials that cause contamination.
At ArmorThane, we know how critical it is to protect the environment from hazardous materials. And the best way for an industry to do that is to use the best type of protection available. That protection is a polyurea solution.
