Polyurea Tank Linings | Coatings

There are different blends of Polyurea available for tank linings depending on the containment requirements. The most important attributes are chemical resistance and flexibility.

Water | Wastewater:

Water and wastewater industries use Polyurea tank linings. They can withstand most chemical and chemical gasses produced at waste treatment plants. Adding anti-microbial additives to the polyurea decreases the microbial growth on the lining. Polyurea coatings form a seamless membraneThey conform to poles, pumps and other internal structures. Large diameter pipes, manholes and lift stations are perfect candidates for Polyurea. Polyurea is available in hard structural formulations that reinforce pipes and manholes. Since sprayed on linings conform precisely they make the perfect structural coating.

Potable Water:

Polyurea is the perfect liner for water and salt water tanks. It is available in USDA-acceptable and NSF-approved to ANSI-NSF 61 standard for potable water storage. It does not leach materials into or from water. Since it is seamless it provides a protected environment for drinking water.
 

The practical uses are endless. The video playing in this section shows a mobile tanker truck that we lined. We've done many of these trucks and a common problem we see is the tank cracks where it attaches to the frame.

Since the polyurea is flexible and has over 300% elongation it is the perfect solution for severe duty applications.

Chemical Containment:

Tanks are one of the most common things you find in industry. The shapes and sizes are endless. You'll find them above and below ground. Made out of plastic, steel, concrete and an endless array of other compositions. Some are open and some sealed. Tanks are stationary while others are portable but one thing is for sure, put something in them and the deterioration starts. Something as harmless as water will cause steel to rust away. It will cause concrete to crumble as it goes through freeze - thaw cycles. Put more aggressive liquids in and the process happens faster.
 
The solution is to isolate the tank from what it's holding. A common tank coating is Epoxy. The problem is; Epoxy is hard and it has very little elongation making it prone to cracking. Polyurea is flexible, has 100%-300% elongation and is resistant to a wide array of chemicals.
