Polyurea lining technology boasts excellent chemical resistance to many liquids with high build thickness characteristics, rapidly drying finishes, and very low perm ratings. It is ideal for use in a variety of waterproofing, corrosion control, immersion and lining applications, such as Tank Liners, Bed Liners, Pond Liners, and more.
Polyurea provides excellent adhesion to properly prepared surfaces. This technology is a better alternative to epoxy, polyurethane, fiberglass and other mat-reinforced lining systems. Polyurea linings combine high tensile strength and elongation properties with low permeability and high impact resistance. This makes them ideal where a tough, flexible (or hard) liner is needed.
Primary containment tanks use polyurea as a coating material, while many secondary containment structures use polyurea lining systems. In fact, many of the world’s sea aquariums turned to polyurea lining technology due to its fast-set return-to-service characteristics, its ability to achieve UV stable colors, and its superior physical properties over conventional linings.
Saving damaged infrastructure
Polyurea linings are used when an existing coating or substrate has been cracked or damaged to the point where its integrity has been compromised, and it can no longer provide adequate containment. Through the use of pre-sprayed panels, these types of issues can quickly be remedied. This saves time and money versus trying to install new infrastructure or even a more traditional protective coating.
This method of remediation is long lasting, as well, providing years of extended life to otherwise unusable assets.
Recycling polyurea linings
Polyurea linings are environmentally friendly as well, when recycled from one location to another. By cutting apart the panels, transporting them to a new location and reinstalling, a one-time investment in pre-sprayed polyurea panels can save thousands in the long run.
Polyurea linings are actually stronger and thicker at the seams, unlike traditional HDPE or sheet goods. Recycled polyurea panels can offer better protection the second and third time around. However, it’s fairly unlikely a facility owner will want to part with their polyurea lining system in the first place!
Used extensively in the water and wastewater industries, polyurea is an ideal liner for most water tanks, including salt water. Polyureas even withstand many chemical gasses produced at waste treatment plants, including harsh UV lighting used to kill bacteria. Several polyurea systems are available for Potable Water applications. Some are USDA-acceptable and NSF-approved to NSF/ANSI 61 Standard for potable water storage.
Polyureas are also recommended for lining large diameter pipes, manholes, clear wells and process tanks for potable and non-potable water, basins and reservoirs, lift stations, and reserve fire water tanks.
Polyureas contain no VOCs, and are also available in brush grade for touchup and repairs.
