Polyurea is a coating technology/product and has been used very successfull for many different applications all around the world. Polyurea technology is not new, it has been around and in use for almost four decades now but in comparison to many other coating systems it is more advanced than some traditional coating systems and offers a whole array of advantages to the owner/contractor that cannot be achieved with other coating systems.
Polyurea is not a specific coating system by name or specification but it is a polymer technology with a wide range of product formulations that are matched to a particular requirement.
There are not many coating systems that can compare to Polyurea when it comes to attainable physical properties e.g. high elongation, superior tensile strengths, excellent abrasion resistance, high impact resistance, excellent chemical resistance.
Polyurea’s major benefit has to be its fast set and return to service characteristics, Tack free within 10 – 60 Seconds and open to traffic within the hour, returning an area to service many times faster than traditional coatings.
Polyurea needs a primer for porous surfaces e.g. concrete, cement, brick etc.
Polyurea has excellent elongation and is ideal for waterproofing the outside of basements and tanks etc. where resistance to high positive pressure and the ability to accommodate building movement is important to the effectiveness of the waterproofing.
For tanking jobs a Polyurea system is highly puncture and abrasion resistant and ideal where backfill and consolidation is part of the project.
Polyurea is sprayed using plural component spray equipment at +70C.
