What is spray polyurea elastomer thechnoloty (SPUA technology)

The use of spray-applied polyurea coatings for protecting concrete, steel and  other industrial substrates from the degrading effects of corrosion and abrasion has increased dramatically. This innovative new polymer coating  technology is 100% solids, contains zero volatile  content and it is generating an extremely fast  gel time which is ideal for moist environments like those in the hydro-electric industry.The SPUA technology theory is reaction  of isocyanate with primary amine terminated polyethers(Polyesteramine PEA).

Advantages:

1.SPUA overcomes many shortcomings of traditional   application technology and make a revolutionary leap for application in site. 

2. Excellent mechanical properties and extended durability, even in extreme environmental conditions.

3.Fast, consistent reactivity that is hydrophobic  and therefore affected very little bydamp or cold surfaces. It can be sprayed directly on water or ice and has been sprayed at -20°C with minimal effect on tack free time. No catalysts are required. 

4.Excellent adhesion to a wide variety of substrates for properly formulated systems.

5.Readily compliant with regulations  limiting the levels of volatile organic compounds. 

6.Polyurea spray elastomer systems are able to meet stringent environment standards due to the 100% solids formulations. 

7.Polyurea spray elastomer  can be built up to any thickness in one application including vertical and overhead  surfaces. It eliminates the sagging, the need for multi-coat applications.  

8.Polyurea spray elastomer is characterized with good weathering, abrasion resistance, chemical and water  resistance, especially insensitivity to humidity.
