WHAT IS POLYUREA?


The polyurea system is made up of polyether-amines or an amine terminated polyol.  This polymer is reactive and does not need a catalyst (it is an auto catalytic polymer).  This reactivity (or gel time) is characteristically fast (in the 4-5 second range) and cures well on cold surfaces.  Reactivity is also so fast and preferential that. Polyureas in general are moisture insensitive and do not react with humidity and moist substrates.

The polyurea system has one disadvantage in that it has a fast gel time making it difficult to use where applications require a smooth surface or a delay is required to allow the coating to flow into those hard to reach areas and corners.


POLYUREA APPLICATIONS

Polyurea and can be applied to virtually any required thickness in one application. Premium Pure Polyurea are not usually multi coat systems. This results in very fast application and turnaround times.  Hybrid Polyurea is more susceptible to moisture and has a longer "gel time" because of the addition of cheaper polyurethane components.


PIPE LINING Polyurea Pipe Lining

As with polyurethanes, polyurea can also be applied after the pipe has been manufactured, the benefits being that there are no hefty infrastructure costs to manufacture pre-lined pipes.

Polyurea can be sprayed on site or in remote locations; still giving the premium protection required for connections and field joins.



Polyurea Bund

BUND COATINGS

Polyurea (especially Pure Polyurea) is the perfect solution to apply a premium protective seamless membrane for an existing bund whether that bund be an earthen or a manufactured substrate.




WATER, WASTE WATER AND SEWERAGEPolyurea Waste Water Treatment Works

The water and wastewater industry requires a corrosion protection system that is able to withstand the corrosive environment often experienced in municipal infrastructure. As with polyurethanes, Rhino Linings has specially formulated premium 2:1 and 1:1 pure polyurea.  They are far superior to other hybrid or modified polyurea, and provide excellent chemical, impact and abrasion resistance, adhesion, and resistance to cathodic disbondment and undercutting.
