Polyurea is a coating, lining and joint sealant technology. It is being used successfully for any different applications today. Polyurea coatings and linings are more commonly applied over concrete and steel for corrosion protection and abrasion resistance. They also have tremendous advantages over conventional materials for joint fill and caulk applications due to their fast set nature, high elongation and durability/abrasion characteristics. Polyurea can be molded and shaped by spraying it into molds. Similarly, polyurea is also used as hard coat protective shell over expanded polystyrene (EPS) for architectural molded fascia applications. The markets and applications are endless and on the rise.
Polyurea by name is not a specific coating system or a specification; it is a description of a polymer technology. A great technology that boasts many different formulations and physical property ranges. There are pure polyureas and hybrid polyurea systems, each possessing their own characteristics, advantages and disadvantages. Users and specifiers must take into consideration that the proper combination of formulation, spray equipment, surface preparation, primers, training and application procedures is what leads to polyurea success. Improper training, under-rated equipment and lack of material/substrate compatibilities and preparation is what leads to polyurea failure, and for that matter, failure of any protective coating and lining system. Always follow the system manufacturer's written guidelines for the best results.

Polyurea Definition
A polyurea coating / elastomer is that derived from the reaction product of an isocyanate component and a resin blend component. The isocyanate can be aromatic or aliphatic in nature. It can be monomer, polymer, or any variant reaction of isocyanates, quasi-prepolymer or a prepolymer. The prepolymer, or quasi-prepolymer, can be made of an amine-terminated polymer resin, or a hydroxyl-terminated polymer resin.
The resin blend must be made up of amine-terminated polymer resins, and/or amine-terminated chain extenders. The amine-terminated polymer resins will not have any intentional hydroxyl moieties. Any hydroxyls are the result of incomplete conversion to the amine-terminated polymer resins. The resin blend may also contain additives, or non-primary components. These additives may contain hydroxyls, such as pre-dispersed pigments in a polyol carrier. Normally, the resin blend will not contain a catalyst (s).
