Polyurea
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 chicago #72 jersey 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 chicago #72 jersey as hard coat protective shell over expanded polystyrene (EPS) for architectural molded fascia applications. The markets and applications are endless and on the rise.
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.

Markets and Applications for Polyurea spray
Pipe / Pipeline Coatings & Linings
Polyurea Coatings and linings are increasingly being used to protect steel pipes from corrosion. Polyurea has demonstrated its ability to last longer than paint and maintenance services and costs are reduced. Polyurea is a great protective coating system for pipes that are insulated with polyurethane foam. Polyureas are also being used to line the inside of water and sewer pipes for infrastructure rehabilitation work.
Bridge Coating
Polyurea's ability to outlast paint and fight off corrosion is a major reason these systems are being specified for bridge deck and structure coating by chicago #72 jersey State DOT's around the nation. The most common applications of polyurea coatings on bridges are over steel and concrete.
