Polyurea is a type of polymer that is becoming a popular alternative to polyurethane, epoxy, neoprene, and similar compounds. This compound comes from a chemical reaction between isocyanates and a given resin blend. Polyurea is organic in nature, and does not generally contain hydroxyl groups, setting it apart from similar rubber-like compounds.
In practical use, this new compound is remarkable for its self-healing properties. Due to lengthy bonds between molecules, the finished material can often seal itself back together after being scratched or torn. This makes the compound popular for railroads, pipe coatings, marine usage, and various roof coatings. It is also commonly found in floor coatings meant for shops and garages due to its resiliency.
