The polyurea is a synthetic polymer obtained from the reaction of a diamine with a diisocyanate, polymerization reaction is very similar to the polyurethane one, but in the case of polyurea, the resulting link is a "urea", so it is called polyurea.

Polyurea coating technology constitutes a more recent and advanced system than the traditional ones used in waterproofing and protective coating applications.

The technology is based on the reaction of an isocyanate component with an amine blend. The isocyanate can be of aromatic or aliphatic composition. This reaction is rapid, proceeding to completion within a few seconds, thus requiring specialized mixing and application equipment to be used by a specialized application crew.
