A polyurea coating / elastomer is that derived from the reaction product of an isocyanate component and a resin blend componet. The isocyanate can be aromatic or aliphatic in nature. It can be monomer, polymer, or any variant reaction of isocyanate, 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 ???? 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. Thes additives may contain hydroxyls, such as pre-dispersed pigments in a polyol carrier. Normally, the resin blend will not contain a catalyst(s).
Polyureas were first developed in the early 1980's for automotive fascia applications due to their high strength and impact resistance. These systems were fast reacting and utilized an expensive reaction injection molding(RIM) process to make body parts. The first sprayable polyureas hit the market in the late 1980's as a plural-component system that could be applied using less expensive, portable and commercially available eauipment.
