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).

Advantages:
l        Non-catalyst, rapid curing, and not-sagging.
l        Moisture and temperature insensitivity during processing.
l        Two component, 100% solids, No VOC’s.
l        Excellent physical properties.
l        Have good thermal stability.
l        Good adhesion to variety of substrates.
l        Wide formulation flexibility aromatic and aliphatic system.
l        Reinforcement incorporation.
l        Easily pigmented.
l        Easy of application, spray, pour or rim.
