Polyurea is an elastomer formed by the rapid reaction of isocyanates with polyamines. It cures extremely fast, without the need for catalysts, and develops excellent toughness, elongation, and chemical resistance.
Polyurea is synthesized by combining isocyanates (aromatic or aliphatic) with diamine curatives or chain extenders. The reaction is moisture tolerant and applied mainly through spray techniques.

Polyurethanes are versatile polymers formed by the reaction of isocyanates with polyols, often modified by chain extenders and catalysts. They can be flexible, rigid, or elastomeric depending on formulation.
Polyurethanes are produced by combining diisocyanates (MDI, TDI, etc.) with polyether or polyester polyols. The use of catalysts and chain extenders controls the cure rate, mechanical properties, and processing window.

Epoxies are thermosetting polymers formed by the reaction of epoxide groups with curing agents (amines, anhydrides, or organometallic compounds). They are known for strong adhesion, chemical resistance, and dimensional stability.
Epoxy resins are typically synthesized from bisphenol A (BPA) and epichlorohydrin. They are cured using hardeners or catalysts, which determine final mechanical and thermal properties.
