What is Polyurea Coating?

According to the Polyurea Development Association polyurea is defined as...

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).

Benefits of Polyurea Coating

• Durable Coating
• Weather & water proof
• Remains Flexible (elastomeric)
• Resistant to various solvents, acids & caustic materials
• Weather Tolerant
• Cures at -25ºF to >300ºF Even in High Humidity
• Excellent Resistance to Thermal Shock
• Waterproof, Seamless, and Resilient
• Some Systems are USDA and Potable Approved
• Spray, Hand Mix and Caulk Grade Materials
• Excellent Bond Strengths to Properly Prepared Substrates
• Resistant to Various Solvents, Caustics and Acids
• Low Permeability, Excellent Sustainability
• Rapid Cure Time = Short Down Time
• Very Tough and Durable Coatings
