Polyurea Advantages • • Fast Set. Can Be Walked on in Seconds No VOC's and Little to No Odor Some Systems are USDA and NSF Approved Weather Tolerant: Cures at 25ºF to 300ºF and in High Humidity Excellent Resistance to Thermal Shock Place in Service Immediately Flexible: Bridges Cracks Waterproof, Seamless and Resilient www. pda-online. org • • Unlimited Mil Thickness in One Application Spray, Hand Mix and Caulk Grade Materials Excellent Bond Strengths to Properly Prepared Substrates Resistant to Many Solvents, Caustics and Mild Acids Low Permeability Can be Top-Coated for Added Features Texture Can be Added for Slip Resistance

Polyurea Definition • 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). www. pda-online. org
