Polyurea Chemistry
Learn the chemistry of polyurea coatings with an industry-leading tensile strength, one of the most robust protective materials on the market.
Overview of Polyurea
Polyurea coatings are comprised of two basic components: a base and a hardener. They are derived from the chemical reaction of isocyanate and amine resin combined. This reaction typically occurs within a few seconds, so polyurea is quickly and expertly applied using state-of-the-art technology.
Polyurea has an industry-leading tensile strength, making it one of the most robust protective materials on the market. In the right environment and with proper maintenance, polyurea can last over 30 years before it needs touching up, repairs, or replacement.
Polyurea Chemistry
Polyureas are reaction products of isocyanates and amines. These resin systems often compete with polyurethanes in similar coating applications. Like urethanes, they exhibit high flexibility, durability, and chemical resistance, which are superior to most polyurethanes. The main difference between these two technologies is that amine-terminated (-NH2) resins are used rather than hydroxyl-terminated (-OH) resins. The reaction of the amines with isocyanates results in the formation of urea linkages (-NH-CO-NH-).
Polyurea's Strong Molecular Bond Advantages
Highly Durable and Flexible
Polyurea is a lot stronger than traditional coating materials like epoxy and polyurethane. It provides unmatched flexibility, can withstand high and low-temperature variations, and can be applied year-round regardless of weather conditions.
Easy to Clean and Maintain
When fully cured, polyurea provides a smooth, flexible, yet durable, solid surface that's easy to clean and maintain – able to withstand sanitization and power washing, ideal for food manufacturing and healthcare facilities.
Consistent Long-Lasting Results
With proper maintenance and regular cleaning, a polyurea coating can last 30 years or more before needing repairs or replacement.
Excellent Chemical Resistance
Polyurea coatings provide a fast-curing, durable, and flexible protective barrier that prevents water damage and harmful chemicals, and is resistant to petroleum-based and caustic chemicals.
Strong Waterproofing Capabilities
One of the main applications of polyurea is waterproofing structures such as concrete flooring, roofing systems, balconies, terraces, parking garages, and wastewater facilities.
Environmentally Friendly
Polyurea is 100% solids with no solvents or VOCs, which makes it environmentally friendly.
Easy Application and Rapid Curing
Polyurea is evenly applied using a specialized plural-component spray system. Once sprayed onto the surface, the polyurea cures within seconds, minimizing downtime and returning the structure to use much faster than other waterproofing coatings.
