What is Polyurea?

Polyurea is a remarkable technology which can coat most surfaces, is touch dry within seconds and is super strong.

Benefits of Polyurea Coating Protection

The applied polyurea systems are noted for their superior corrosion and erosion protection for substrates, preserving the structure and the surrounding environment. As well, the coating will last longer, extending the service life and decreasing the need to generate new waste from the future surface preparation and coating work.

Polyurea cannot solve your protective coating, or joint fill needs by itself. It must be specified and installed in combination with proper surface preparation and primers, correct manufacturer’s material formulation, proper equipment, quality control inspection and trained applicators.

Benefits of Polyurea:

  • Dries within seconds
  • 100% Waterproof
  • Chemical resistant
  • Abrasion resistant
  • Weather tolerant from -20c to 300c
  • CE Certification
  • BBA Certification
  • Zero solvents
  • Minimal waste

Polyurea vs. Polyurethane

Polyurea is closely related to polyurethane. Both are two component systems made with isocyanate-based materials. However, while the second component in polyurethane is polyol resin, the second component in polyurea is a polyether amine. In terms of performance, conventional polyurethane’s require a catalyst, which is sensitive to temperature and moisture. Low temperatures can slow the reaction and moisture can interfere with the reaction causing blistering and other negative effects. Polyurea, on the other hand, does not require a catalyst. Reactivity for these coatings is fast, typically 3-10 seconds. Consequently, they can cure at temperatures as low as -20C and in the presence of moisture.

Polyurea vs. Epoxy Resin

In terms of performance, unlike polyurea, epoxies require a catalyst. They are sensitive to temperature, humidity and moisture, giving them a narrow window for application. Unlike polyurea, epoxies have extensive cure time and little or no elongation properties. This leads to frequent failure of the coating with expansion or movement of the substrate

 

Polyurea is Green

Pure polyurea contains zero solvents so the resulting membrane forms a solid, inert & non-hazardous product. Polyurea is processed in a closed system with minimal human or environmental contact. The manufacturing of the base materials is all handled at ambient temperature and pressure, requiring minimal energy input during production.

Minimal waste is generated during spraying. Pure polyurea contains no catalysts, which would remain in the environment or break down over time.

Green technology for sustainability.
