Is Polyaspartic Coating better than Epoxy or Polyurethane Coating?
April 26, 2018
Unless you are a resinous flooring professional or a chemist, it can be hard to differentiate between Polyaspartic, Epoxy or Polyurethane coatings. In many resinous flooring projects they are combined in a flooring system. Each one of these resins serves a purpose.
Nowadays, machine manufacturers, owners of commercial and industrial premises, car refinishing shops and other relevant decision-makers want coatings that can speed up the painting operation while at the same time deliver the high performance known from polyurethane coatings.
Is a Polyaspartic floor better than an Epoxy or Polyurethane floor?
Consider these comparisons:
- Typically Epoxy or Polyurethane floors can take 4 or 5 days to install.
- Polyaspartics can cure in three to four hours.
- Because Polyaspartics cure so fast, they can save you a bundle on labor costs.
- Epoxy resins have a tendency to yellow over time and may not be color-fast.
- Polyaspartics are UV stable and do not yellow.
- For proper curing without any curing defects, epoxy coatings must be installed at temperatures around 55 degrees F.
- Polyaspartics can be applied around freezing temperatures, making them perfect for walk-in freezers and the like.
- Epoxy resins less flexible and less abrasion resistant.
- Polyurethane coatings perform very similar to Polyaspartics but they take longer time to cure (at least 24 hours) and need to be applied very thin (4 to 6 mils per coat)
- Polyurethane coatings are used mostly top coats over Epoxy coatings. They cannot be used as a complete system in itself.
- Polyaspartic coatings can be used as top coats over Epoxy coatings (to save costs) or they can be used a complete flooring system.
The two main benefits of Polyaspartic based flooring systems are increased productivity and long-term cost efficiency. The gain in productivity over conventional coating technologies can be achieved thanks to two properties of polyaspartic coatings:
- Significantly faster drying times at ambient temperature than conventional Epoxy or Polyurethane technologies, which allows a faster return to service.
- For high film build applications, a much greater film thickness in a single cooperation is possible, which in practice means one layer can be saved.
