Polyaspartic versus Epoxy?
Which Flooring Coating is Best for Your Project?
Polyaspartics, also known as polyureas, and epoxies are two types of floor coatings widely used in the construction and renovation industry, but they differ in their chemical composition, properties, and applications. The experts at L’Artisan du plancher offer a brief comparison to help you make your choice.
Chemical Composition
Polyaspartic (or polyurea)
Polyaspartics are synthetic polymers that are often used as curing agents in floor coatings. They are generally derived from aspartic acid and can be modified to obtain different properties.
Epoxy
Epoxies are thermosetting polymers that contain epoxy groups. They typically consist of an epoxy resin and a hardener, which chemically react to form a durable solid.
Adhesion and Resistance
Polyaspartic (or polyurea)
Polyaspartic coatings generally offer excellent adhesion to substrates, as well as chemical and scratch resistance.
Epoxy
Epoxies are also known for their good adhesion and chemical resistance, but they may be more susceptible to scratches and wear in certain applications.
What are the Curing Times?
Polyaspartic (or polyurea)
Polyaspartic coatings generally have a shorter curing time compared to epoxies, which means they can be applied more quickly and require less downtime.
In terms of durability, polyaspartic (or polyurea) retains its clarity. It is also elastic, resistant to cracks due to concrete movements.
Drying time: 6 hours to walk on the surface and 24 hours to park a vehicle.
Epoxy
Epoxies may have a longer curing time, which may require a longer period without traffic after application.
In terms of durability, “epoxy can yellow and deteriorate under UV rays.
Drying time: Can take up” to 5 days to dry after the last coat
Flexibility
Polyaspartic (or polyurea)
Polyaspartics can offer some flexibility, making them suitable for surfaces where structural movements are expected.
Epoxy
Epoxies are generally more rigid and less flexible than polyaspartics.
Applications
Polyaspartic (or polyurea)
Due to their rapid curing time and chemical resistance, polyaspartics are often used in environments where quick return to service is necessary, such as industrial facilities, parking lots, warehouses, etc.
Epoxy
Epoxies are commonly used in a variety of applications, including commercial and industrial floors, as well as surface coatings for countertops, bars, and tables.
In summary
While both polyaspartics (or polyureas) and epoxies are popular floor coatings offering various benefits, they differ in their chemical composition, curing times, flexibility, and specific applications. The choice between the two will depend on the specific project requirements and application conditions.
