Definition - What does Polyaspartic mean?

Polyaspartics are materials that are considered to be a subset of polyureas. Specifically, the term is usually used to refer to aliphatic polyureas. Polyaspartic floor coatings are typically two-part systems that consist of a resin and a catalyst to facilitate the curing process. While early polyaspartic coatings possessed several limitations, modern formulations are used as alternatives to epoxy and polyurethane coatings.

Corrosionpedia explains Polyaspartic

When formulated in coatings, polyaspartics possess properties that fall between polyurethane and epoxy coatings systems. In other words, they are hard enough to resist scratches, yet flexible enough to absorb moderate impacts. These properties make polyaspartic coatings ideal for areas with medium to heavy foot traffic, such as airports, malls, hospitals, shopping centers, etc.

Another benefit of this material is its customizability. Polyaspartic esters can be added to coating formulations to manipulate drying times and pot life. This allows some polyaspartic coated floors to be returned to service as early as the next day.
