Polyaspartic polyurea is a member of the polyurea family and represents its third generation. Evolving over the years, polyurea technology has witnessed the advent of aromatic spray polyurea (first generation), aliphatic spray polyurea (second generation), and now, polyaspartic ester polyurea.
Aspartic ester, a groundbreaking aliphatic series, is characterized by its slow-reactive, high-performance, and eco-friendly attributes. First introduced by Bayer in 1990 as a reactive diluent for polyurethane coatings to reduce VOCs, it has found applications in heavy-duty, waterproof, and wear-resistant flooring among other high-end domains.

Polyurea coatings adopt a one-time coating process. It is also a dust-free polyurea coating with strong adhesion, friction resistance, and hardness. No matter how large the area is, there is no joint.
Polyurea coatings offer remarkable durability, versatility, and efficiency across various applications. Below are the key attributes that make these coatings stand out:
Polyurea is a thick, clear polyester coating. This will dry out quickly and become brittle. Polyurea is closely related to aromatic polyurethanes. When applied to concrete floors, the surface looks like glass—making it a popular choice for garage floors that require a high gloss finish. However, it can dry quickly if the floor installer needs more time to disperse or level the coating over the entire floor evenly.
Adding a flexible aliphatic compound to polyurea produces polyaspartic acid, further delaying the curing process. This way, installers who want to apply a coating design such as chip, vinyl flake, or stain can add it together. In addition, it helps the coating to disperse on top.
Comparison of properties between feiyang polyaspartic and polyurethane:
| Property | Polyaspartic polyurea | Polyurethane |
| Environmental property | Environmental friendly, construction solid content 70%-100% | Poor environmental protection, construction solid content 30%-40% |
| Reaction speed curing | Curing time adjustive, 20min-4h, typically cure above -15℃ | Low reaction speed, request curing temperature above -5℃, curing time more than 24h in normal temperature adhesion |
| Adhesion with substrate | Don’t need primer, the adhesion with carbon steel substrate is beyond 14Mpa, the bonding with concrete reach 4.5Mpa. | Need primer, adhesion with carbon steel substrate less than 8MPa, adhesion with concrete is 2.5 Mpa |
| Weather resistance | QUVA test space 4000h | QUVA test is 1000h at most film-film |
| Film thickness one | One time construction film 50μm—1mm | One time construction film 50μm—100μm |
| Mechanical properties | Rigidity hardness 2H, elongation 400%, tensile strength 25MP | Rigidity hardness 2H, elongation 400%, tensile strength 3MPa |
| Construction | Multiple construction method, get rid of the restriction of specified equipment same | Same as aspartic polyurea. |
Comparison of properties between feiyang polyaspartic and epoxy:
| Polyaspartic | Epoxy |
| Insensitive to temperature changes. Standard construction can occur under -15 ℃ -40 ℃, humidity ≤ 85%, and rapid drying (30min-5h). | Low-temperature construction is complex, and heating and other means are required to assist the structure. Solidifying at low temperatures (more than 48h) is challenging. |
| Good color retention and UV resistance, no discoloration or chalking after 15 years of outdoor use | Poor color retention and UV resistance, easy to crack, warp, and delamination |
| The rigidity and elasticity are adjustable. The rigid material has not only good hardness but also has a certain flexibility. | Only tough coatings can be prepared and have poor flexibility |
| Excellent wear resistance and impact resistance or poor | Poor impact resistance and wear resistance are easy to delaminate under a slight change of external force. |
Polyaspartic coatings boast an adjustable curing time, ranging from 20 minutes to 4 hours, and remain stable even at temperatures as low as -15℃. With exceptional color retention and UV resistance, these coatings can last outdoors without discoloration or chalking for up to 15 years.
In summary, aspartic polyurea coatings offer a myriad of benefits including eco-friendliness, durability, and versatility, making them a strong contender in the coatings industry.
