The development of polyaspartic is a representative evolution of high-performance materials. Its advancement has consistently focused on addressing the shortcomings of traditional polyurea—primarily extremely short gel times, high sensitivity to temperature and humidity, and strict equipment requirements—while pursuing superior comprehensive performance and construction convenience.
Traditional aromatic polyurea, developed and commercialized by Texaco (later acquired by Huntsman) in the 1980s, featured extremely fast reaction speeds (gel times measured in seconds), excellent physical properties (elasticity, wear resistance, corrosion resistance, waterproofing), and good thermal stability.
However, the extremely short gel time (typically within seconds to tens of seconds) demanded high-temperature, high-pressure impingement mixing equipment and highly skilled operators, making large-area, complex applications or repairs very difficult. Additionally, aromatic polyurea was prone to yellowing, limiting its use in applications requiring high weather resistance.
To overcome the rapid reaction issue, chemists began exploring methods to “tame” the aggressive reaction between amines and isocyanates.
Key Breakthrough: The Invention of Polyaspartic Ester.
Core Concept: Shield the highly reactive primary amine (-NH₂) via Michael addition reaction to convert it into a less reactive secondary amine.
Technical Approach: Specific aliphatic primary amines (such as cycloaliphatic amines) were reacted with maleate or fumarate esters to create a new secondary amine-terminated resin—this is polyaspartic ester.
Technology Pioneer: Scientists at Bayer (now Covestro) achieved this breakthrough around 1990 and filed the fundamental patent. By selecting different primary amine structures (R1, R2) and adjusting molecular weight, they could precisely control steric hindrance and electronic effects, significantly reducing the reaction rate with isocyanates (especially aliphatic HDI trimer).
Based on its proprietary polyaspartic ester synthesis patent, Bayer launched the first generation of commercial polyaspartic ester resins (such as Desmophen NH 1420) around 1995, matched with its own aliphatic polyisocyanates (such as the Desmodur N series), forming the initial polyaspartic system.
Core Advantages:
Early applications mainly targeted areas requiring high weather resistance and decorative finishes, such as high-performance industrial floor topcoats (replacing yellowing-prone polyurethane topcoats) and steel structure anti-corrosion topcoats.
The material was also tested in fast-turnaround environments (like parking lots and factory workshops) thanks to its relatively quick curing (surface dry in tens of minutes to a few hours, fully cured within hours to a day).
Bayer/Covestro: Continuously introduced new generations of polyaspartic resins (such as Desmophen NH 15xx, 16xx series), further optimized through molecular design:
Competitors Emerged:
The development of polyaspartic continues, with future trends focusing on higher performance, greater sustainability, expanded functionality, lower costs, and easier application to meet ever-evolving market demands.
