Letter From Covestro Explaining Polyaspartic Naming Nomenclature


  • Polyaspartic Aliphatic Polyurea

    Letter from Covestro AG on 10/7/2019 titled "Polyaspartic naming nomenclature".

The letter from Covestro, formerly Bayer MaterialScience, reads:

"Polyaspartic naming nomenclature:

Per your request, we will clarify the differences between polyaspartic and polyurea. The name polyaspartic has recently become popular among formulators in the industry due to the need to differentiate these polymers from polyureas and polyurethanes. By definition, a polyaspartic polymer is an aliphatic polyurea because it is the reaction of an aliphatic polyisocyanate with an aliphatic diamine - the polyaspartic ester."

Todd Williams, Technical Service, Covestro AG

Key Takeaway - Polyaspartics Are Aliphatic Polyureas

Polyaspartics are a type of polyurea, an aliphatic polyurea to be exact. The name polyaspartic was used in order to differentiate it from conventional polyureas which are aromatic chemistries and from older polyurethane polymer technologies. Aliphatic and aromatic compounds are different and can be of importance to you if your floor is going to be exposed to sunlight. We will discuss these at greater length in the weeks to come.
