The paper, titled, Bio-Based Succinic Acid: A versatile Building Block for Performance Driven Polyurethane Dispersions and Coatings, was co-authored by Professor Dean Webster and Post-Doctoral Candidate Ivan Hevus and co-workers of North Dakota State University (NDSU) and Dr. Niek Zweep of Stahl International Performance Coatings of Waalwijk, Netherlands.

The paper summarized a study of the performance features using bio-based succinic acid based polyols as part of a polyurethane dispersion and coatings application. The investigation found that when bio-based succinic acid replaced adipic acid, the resultant polyester polyol influenced the solvent, abrasion and flexibility of the resultant PU coating.

The work conducted cooperatively between BioAmber Inc. and NDSU investigated the PU coatings on a rigid metal substrate whereas the work conducted using a similar system by Stahl was designed for flexible automotive fabric. In both cases, the performance testing found the succinic acid-based systems improved the abrasion and solvent resistance and was on par with adhesion, wash resistance and hydrolytic stability when compared to the adipic acid bases control.
