This study introduces the use of 1,3-Propanediol (1,3-PDO) in polyurethanes as a building block component of polyester and polyether polyols, and as a chain extender. The bio-based coatings prepared in this investigation provided useful physio-mechanical properties, chemical resistance, and water resistance compared to reference commercial petroleum-based two-component PUDs.
Cast elastomers based on PDO-sebacate polyol exhibit an excellent combination of tensile properties, abrasion resistance, thermal, hydrolytic, and solvent resistance, as well as adhesion to metal substrates. These are desirable properties for cast elastomers intended for applications as protective coatings for pipes, and coatings for sieves typically used in drilling and mining applications.
