2-methyl-1,3-propanediol a New Monomer for High Solids Polyesters

Research output: Contribution to journalConference articlepeer-review

Abstract

2-methyl-1,3-propanediol (MPDiol) was studied as an improvement over the currently used neopentyl glycol (NPG) in polyester coatings' resins. A direct substitution of MPDiol for NPG was made, along with a partial replacement of adipic acid by isophthalic acid. The properties of the resulting polyester resins were studied. The performance of high solids coatings made with these resins was evaluated at two different melamine levels. The results indicated several advantages to MPDiol. Among these are its liquid form, asymmetry of the monomer, reduced crystallinity when polymerized, and a shorter cook time. Performance tests indicated an improvement in flexibility over the NPG based coating.
