JEFFSOL^® is a biodegradable, VOC-exempt propylene carbonate, or PC, solvent (CAS No. 108-32-7) primarily used in coatings, paint strippers, surface cleaners, and degreasers. Since propylene carbonate is a high-boiling liquid with a high flash point, it is a useful tail solvent replacement in paints and coatings for PCBTF, otherwise known as Oxsol 100, which has been scrutinized for its labeling as a carcinogen. JEFFSOL^® may also be used as a slow-evaporating diluent for isocyanate curatives and prepolymers used in 2K polyurethane coatings. It has a slow evaporation rate and high flash point, making it less flammable than other common VOC-exempt solvents, such as acetone. JEFFSOL^® may also be used as a chemical intermediate to produce various commercially important materials through carbamate formation, hydroxyalkylation, transesterification, and more.
