Abstract
Modified epoxy resins comprising the reaction product of a cycloaliphatic, polycyclic and/or aromatic biomass derived compound and an epoxy resin are disclosed. Aqueous dispersions and coatings comprising these reaction products are also disclosed.
Claims29
A modified epoxy resin comprising the reaction product of a cycloaliphatic, polycyclic and/or aromatic biomass derived compound having less than two epoxy reactive functional groups and an epoxy resin.
A cationic electrodepositable coating composition comprising a modified epoxy resin comprising the reaction product of a cycloaliphatic, polycyclic and/or aromatic biomass derived compound having less than two epoxy reactive functional groups and an epoxy resin, wherein the biomass derived compound does not comprise rosin and/or a residue of rosin that forms part of the cationic resin backbone.
