Abstract
A bio-based epoxy resin obtained from a reaction mixture comprising a glycidyl ether component and a bio-based component comprising a fatty acid and a rosin acid, wherein the glycidyl ether component comprises at least two epoxide groups.
Claims20
A curable composition comprising a functionalized oligomer epoxy resin and an auxiliary epoxy resin at a ratio of functionalized oligomer epoxy resin to auxiliary epoxy resin of about 10:90 to about 90:10,
- wherein the functionalized oligomer epoxy resin is obtained by reacting (i) a glycidyl ether component comprising at least two epoxide groups and (ii) a bio-based component comprising a fatty acid and a rosin acid at a molar ratio of the glycidyl ether component to the bio-based component of about 0.5:1 to about 1.5:1, thereby forming the functionalized oligomer epoxy resin.
