Preparation and Evaluation of Epoxy Binders Based on Rosin as Organic Coating for Steel

In this work, modification of rosin as epoxy organic coating was reported. Epoxy resins were prepared from modified rosin, rosin Diels-Alder adducts, rosin formaldehyde and their ketone. These adducts were reacted with epichlorohydrine in the presence of NaOH as a catalyst to produce epoxy resins. The preparation of the curing agents for the epoxy resins based on rosin poly (amideimide) was investigated. The recent advances in manipulating patterned rosin arrays and patents are reviewed with a focus on the progress of production of epoxy resins based on biopolymer and natural products and their epoxy organic coating applications.
