Fatty acid based waterborne epoxy ester resins for coating applications

High performance water soluble epoxy ester resin was synthesised by partially reacting bis-phenol A based epoxy resin with different fatty acids.

The resultant epoxy ester resin was then reacted with diethanol amine. These resins were characterised by FTIR, NMR, DSC and TGA. Further, the prepared epoxy esters were neutralised using phosphoric, lactic, acetic and hydrochloric acids to make them water soluble.

Excellent anticorrosive properties

Mild steel panels were coated with the water soluble epoxy ester resins and their performance were evaluated by monitoring adhesion, tensile, scratch hardness, bend and impact resistances. The corrosion resistance properties of the coatings were evaluated by salt spray, seawater immersion and electrochemical impedance spectroscopy. It is observed that phosphoric acid neutralised tung oil fatty acid based epoxy ester has better mechanical and anticorrosive properties than the rest of the water soluble polymers.

The study is published in: Progress in Organic Coatings, Volume 87, October 2015, Pages 95–105

Epoxy Resins

Thanks to their excellent characteristics, epoxy resins belong to the most established binders within the coatings industry. This new book explains the basic principles of the chemistry of the epoxy group and imparts the use of epoxy and phenoxy resins in industrial coatings, such as anticorrosive coatings, floor coatings, powder coatings and can coatings, with the help of concrete formulations. Essential for any formulator of competitive modern paint systems!
