A novel polyol synthesised from castor oil by aminolysis and a partially blocked toluene–diisocyanate blocked with N , N ′‐diethyl lactamide was used to prepare an urethane. This was used in different weight proportions to modify epoxy amine adduct to give binders suitable for cathodic electrodeposition. The pigmented composition of these binders based on the iron oxide (natural) and titanium dioxide (rutile) gave coatings with improved performance.
