Cationic ultraviolet curable coatings from castor oil

Coatings formulated from castor oil glycidyl ether (COGE), epoxy resin UVR 6100, and photoinitiator UVI 6990 produced smooth coatings with excellent gloss and good flexibility, adhesion, gloss retention, and water resistance. Formulations containing up to 50% COGE afforded promising coating performance attributes. (C) 2000 John Wiley & Sons, Inc.
