Cationic UV-cured coatings of epoxide-containing vegetable oils

Vernonia oil (VO), an epoxide containing vegetable oil, and epoxidized soyb ean oil (ESO) have been used to formulate cationic ultraviolet (UV) cured c oatings. The compatibility of VO or ESO with other coating ingredients affe cts their incorporation levels into cationic W-curable coating formulations . Cationic-UV-cured VO and ESO coatings exhibited excellent adhesion, impac t resistance, UV stability, gloss retention, and corrosion resistance prope rties. Pencil hardness and tensile strength of coating films decreased with increasing oil content. (C) 1999 Elsevier Science S.A. All rights reserved .
