The invention provides highly functional epoxy resins that may be used themselves in coating formulations and applications but which may be further functionalized via ring-opening reactions of the epoxy groups yielding derivative resins with other useful functionalities. The highly functional epoxy resins are synthesized from the epoxidation of vegetable or seed oil esters of polyols having 4 or more hydroxyl groups/molecule. In one embodiment, the polyol is sucrose and the vegetable or seed oil is selected from corn oil, castor oil, soybean oil, safflower oil, sunflower oil, linseed oil, tall oil fatty acid, tung oil, vernonia oil, and mixtures thereof. Methods of making of the epoxy resin and each of its derivative resins are disclosed as are coating compositions and coated objects using each of the resins.
本发明提供了高度功能性环氧树脂,可用于涂层配方和应用中,但也可通过环氧基团的开环反应进一步功能化,从而产生具有其他有用功能的衍生树脂。高度功能性环氧树脂是由具有4个或更多羟基/分子的多元醇的植物或种子油酯的环氧化合物合成的。在一种实施例中,多元醇是蔗糖,植物或种子油被选自玉米油、蓖麻油、大豆油、红花籽油、葵花籽油、亚麻籽油、松油脂肪酸、桐油、菊芋油和其混合物。公开了制备环氧树脂及其每个衍生树脂的方法,以及使用每个树脂的涂料组合物和涂层物品。
