This invention relates to bio-based polyfunctional carboxylic acids reacted with vinyl ether compounds to form liquid vinyl-blocked bio-based polyfunctional carboxylic acids. These liquid vinyl-blocked bio-based polyfunctional carboxylic acids can be mixed with a polyfunctional vegetable oil-based epoxy resin to form a homogeneous curable coating composition. Upon curing at elevated temperature, thermoset coatings are formed which have excellent hardness, solvent resistance, adhesion, and flexibility. The invention also relates to the use of a curable coating composition comprising at least one polyfunctional vegetable oil-based epoxy resin and at least one vinyl-blocked bio-based polyfunctional carboxylic acid, which may be coated onto a substrate and cured thermally. Methods of making the vinyl-blocked bio-based polyfunctional carboxylic acids and curable coating compositions and substrates containing the same are also disclosed.
本发明涉及生物基多功能羧酸与乙烯醚化合物反应形成液态乙烯基阻滞生物基多功能羧酸。这些液态乙烯基阻滞生物基多功能羧酸可以与多功能植物油基环氧树脂混合形成均质可固化涂料组合物。在高温下固化后,形成具有优异硬度、耐溶剂性、附着力和柔韧性的热固性涂层。本发明还涉及至少包括一种多功能植物油基环氧树脂和至少一种乙烯基阻滞生物基多功能羧酸的可固化涂料组合物的使用,可涂覆在基底上并通过热固化。还公开了制备乙烯基阻滞生物基多功能羧酸和可固化涂料组合物以及含有它们的基底的方法。
