Among the curing hardeners for powder coating, β-hydroxyalkylamide is widely used due to its easy handling, excellent exterior durability, good mixing with other chemicals, flexibility, hardness, and especially non-toxic property. In this study, β-hydroxyalkylamide which is normally produced by oil bath heating was synthesized by microwave heating system. For synthesis, it takes 300 min of reaction time for heating system of oil bath but the microwave heating requires only 100 min of reaction time because of the internal heating. Performances of products obtained by both heating systems showed very similar properties. These results suggest that the microwave as a heating source is an effective tool for the reaction of β-hydroxyalkylamide.
