Abstract
Epoxy curing agents used in epoxy powder coating are substituted DICY (Sub-DICY), accelerated DICY(Acc-DICY), Pyromellitic anhydride(PMDA), trimellitic anhydride(TMA) and Phenolic curing agent(Ph.C.A). The aim of this study was investigated reaction kinetics and cause of deviation in reaction rate measured by variable reaction rate measuring device such as DSC, ICI cone&plate viscometer, gel time tester and Rheovibron OPAⅢ according to various curing agents.

에폭시계 분체도료에 사용되고 있는 경화제로는 치환 dicyandiamide(Sub-DICY), 촉진 dicyandiamide(Acc-DICY), PMDA(Pyromellitlc dianhydride), THA(trimellitic anhydride ), phenolic curing agent(Ph.C.A.) 등이 있다. 본 연구의 목적은 5가지의 에폭시 경화제로서 에폭시 분체도료를 제조한 후 일반적으로 반웅속도를 측정하기 위해 사용되또 있는 DSC, ICI cone&plate 점도측정기, gel time 측정기, Rheovibron OPAⅢ 등의 측정기기를 이용하여 경화제 종류에 따른 reaction kinetics를 세밀히 관찰하고 측정기기에 따른 반응속도 차이점을 비교하여 그 차이점에 대한 요인을 분석하였다.
