Abstract

Recently, medical devices for a smart health development and dissemination are becoming increasingly frequent use of devices and their's thermal stability, durability, the external splendors are required. Industrial demand for smart health medical devices uses high-functioning electrodeposition technology that expressed pearl-like feeling is rapidly increasing. Generally, pearl powder is added to electrodeposition pigment in order to form a coating which shows pearl-like feeling. On the other hand, the electrodeposition technology for the smart health medical devices uses a new method that can express pearl-like feeling without using pearl powder. In this study, we was tried to find out the most appropriate texture formation, the right dilution recipe. We've tried various ptoportions of pigments (ED-600, ED-600S, ED-MX, ED-M). As a result, we found out that ED-600 and ED-MX (15% solid) in appropriate concentration showed the best adherence rate. By several samples tests and experiments which include washing the fixed pigment in various temperature levels (20~40degrees C) and drying, we were able to get the best results in drying condition of 180+/-10degrees C and 30+/-5 min. The research showed that it is mush more competitive and cost effective to use the new method that produces natural pearl-like feeling on the surface than to add pearl powder to high-functioning electrodeposition pigment, which is a method that has been used for the smart health medical devices so far.
