We have developed an electrodeposition coating (e-coating) which have high throwing power and can optimize film thickness distribution on body-in-white in order to reduce coating usage. The new e-coating material can control the film thickness on outer panels, while keeping the equal film thickness on inner panels as the conventional e-coating material by plasticizer optimization into main resin backbone. The new e-coating can reduce approximately 11 % of the usage from the conventional one.
