Title:
ELECTRODEPOSITION COATING COMPOSITION CONTAINING STARFORM SURFACTANT
Document Type and Number:
Japanese Patent JP2008248064
Kind Code:
A
Abstract:

To provide an electrodeposition coating composition having defoaming tendency and also suppressing drying unevenness of its own.

The electrodeposition coating composition having defoaming tendency and also suppressing drying unevenness of its own is obtained by including 0.05-10 wt.%, preferably 0.1-5 wt.%, especially preferably 1 wt.% of a starform surfactant based on cationic or anionic electrodeposition coating resin solids. When the surfactant is at less than 0.05 wt.%, the defoaming tendency is insufficient, on the other hand, when at greater than 10 wt.%, the defoaming effect becomes saturated, being meaningless.
