Abstract
Paints for electrodeposition as components of forming films are limited to only several kinds of water soluble synthetic resins.
This study was pursued for the coating by electrodeposition of our traditional urushiol solution, which is a kind of alkyl phenol resin paints.
Urushiol was dispersed in polar solvents such as H2O and CH3OH.
The urushiol polymer film formed by electrodeposition was dried at room temperature or by heating.
In these experiments, the rate of electrophoresis was determined and the state of colloidal suspension of urushiol was observed under microscope; then, the relationship between the above two phenomena was discovered.
Furthermore, conditions for the electrodeposition of urushiol were determined in these experiments, and it was recognized that the physical and chemical properties of the polymer film formed on steel could be applied to practical utilization.
