Summary of the Dip Coating System
Process by the Dipping Method
It is the method of keeping a specimen vertically and dipping it into set Dip Coating Liquid, then raising-up from the liquid to upper portion and gelling of the attached liquid film in air (vapor phase).

Dipping a specimen into Dip Coating Liquid tub perpendicularly | |
Starting of raising-up with using mutual interaction of Viscous of Dip Coating Liquid, Surface Tension and Gravity. | |
The Raising-up Speed of specimens controls the thickness of the film, from relationship with the viscosity of the Dip Coating Liquid and the Gravity which flows down adhered liquid. | |
Completed to form uniformed thin film -- Dryness |
Relations of Raising-up Speed and the Film thickness
It will control the film thickness by Raising-up Speed and the Solvent Consistency.
The slower speed of Raising-up will make the thinner Film,
The higher speed of Raising-up will make the thicker Film.
The slower speed of Raising-up will make the thinner Film,
The higher speed of Raising-up will make the thicker Film.
