New Guide Available: Dip Coating Theory - Film Thickness

Posted on Tue, Sep 11, 2018

An illustration of how the dynamics of drying in dip coating are affected by the formation of a concentration gradient and the capillary action of the dry film.


Dip coating is a popular thin-film coating method used in both academia and industry. This method involves immersing and withdrawing a substrate from solution in a precise, controlled manner - leaving behind a thin film of solution coated on to the substrate. The thickness of this resulting thin film is directly affected by the processes and processing conditions that take place during dip coating. 

Interatcions between various combinations of forces are at play during each stage of dip coating. The two stages of dip coating that have the strongest influence on the characteristics of the thin film are the withdrawal and drying stages.

Our newest guide will give you a basic overview of dip coating. This guide also provides theoretical explanations behind the factors affecting film thickness - including wet film formation,  thickness evolution, and the dynamics of drying.
