Precision at its Finest
Based on the two primary factors that dip coating is susceptible to, there are two basic kinds of dip coating defects; Defects brought about by dip coater instability or a change in withdrawal speed and defects brought on by “external” elements like the environment the substrate is covered in or the viscoelastic and chemical characteristics of the ink.
The liquid is drawn away from the substrate and back toward the bath by draining forces. Entraining forces, on the other hand, aim to keep fluid on the substrate. The thickness of the wet film deposited onto the substrate is determined by the balance between these two sets of forces.
The process of dip coating is rather simple. It is necessary to optimize variables like withdrawal speed in order to produce films of a good caliber. The quality of the film is also greatly influenced by atmospheric conditions, such as temperature, airflow, and cleanliness, which must be continuously controlled during the dip coating process.
Solid surface free energy is one of the basic physical properties like density, melting point, refractive index, dielectric constant, modulus, etc. Measuring the solid surface free energy has applications in paints, coatings, and adhesives, semiconductors, printing, aerospace, mining, pharmaceutical and many more industries. To give an insight, high surface energy material is more reactive and stickier.

The first step of dispersion and dissolution of a powder is wetting; therefore, understdanding the wettability behavior of powders is important in many applications such as inks, paints, food and pharmaceutical industry. The method to characterize powder wettability depends on the powder properties and application purposes. Sessile drop, Wilhelmy plate and liquid penetration (both column and thin film wicking) are common methods for determining the wettability of powders.

Only few contact angle goniometers provide the back to front tilt of the camera. This feature enables the user to perfectly see the contact point. It also enables the software (Jikan Assistant) to automatically pick the contact points.
