Industrial Coating Overview

Coating is a technique that can be used for bonding objects, adding new functions, and optimizing surfaces by wetting the surface of the target (substrate or target) with various adhesives or materials. The technique has been adopted for various applications in many industrial fields.

Wettability and contact angle

Wettability is a major concern for coating processes.

When the contact angle θ shown as A in the figure is closer to 0, the wettability is higher.

The purposes of coating in manufacturing can be divided into two major categories: adhesion and functionalization/surface processing.

This section describes the overview, types, and mechanisms of coating for these purposes.
