Uneven application of coating agents significantly affects the appearance or functionality of products.
Conventionally, however, sensory evaluation is often used, and it is quite difficult to visualize such unevenness.
Quantification
Using the All-in-One Fluorescence Microscope BZ-X800
Coating agents, which are mixtures of multiple materials, can be visualized to enable easy quantitative analysis of the diameter, area, and ratio of particles.
This microscope has been used as one way of confirming the optimal mixture.
