KYOWA offers products that will assist you with Analysis/Evaluation Qualitatively and Quantitatively from the perspective of Interface Science for various Characteristic Features required in the Coating Process flow.
 
This includes common measurements of “Wettability”, “Adhesion”, “Surface Tension”, “Dispersion” and “Emulsion”
 
KYOWA has created, improved, and evolved unique measuring techniques and product since our establishment in 1947.
 
Our measurement and evaluation technologies are utilized to optimize functional raw materials. Our landmark achievements helped the rapid the evolution of flat panels, semiconductors, and Nano-technologies.
 
In the mass production of functional raw materials, the wet-coating process is widely being used heavy use. From the start to finish of the coating process flow it is essential to control and properly identify interfacial troubles that may occur in and between raw materials.

Functional Raw Materials are mostly powdery substances such as fillers and nanoparticles before being built into the finished products. Fine-grain dispersion liquids after the kneading process are to be applied to substrates to form coating films through many different kinds of coating methods.
 
To obtain the most appropriate coating condition and quality of the coating film it is vital to find the best-suited solvent and substrate. This also aids in the feedback control of finished films in pre- and post-processes.
 
KYOWA always reaches out to our customers to continually find new ways to improve Wetting, Adhesion, Surface Tension, Dispersion, and Emulsion processes.
