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 the functional raw materials. Our landmark achievements include the evolotion of flat panel, semi-conductor, and Nano-technologies.
 
In the mass production of functional raw materials the wet-process coating has been in heavy use. From the start to finish of coating process flow it is essential to control and properly identify interfacial troubles that occur in and between raw materials.

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