Performance Materials (Functional Materials)

Our electronic material binder is all about high functionality of acrylic polymer


PHORET is a functional acrylic polymer that was developed based on our original synthesis technology to fit transparency need, attach functionality and composition with other materials.
In addition to our existing products, we also provide customized acrylic polymer products in response to customers' requests by working on designing, development and production of materials and manufacturing systems.

Functions provided by PHORET

Applications of PHORET

PHORET has a wide range of applications for coating, resist blending, conductive paste, and electronic and optical materials. In particular, the ZAH line of products provides excellent developability of an alkali-soluble material, allowing the optimum combination of molecular weight and acid value to fit a resist binder for photolithography. We also make proposals for applications as a functional coating binder for electronic and other advanced materials by keeping the edge of primary transparency and adhesion to materials, high refractive index and yellowing resistance.
