Kyoritsu Adhesives
Kyoritsu Chemical & Co., Ltd. manufactures adhesives used in optical communication devices.
Kyoritsu Chemical & Co., Ltd. manufactures adhesives that are used in a variety of optical devices for highly accurate component attachment. The adhesives have desirable attributes, such as high glass transition temperature and low moisture absorption, making it ideal for fixing components that require high accuracy. The adhesives can be used, for example, to fix fibers in V-groove arrays, or Fiber Bragg Gratings to substrate/fibers.
Hitachi High Technologies America is Kyoritsu Chemical & Co., Ltd.'s sales and marketing representative for North America.
Advantages:
