High refractive index resin

We offer UV-curable high refractive index resins that have excellent transparency in the visible light range.
Based on the advanced technology we have cultivated in optical adhesives, we can customize products to meet our customers' needs.

Adhesive for precision fixing

Adhesive fixation on the order of submicrons is possible because there is very little change in fixing position due to curing or temperature changes.
*Low cure shrinkage (less than 2%)
*Low coefficient of thermal expansion (40 ppm/℃ or less)

AT9290F becomes transparent after curing
High reliability that withstands heat cycle tests (-40 to 85°C)
High heat resistance (260°C) that withstands solder reflow processing

Optical adhesive

Adhesive technology used in optical communication is one of our main technologies. In order to put low-cost and highly reliable optical components into practical use, adhesives that can be easily adhered and have excellent durability are required. The requirements differ depending on which part of the optical component it is used in. We develop and commercialize adhesives and resins that meet customer needs, such as refractive index matching, precision fixing, heat resistance and high elasticity, and low moisture permeability.
