Adhesives for Optical Waveguides

Refractive Index 1.603-1.720; Viscosity 9-7,000 mPas; Transmittance 72%-96%; Hardness 67-83 Shore D; Shear Bond Strength 35->280 kgf/cm²; UV Curing Conditions 10, 100 mW/cm², 5, 10 min; Tg +63-+113 °C With a typical refractive index of 1.5 in conventional optical adhesives, the problem of a high reflection loss arose in cases of adhesion with high refractive index glass and crystal materials. Utilizing its refractive index control technology and optical loss reduction technology, NTT-AT has developed optical adhesives with a high refractive index adjustable to 1.6 or more. By adding high refractive index fillers, NTT-AT is even able to manufacture resins with a refractive index of 1.9. These resins are aimed at usage in the fields of optical recording, display technology, optical energy uses, etc. In addition to this series, NTT-AT also provides high refractive index resins for nanoimprint applications. NTT’s high refractive index resins are excellent in transparency in visible light domains, with haze values of 1 or less, so it is expected that they are used as a coating agent for displays and similar products. Within this series, you find acrylate-based adhesives (#18165 and #6205) as well as epoxy adhesives (E3754 and E7200). To match the particular working environment of our customers, NTT-AT provides both ultraviolet (UV) and heat curing types. NTT-AT provides refractive index customized resins to meet each customer's needs. It is possible to respond to several kinds of requests such as with/without solvent or adjusting the viscosity.
