High Refractive Index Optical Adhesives

Viscosity 70->20,000 mPas; Shear Bond Strength > 69->200 kgf/cm²; Bending Adhesion Strength 9-25 kgf/cm²; UV Curing Conditions 10-100 mW/cm², 5, 10 min; Colour Light Yellow, Colourless, White; Tg +42-+219 °C NTT-AT’s series of adhesives for fiber array assemblies feature high moisture resistance and excellent workability for v-groove fixing or optical fiber fixing. Fiber arrays are used for the input and output of optical waveguide devices. NTT-AT’s AT3925M, AT9390, AT9968, AT3727E and AT3728E epoxy-based optical adhesives are used for fixing the v-grooves and have realized price reductions while enhancing moisture resistance compared to conventional products. These adhesives can be polished after assembly. NTT-AT’s AT9575M (epoxy) and AT8105 (acrylate) adhesives for optical fiber fixing have gained popularity for their good workability as non-fluid adhesives. NTT-AT has executed durability tests that have shown no peeling of a fiber array after 2,000 hours at +85 °C and 85% of humidity. With viscosities that are appropriate for the usage location, the adhesives for fiber array assemblies are easy to use. While the adhesives for fixing v-grooves show fluidity, the optical fiber fixing adhesives’ consistency is that of a paste, suitable for protecting the fiber.
