With the refractive index of 1.5 in normal resins, the problem of a high reflection loss arose in cases of adhesion with high refractive index glass and crystal materials.

Recently, resins with refractive indices of 1.7 or more, 1.4 or less and high refractive index, low refractive index resins, which are also excellent in transparency in visible light domains have been developed.? As well as being adhesives for high refractive index glass and crystal materials, since they excel in transparency while also having a high refractive index, it is expected that they can be used as a coating agent for displays and similar products. Moreover, to match the particular working environment of our customers, we have prepared both ultraviolet curing and heat curing types.

Applications

• High and Low Refractive Index Coating Agents
• Adhesives for High and Low Refractive Index Crystal Materials
• Adhesives for High and Low Refractive Index Glass (for camera lenses, eyeglass lenses, etc.)
• Higher Efficiency Optical Input and Output Power
• Efficient Conversion of Light Energy
