Adhesives

  • High Refractive Index Adhesives LPK-series
    LPK-series are high refractive index adhesives. Their refractive index (1.60~1.66), Abbe’s number (high/low) and viscosity (high/low) can be customized.

  • High Refractive Index / High UV Resistance / Rapid Curing Adhesive LPK-2000
    LPK-2000 is a high refractive index adhesive and free from inhibition of oxygen. It is suitable for applications with high light exposure and curing processes under atmospheric condition.

  • Medium Refractive Index / Heat Resistance Adhesive LZD-2020
    LZD-2020 is a medium refractive index adhesive. It is suitable for adhesion of both poor-adherent inorganic and plastic materials. It shows high adhesion after an exposure to high temperature.
