Product Details

Optically-Clear Resin

Our adhesive lineup includes grades appropriate for use with polarizers. They can be customized to have low water vapor transmission rate and/or dielectric constant, and UV peel-off adhesives for semiconductor manufacturing.

Typical adhesive types

For polarizers (& retarders)

Our products support various polarizer applications.

  • Countermeasure for light irregularity
  • Long-lasting
  • Acid-free
Various refractive index

We offer optical adhesives in both high and low refractive index types.

  • Modifying the refractive index allows you to suppress optical loss that occurs at the interface with the adherend, thus contributing to better optical design.
  • High refractive index type: Refractive index 1.59
  • Low refractive index type: Refractive index 1.37
High Moisture Barrier
  • Low water vapor transmission
  • Low dielectric constant
UV peel-off type (for semiconductor manufacturing)

The UV peel-off adhesive for semiconductor processes decreases adhesion at a low amount of UV irradiation (400 mJ).

  • Before UV irradiation: High adhesion
  • After UV irradiation: Zero adhesion
Bio-based adhesive

This acrylic adhesive is made of biomass materials. ZACROS can freely adjust adhesion strength for re-peeling, bonding and fixing applications. This adhesive achieves a haze of 1% or less and can also be used for optical applications. Some products with a high concentration of 78% biobased content, or certified with the Biomass Mark*, are also available.

*This mark can be only used by products certified by the Japan Organics Recycling Association (JORA).

  • Wide range of adhesive strengths
  • High transparency
  • High content of bio-based material
