Resin product lineup

Low moisture permeable adhesive, Photolec E

This adhesive is cured with UV, and can be used to bond polarizing plates quickly at low temperatures.

1. Characteristics

  1. We have two lineups for the Photolec E: one is cured quickly after UV irradiation, and the other one is cured with low heat after UV irradiation
  2. Low Outgas, Moisture-proof

2. Temporary curing procees

Dispense→UV Curing→Bonding→Heat Curing

  • UV delay-curing proces

3. Applications


This type is best for sealing materials which are subject to heat, for polarizing parts, and for plastic plates.

2Low moisture permeability

Moisture-proof sealant for OLED Display
【Structure of OLED display (top emission type)】
  • Moisture-proof sealant for OLED Display
  1. This product releases minimal gas generated during curing proccess (UV/heat)
  2. Semiconductor (MEMS, CCD) sealing

Low Outgas

  • UV delay-curing clear adhesive with high viscosity (Photolec E)
    Strong and highly accurate adhesion can be achieved
    ※ With Micropearl SP/GS
  1. Bonding for plastic substrates
  2. Bonding for optical components
  3. Hard disks, surrounding sealants (low moisture permeability), internal adhesive (low outgas)
  4. Semiconductor(MEMS,CCD camera module)
