Lucent Gel

Lucent Gel is a pliable silicone based solid optically clear adhesive (SOCA). Produced under strict environmental controls, Lucent Gel is transparent, UV-resistant, and can withstand a wide range of temperatures and humidity. Lucent Gel can be produced thick to fill imperfections and increase adhesion.

Lucent Gel has the following characteristics:

  • Very ductile and pliable
  • Suitable for uneven surfaces
  • Fills gaps
  • Reworkable
  • High adhesion
  • Resists extreme temperatures
  • Clarity and brightness increased 10% compared to Air bonding
  • Better optical characteristics compared to liquid bonding
  • Will not yellow

The Lucent Gel Advantage

Solid silicone based adhesives possess a number of advantages. Comparisons of solid and liquid optically clear adhesives (LOCA) and silicone and acrylic-based adhesives are as follows:

  • Evenly thickness, best optical effected
  • High adhesion gel, able to use on low Dyne number substrate surface
  • Easy lamination process, shorten process time with high yield rate
  • Rework
