LAM-134: Low Refractive Index Optical Lamination Adhesive

LAM-134 is a low refractive index UV curable lamination adhesive. It has excellent adhesion to polycarbonate (PC), PET, PMMA, and glass. A typical application is a lamination of PC or other plastic films, for example in display screens for smartphones, AR glasses, and VR headsets.



Refractive index at 589 nm 1.346
Refractive index at 950 nm 1.340
Density 1.60
Viscosity 3500
T- Peel Force, PC/PC 360
Shelf life 12 months



  1. Avoid unnecessary exposure to ambient light and moisture.
  2. Long-term storage should be at ambient conditions of 10-30ºC.
  3. Do not refrigerate.
  4. The coating is supplied in glass bottles. Keep the container closed to avoid moisture penetration.
  5. The shelf life is 12 months.



Curing can be achieved by any source of UV at 300-400nm. Typically, a dose of 1000-2000 mJ/cm2 is necessary.

For ease of application, the adhesive may be used preheated up to 80oC.

Keep the bottle closed at all times when not in use. The material is sensitive to light.
