LAM-1425-XP1: Low Refractive Index Optical Lamination Adhesive

LAM-1425-XP1 is a PFAS-Free low refractive index UV curable adhesive designed for bonding flat surfaces such as glass sheets and plastic films. Typical applications are bonding (or lamination) of waveguides in AR displays, smartphone displays or attaching optical touchscreens to an LCD module. It has good adhesion to glass, metals and various plastics (such as PC, PET, PMMA). LAM-1425-XP1 is distinguished by its low modulus which enables improved endurance under thermal cycling and thermal shock.

Storage

  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 adhesive is supplied in bottles or syringes. Keep the container closed to avoid moisture penetration.
  5. The shelf life is 6 months.

Application

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

For ease of application, the adhesive may be preheated up to 60oC.

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