LAM-1425-XP10: Low Refractive Index Optical Lamination Adhesive
LAM-1425-XP10 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-XP10 is distinguished by its low modulus which enables improved endurance under thermal cycling and thermal shock.

Storage
- Avoid unnecessary exposure to ambient light and moisture.
- Long term storage should be at ambient conditions of 10-30ºC.
- The coating is supplied in bottles and in syringes.
- The shelf life is 6 months.
Application
Curing can be achieved by any source of UV at 300-400nm. Typically, a dose of 2000-4000 mJ/cm2 is necessary.
There is no need for inert atmosphere when curing between two layers or in a mold.
Keep the bottle closed in all times when not in use. The material is sensitive to light and moisture.
