LM-142-NI : Optical Coating / Adhesive
LM-142-NI is a low modulus (highly flexible) low refractive index UV curable coating/adhesive which does not require inert atmosphere during the curing process. The material was optimized for curing by both UV LED and UV Mercury lamps. The main application is re-coating.

- Avoid unnecessary exposure to ambient light and moisture.
- Long term storage should be at ambient conditions of 10-30ºC.
- 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.
Keep the bottle closed in all times when not in use. The material is sensitive to light.
