Storage
- Avoid unnecessary exposure to ambient light and moisture.
- Long-term storage should be at ambient conditions of 10-25ºC.
- Do not refrigerate.
- The coating is supplied in glass bottles. Keep the container closed to avoid moisture penetration.
- The shelf life is 12 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 50oC.
Keep the bottle closed at all times when not in use. The material is sensitive to light.
