The product is supplied pre-filtered to below 1 micron particles.
- Avoid unnecessary exposure to ambient light.
- The shelf life is 12 months in sealed bottles.
Curing can be achieved by any source of UV at 300-400nm under inert conditions. A dose of 500-1000 mJ/cm2 is necessary. Although inert atmosphere is preferred, curing in air is also suitable.
Keep the bottle closed in all times when not in use. The material is sensitive to moisture. Absorption of moisture may cause haze.
