1. Highest output from direct excitation of the acrylate double bond:

• Improvement of chemical and temperature resistance
• Better mechanical properties
• Better light and weathering stabilitiy.
• Crosslinking of fixed systems (UV water-based coatings) and post-crosslinking of polymers with residual double bonds efficient possible
• Crosslinking density higher than with EBH (Electron Beam Hardening)
• no negative influence to the substrate as EB on Paper, PVC, etc

2.  No or very low (<0.5%) concentrations of photoinitiators required, resulting in:

• Significant reduction of migration and VOC (Volatile Organic Compounds) emission
• No “UV odor”
• Limit values for migration from food packaging can be adhered to.
• Migration and VOC emission similar to EBH at doses of 30 to 40 kGy.

3. Oxygen sensitivity of UV curing greatly reduced:

• Operation of UV systems up to 1000 ppm residual oxygen possible.
• Nitrogen production through PSA (Pressure Swing Adsorption) as an alternative to vaporization possible.
