Omnirad BDK

Omnirad BDK is a highly efficient type I photoinitiator utilized to initiate radical polymerization of unsaturated oligomers, particularly acrylates, upon exposure to UV light. It's commonly employed in UV curable coating, ink, and adhesive formulations for various substrates such as paper, wood, metal, and plastics. This photoinitiator is compatible with both mono and multi-functional monomers as reactive diluents.
