UV curable resin with built-in photoinitiator (PIUVO)

UV curable resin with built-in photoinitiator (PIUVO)

By incorporating the photopolymerization initiator into the resin frame by chemical bonding, UV curing can be performed without adding a photopolymerization initiator afresh. Bleed-out after UV curing can be suppressed.

UV-H-4000, 5630, 5630TF, 6200, 6200TF, 7000

A UV curable resin where a photoinitiator is incorporated into the frame.
TF: Tin-free compatible product

Characteristics

  • It can be UV cured without adding a photoinitiator.
  • It can be used as a hard coating agent.
