Photo initiator 369   is a highly efficient UV curing agent which is used to

initiate the photopolymerisation of chemically prepolymers - e.g.

acrylates - in combination with mono- or multifunctional monomers.

Photo initiator 369  is especially suitable for pigmented UV curable systems,

photoresists and printing plates.
