Applications:
TPO is an effective photoinitiator for UV-curable based coatings,adhesives, inks and printing plates. It is typically consumed in unsaturated polyester acrylatebased systems in concentrations ranging from 1% to 4% by weight. It offers the advantage of good shelf stability,and fast and thoroughcure of coatings. It is compatible with unsaturated polyesters, acrylate monomersand oligomers for use in UV-curable systems.
