Darocur TPO 2,4,6-Trimethylbenzoyl-diphenyl-phosphine oxide Ciba Photoinitiator Acrylic/Acrylate Resins Polyester Inks >> UV / Radiation-curable Coatings >> UV / Radiation Curing Printing Inks & Varnishes Wood & Furniture Coatings Plastic coating Metal Other industry >> Paper coatings Darocur TPO Photoinitiator DAROCUR TPO is a highly efficient curing agent which is used to initiate radical photopolymerisation of unsaturated resins such as those based on a prepolymer such as acrylates in combination with mono- or multifunctional monomers as reactive thinners. DAROCUR TPO may be used after adequate testing in UV curable formulations for clear and for pigmented coatings on wood, metal, plastic, paper and optical fibers as well as for printing inks and adhesives. DAROCUR TPO offers good solubility in common UV reactive systems, e.g. systems based on acrylates or unsaturated polyesters. It can be used as the sole photoinitiator or in combinations with other photoinitiators, such as alpha-hydroxy ketones. Recommended concentration: 1 - 5 % DAROCUR TPO Highly efficient curing agent.
