PHOTOMER® 4157 is a medium molecular weight analogue of ethoxylated TMPTA, offering good hydrophilicity due to its increased ethoxylate content. It serves as an excellent base for developing water-dispersible UV/EB curable inks and coatings. PHOTOMER® 4157 is used in UV curable formulations for various substrates like paper, wood, metal, plastics, and glass. It exhibits excellent cross-linking reactivity, providing hardness without brittleness, making it ideal for industrial applications requiring water dispersibility, such as screen printing and lithographic inks.
