Technical Datasheet | Supplied by allnex
DPHA by allnex is a multifunctional reactive diluent that polymerizes when exposed to sources of free radicals. It is particularly useful in ultraviolet light (UV) and electron beam (EB) curable coatings and inks where improved cure response, hardness and scratch/abrasion resistance are desired. It offers high cross-link density and good chemical resistance. It is characterized by very low vapor pressure, high acrylate- and hydroxyl- functionality. DPHA is recommended for scratch resistant coatings for plastics, lithographic and screen inks.
