EBECRYL® 3730-TP25

1 of 314 products in this brand
EBECRYL® 3730-TP25 is the modified diacrylate ester of a bisphenol A-based epoxy resin, diluted with 25% by weight of the reactive diluent tripropylene glycol diacrylate (TPGDA) (1). This formulation is specifically designed for use in ultraviolet light (UV) or electron beam (EB) curable formulations. Characterized by its light color, high UV/EB reactivity, and effective wetting of pigments, matting agents, and substrates, EBECRYL 3730-TP25 offers enhanced performance compared to unmodified epoxy acrylates. Cured films based on this formulation typically exhibit high gloss, hardness, and good chemical resistance. End uses for EBECRYL® 3730-TP25 include radiation-curable coatings and varnishes, making it suitable for a range of applications such as automotive OEM coatings, wood coatings and finishes, other packaging coatings, and overprint varnishes.
