Polyester acrylate
B-574
Product features:
B-574 is a high-functional polyester acrylate that is benzene-free, odorless, low-viscosity, and features rapid curing. It exhibits excellent compatibility with other resins and demonstrates outstanding wetting and dispersing properties for pigments. The VOC content of B-574 meets the standards for cigarette packaging. Its viscosity is only 5 to 8 times that of TMPTA, yet its cured hardness is comparable to DPHA. Moreover, its required exposure energy is even lower than that of DPHA—UV energy as low as 100 mJ/cm² can fully cure a 50-micron-thick film in a single pass.
