Aliphatic polyurethane acrylate
B-206
Product features:
B-206 is a bifunctional PUA resin with excellent weather resistance and flexibility. It is used in UV plastic coatings and allows adjustment of the formulation’s hardness and flexibility, while also balancing its resistance to boiling water, salt spray, high and low temperatures, and thermal cycling performance. When used in UV printing varnishes and inks, B-206 can serve as the primary PUA component in the formulation, providing comprehensive resistance to solvents, flexibility, resistance to yellowing, and faster UV curing activity.
