B-206 Aliphatic Polyurethane Acrylate Oligomer

B-206 is a dual-functional PUA resin with excellent weather resistance and flexibility. It can be used for UV plastic spraying to adjust the hardness and flexibility of the formula and balance the formula's resistance to boiling, salt spray, high and low temperatures, and hot and cold cycles. It is used in UV printing varnishes and inks and can be used as the main PUA in the formula to bring comprehensive solvent resistance, flexibility, yellowing resistance and faster UV curing activity.
