2. Features:RU-2085B is a bifunctional PUA resin that does not contain organotin and has excellent weather resistance, flexibility, high gloss, and high fullness. Used for UV plastic spraying, it can adjust the hardness and flexibility of the formula, balance the formula's resistance to boiling, salt spray, high and low temperature, and cold and hot cycling performance; Used for UV printing varnish and ink, it can serve as the main PUA in formulations, bringing comprehensive solvent resistance, flexibility, yellowing resistance, and fast UV curing activity.
