Product Properties

1.UV-326 is especially suited for polyolefins and cold cured polyesters. UV-326 has a wide range of indirect food approvalsin polyolefins. lt has a low volatility at high temperatures and high resistance to thermal degradation and can thereforebe used without significant loss or decomposition in the polyolefin compounding and molding processes.
2.In the use forthe UV protection of polyester resins, UV-326 does not form colored complexes with the metallic salts used for the curingprocess of these resins.
