| Application & Usage | UV-326 is especially suited for polyolefins, cold cured polyesters and wood lacquers. UV 326 has a wide range of indirect food approvals in polyolefins. It has a low volatility at high temperatures and high resistance to thermal degradation and can therefore be used without significant loss or decomposition in the polyolefin compounding and moulding process. |
