It is a light stabilizer belonging to the benzotriazole class of UVAs, especially suited for polyolefins and cold cured polyesters. RIASORBUV-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 molding processes.
