Uses

UV 326 is especially suitable for polyolefin and cold cured polyesters. 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 polyolefin compounding and molding processes. In the use for the UV protection of polyester, UV 326 does not form colored complexes with the metallic salts used for the curing process of these resin.

It is also used for photosensitive materials and coatings and so on.
