Evaluation of three UV absorbers

February 14, 2019
blog

In this article we evaluate three different UV absorbers. They have advantages and associated characteristics. First an introduction of the UV absorbers:

Omnistab UV 1577 TF is a toluene free hydroxyphenyl triazine UV absorber. Exhibits very low volatility and good compatibility with a variety of polymers. It allows polycarbonates and polyesters to achieve a higher resistance to weathering than conventional benzotriazole UV absorbers.

Omnistab UV 3030 is a very low volatile ultraviolet light absorber (UVA) of the cyanoacrylate class, imparting excellent light stability to engineering polymers. Features maximal thermal stability and no inherent color. It can be used to stabilize highly transparent polymers with high extrusion temperatures.

Omnistab UV 3638 offers very strong and broad UV absorption with no color contribution. Provides low volatilty. Imparts high UV screening efficiency.

Differences and recommendations

Omnistab UV 1577 TF is a hydroxy-benzotriazine UV-absorber. In addition, it is active in both UV-B and UV-A regions. It shows very good results in PET photo-stabilization. The UV 1577 TF is used for PC, but less recommended than UV 3030 as sometimes blooming and build up phenomena were observed during production of PC transparent sheets. Can be used for photo-stabilization of ABS plastics and other engineered plastics as well. Above all, it is more effective than hydroxy-triazole UV absorbers, like Omnistab UV 329. Can be recommended for 20 year stability of PET sheets. Less effective than Omnistab UV 1600 (this product is currently in development). For instance, requires higher concentration to get the same photo-stabilizing effect.

Omnistab UV 3030 is a Cyano-acrylate type UV absorbers active mostly in UV-B region. It is very effective for stabilization of polycarbonate (PC). its stable at processing temperatures of PC (some 300C) without blooming and build up phenomenon on tooling equipment. Moreover, it can be recommended for 20 years lasting of PC in outdoor conditions together with Omnistab UV 1600.

Omnistab UV 3638 is a Benzoxazine type UV-absorber with strong absorption in UV-A region and less absorption in UV-B region. It is effective in photo-stabilization of PET. However, in lesser extent than UV 1577. It possesses high thermal stability. Can be used in different Engineered polymers. In conclusion, we recommend the Omnistab UV 3638 for less durable products. For example, 10 years lasting).
