The effectiveness of UV-622 surpasses significantly that of UV absorbers, particularly in pigmented systems. Combinations of UV-622 with UV absorbers, e.g., UV range or other HALS range in many cases result in synergistic effects. Typical examples are UV-783.

Furthermore UV- 622 is effective as antioxidant and contributes significantly to the long-term heat stability of polyolefins and tackifier resins.
