UV Stabilizer 622 is an oligomeric hindered amine light stabilizer (HALS) designed to provide long-term UV protection and thermal stability in plastics and coatings. Its high molecular weight ensures low volatility, minimal migration, and excellent extraction resistance, making it particularly suitable for polyolefins, elastomers, and engineering plastics. It is effective in both pigmented and non-pigmented systems and works well with carbon black formulations. The molecular formula (C₁₇H₃₁NO₄)ₙ corresponds to the repeating unit of UV Stabilizer 622, also known as Light Stabilizer 622. This polymeric hindered amine light stabilizer (HALS) is characterized by its high molecular weight, ranging between 3,100 and 4,000 g/mol. Its oligomeric structure ensures low volatility and minimal migration, making it effective in protecting polymers from UV-induced degradation.

Chemical Properties & Specifications
Avoid dust formation and inhalation of vapors, mist, or gas. Prevent contact with skin and eyes. Use personal protective equipment (PPE), including gloves and protective eyewear. Ensure adequate ventilation in the workspace. Keep away from sources of ignition, as the product can form explosive dust/air mixtures.
Use dry chemical, carbon dioxide, alcohol-resistant foam, or water fog to extinguish fires. Wear self-contained breathing apparatus and chemical-protective clothing during firefighting. Be aware of the potential for explosive dust/air mixtures.
Prevent further spillage if safe to do so. Do not allow the chemical to enter drains or waterways. Dispose of in accordance with local environmental regulations.
