Product Details
Characterization |
Light Stabilizer 770 is a low molecular weight hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It provides excellent light stability for thick sections but can also be used for articles with a high surface area such as films and tapes. |
Applications |
Light Stabilizer 770? is recommended to be used in polypropylene, impact modified PP (TPO), EPDM, polystyrene, impact polystyrene, ABS, SAN, ASA, polyurethanes, and is also effective in polyamides and polyacetals. |
Guidelines for use |
The recommended concentrations range between 0.1 % and 1.0 %, depending on the substrate, processing conditions and application. The optimum level is substrate and application specific. Extensive performance data of Light Stabilizer 770 in various substrates and for various applications is available upon request. |
Handling |
In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Avoid continuous or repetitive breathing of dust. Use only with adequate ventilation. Avoid contact with eyes. Avoid release to the environment. Avoid dust formation and ignition sources. |
General Description |
Bis(2,2,6,6-tetramethyl-4-piperidyl) (T770) sebacate is a low molecular weight ultra violet (UV) hindered amine light stabilizer (HALS) made up of nitroxyl radicals. It acts as a heat controller that can react with phenolic antioxidants incorporated in polymers. |
