White solid | [Uses]
T770 can be used as a hindered amine UV stabilizer in plastic materials. It can be used in the manufacturing and packaging of pharmaceutical products. Titanium oxide(TiO2)/T770 may be used in amine induced light stabilizers in the synthesis of recyclable water-based polyurethane with poly(oxytetramethylene)glycol (PTMG). | [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. | [Flammability and Explosibility]

| Questions And Answer | Back Directory | [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.
| [Applications]
Light Stabilizer 770 (Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate) is a low molecular weight hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. The benefit of using Light Stabilizer 770 is the high light-stabilizing performance, particularly in PP thick sections to protect the surface. It has broad compatibility and can be easily dispersed. Compared to UV absorbers, the effectiveness of HALS, like Light Stabilizer 770, is not dependent on the polymer’s thickness. For this reason, the use of Light Stabilizer 770 also provides good light stability in articles with higher specific surface, e. g., films and tapes.
| [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.
| [Physical properties]
 | [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.
