Tinuvin® 770 DF

Technical Datasheet | Supplied by BASF
Tinuvin® 770 DF by BASF is bis(2,2,6,6,-tetramethyl-4-piperidyl)sebaceate. It 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. Tinuvin® 770 DF 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. The recommended concentrations range between 0.1-1.0%, depending on the substrate, processing conditions and application.

Hansen Solubility Parameters

[16.6, 2.6, 2.2]
?
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Tinuvin® 770 DF. A practical determination of these HSP values would provide higher certainty. Learn More.
