52829-07-9 Usage
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
Different sources of media describe the Applications of 52829-07-9 differently. You can refer to the following data:
1. 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.
2. Light Stabilizer 770 is a low molecular weight hindered amine light stabilizer that provides
excellent light stability for thick sections and films in the recommended
substrates. 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.
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.
Chemical Properties
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
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 52829-07-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,2 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 52829-07:
(7*5)+(6*2)+(5*8)+(4*2)+(3*9)+(2*0)+(1*7)=129
129 % 10 = 9
So 52829-07-9 is a valid CAS Registry Number.
