Efficient at low loading
Regenerative mechanism gives long protection at 0.1–0.5%.
HALS 770 Light Stabilizer Supplier
Sunlight® 770 is a low-molecular-weight hindered amine light stabilizer (HALS). It protects thick polyolefin and styrenic parts against UV degradation, often together with a UV absorber or a polymeric HALS.
CAS 52829-07-9 · Monomeric HALS
Visão geral do produto
HALS 770 (bis(2,2,6,6-tetrametil-4-piperidil) sebacatar) traps the free radicals formed by UV exposure and regenerates, so it protects for a long time at low loading. Its low molecular weight (480.7) lets it move to the part surface quickly, which suits thick parts; for thin film and fiber it is often blended with a polymeric HALS such as 944.
Typical specification. Every shipment is supplied with a batch COA; the limits that apply to your order are confirmed in the quotation and contract.
Key Benefits
Thick parts
Fast migration to the surface suits thick moldings.
Blends well
Often combined with 944 or a UV absorber for longer life.

Technical & Buying Information
Estabilizador de luz 770 Guia do comprador
Define the exposure
Note the climate, the expected service life and your weathering test (xenon or QUV hours, retained elongation, gloss or ΔE). For agricultural film, list the pesticides and fumigants the film will meet.
Pick molecular weight for the part
Low-MW HALS move to the surface quickly and suit thick parts; polymeric HALS resist loss from thin films and fibers. Many outdoor packages blend both.
Check interactions
HALS are basic and can interact with acidic additives, halogenated flame retardants, some pigments and sulfur-containing antioxidants. Send your full formulation so we can flag conflicts before the trial.
Lock in supply terms
Agree physical form (powder or granule), embalagem, monthly volume and documents up front. A matching CAS number alone does not qualify a new source; run your weathering test and keep the approved lot COA as the reference.

770 ou 944?
770 is best for thick parts; 944 (polymeric) is better for thin film and fiber. Many outdoor packages blend both.
What dosage is typical?
0.1–0.5% depending on thickness and exposure.
Can I use 770 in agricultural film?
Low-MW HALS can be lost from thin film; polymeric HALS such as 944 ou 622 are usually preferred there.
Can I get a sample before ordering?
Sim. Tell us the polymer, the test you plan to run and the quantity you need. Samples ship with a COA so you can compare the lot against your current material.
What if a COA does not match our agreed specification?
Send us the agreed specification and the COA showing the difference (parameter, unit and test method). We check it with the production batch record before you accept the material, and replace or re-test where the lot is out of specification.
