Présentation du produit & avantages clés
HALS 144 (bis(1,2,2,6,6-pentamethyl-4-piperidyl) [[3,5-bis(1,1-diméthyléthyl)-4-hydroxyphényle]méthyle]butylmalonate) combines a hindered amine and a hindered phenol, so it protects against both UV and thermal oxidation. As a solid it suits powder coatings and is also used in automotive coatings and selected plastics.
Powder coatings
Solid form suits powder coating formulations.
Heat and UV
Protects during bake and in outdoor service.

Sélection & comparaison
Selecting a Light Stabilizer
| Votre exigence | Ce qui fonctionne habituellement |
|---|---|
| Thick PP and PE parts | Low-MW HALS (770) for fast migration to the surface |
| Films minces, tapes and fibers | Polymeric HALS (944, 622) for low volatility and extraction resistance |
| Agricultural film exposed to pesticides | Polymeric HALS with good resistance to acidic residues; ask about the specific chemicals |
| Automotive and industrial coatings | Liquid HALS (292) with a UV absorber |
| Acid-catalyzed coatings | Non-basic NOR-type HALS (123) |
| Long outdoor life | HALS plus UV absorber, often a blend of a low-MW and a polymeric HALS |

Définissez les niveaux dans votre propre essai. The right level depends on part thickness, pigments, charges, agrochemical exposure and target service life. Combining a HALS with a UV absorber is usual for outdoor use.
Emballage & stockage
Emballage
25 kg net bags or cartons with a PE inner liner. Palletized.
Stockage
Keep sealed in a cool, sec, ventilated place away from heat and direct sun. See the SDS for full handling details.
Délai de mise en œuvre & terms
Regular grades are usually in stock. For large volumes, lead time is confirmed in the quotation. We quote FOB and CIF.
Du premier e-mail à la fourniture approuvée
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), conditionnement, 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.

Voir le produit →Stabilisateur de lumière 144 FAQ
Why choose 144 for powder coatings?
It is a solid, so it suits powder formulations, and its built-in phenolic adds heat stability during baking.
How much SUNLIGHT® 144 dois-je ajouter?
Le niveau dépend de votre polymère, épaisseur de la pièce, autres additifs et conditions d'essai, alors mets-le dans ton propre essai. La TDS est disponible sur demande.
Does it replace a separate antioxidant?
It contributes antioxidant action, but some systems still use a separate antioxidant. Send your formulation for advice.
Puis-je obtenir un échantillon avant de commander?
Oui. 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.
Que se passe-t-il si un COA ne correspond pas à nos spécifications convenues ??
Send us the agreed specification and the COA showing the difference (parameter, unité et méthode de test). 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.
