Photo-stabilizer BW-10LD - Reference Information

EPA chemical substance information information provided by: ofmpeb.epa.gov (external link)
light stabilizer The light stabilizer is a substance that improves the light stability of a polymer material. It can shield ultraviolet light, reduce the transmission of ultraviolet light; Or can strongly absorb high-energy ultraviolet light (wavelength 290~400 μm) for energy conversion, in the form of thermal energy or harmless longer wavelength light to emit energy; Or can quickly be excited by the excited state of the polymer UV quenching, back to a stable ground state; or can be very effective to capture the UV-induced polymer generated by the free radical, so as to achieve the protection of polymer materials, so that it is free from UV damage. In addition to protecting the polymer material, the light stabilizer can also be used to protect the package from ultraviolet rays and as an essential component in the filter.
The light stabilizer almost does not absorb the ultraviolet light which can cause the aging of the plastic, and the purpose of preventing the aging of the plastic is achieved. The mechanism of action of the light stabilizer is that it can effectively trap the free radicals generated by the plastic itself caused by ultraviolet light, thus preventing the occurrence of the chain reaction leading to the aging of the plastic. Such light stabilizers are also referred to as free radical trapping agents. Hindered amine is still the most important light stabilizer (free radical trapping agent) at present, and its stabilization mechanism is shown in the figure below:
that is, hindered amine generates N-O free radical stable to light under the action of O2, it is combined with the free radical R generated by the plastic itself under the action of ultraviolet light, thereby preventing the aging of the plastic.
at present, the commonly used light stabilizers can be roughly divided into five categories according to their mechanism of action, namely: Ultraviolet absorbers, such as salicylic acid esters; "precursor" Ultraviolet absorbers (Itself does not absorb the role of ultraviolet light, light irradiation, molecular rearrangement, UV absorber), such as benzoic acid esters; "extinction effect agent", mainly nickel chelate class; Free radical capture agent, mainly hindered amines; Light shielding agent, mainly including carbon black, titanium dioxide and zinc oxide and other pigments.
raw and auxiliary materials for architectural coatings exterior wall coatings that are directly exposed to UV radiation and moisture in the air and other factors, exposure to photoaging may result in a decrease in physical properties. The addition of light stabilizer to the coating can delay or inhibit the process of light aging of the coating, improve the weather resistance of the coating film, and prolong the effective life of the coating, which is very important for the exterior wall architectural coatings.
There are many kinds of binders for architectural coatings, and the degree of light aging under ultraviolet irradiation varies with different resins, such as Acrylate Resins and polyurethane, which have good light aging resistance, and some varieties, such as chlorinated rubber, polyvinyl acetate, polyvinyl chloride, vinyl chloride is poor, when used as exterior wall paint should avoid the use of such resins.
The commonly used light stabilizers can be divided into three categories: ultraviolet absorber, ultraviolet light quencher and ultraviolet light screening agent.
The ultraviolet absorber can selectively and strongly absorb ultraviolet rays, and can convert the absorbed energy into thermal energy or dissipate secondary radiation energy (fluorescence), but does not chemically change by absorbing ultraviolet rays. In this way, the material can be prevented from being damaged by ultraviolet rays, and such varieties include O-hydroxybenzophenones, glycinates, O-hydroxybenzotriazoles, and the like.
The role of UV quenchers is not to absorb UV light, but to transfer the energy of the excited molecules in the polymer excited by UV radiation before the photochemical reaction occurs, the molecule is then returned to a stable ground state, thus avoiding photoaging of the polymer. A commonly used quencher is an organic nickel compound.
light-shielding agents are substances capable of absorbing, scattering and reflecting ultraviolet rays before UV radiation harms polymers, and various pigments commonly used in coatings, such as zinc oxide, iron oxide, chromium oxide, carbon black, pigments of the phthalocyanine series and the like can all play this role.
Application hindered amine light stabilizer, can be used for polyethylene, polypropylene, polyurethane, polyamide and polyester elastomers
light stabilizer 622 is a high molecular weight light stabilizer with multiple functional groups. It can be used for low density polyethylene film, polypropylene tape, EVA film, ABS, pp fiber PE, polyoxymethylene, polyamide, polyurethane, polyvinyl chloride, PVC blend material, polystyrene, rubber and viscose, it can be used with UV sorbents because of its special structure and large molecular weight (3000). It can also be used in film and fiber. It can also be used as antioxidant and polymer heat stabilizer, and the dosage of agricultural film is 0.2%
