In the world of material science, protecting polymers and coatings from the relentless assault of ultraviolet (UV) radiation is paramount for ensuring longevity and preserving aesthetic and functional integrity. NINGBO INNO PHARMCHEM CO.,LTD. offers a superior solution in this regard with its advanced product, Ultraviolet Absorber UV-292.

UV-292 is a highly effective liquid hindered amine light stabilizer (HALS), recognized by its CAS numbers 41556-26-7 and 82919-37-7, which denote its composition as a mixture of Bis(1,2,2,6,6-pentamethyl-4-piperdimyl)-sebacate and 1-(Methyl)-8-(1,2,2,6,6-pentamethyl-4-piperidinyl)-sebacate. Unlike traditional UV absorbers that filter UV light, HALS like UV-292 operate through a sophisticated mechanism: they do not absorb UV radiation directly. Instead, they act as powerful scavengers for the free radicals generated during the photo-oxidation process. This unique mode of action allows HALS to inhibit the degradation of polymers that have already formed free radicals, effectively slowing down or halting the photochemical degradation reactions. A key advantage of HALS is their regeneration during the stabilization process, meaning they are not consumed, thereby providing long-term and highly efficient protection to both the bulk and surface of the polymer material.

The properties of UV-292 make it an ideal choice for a wide array of applications. It presents as a colorless to light yellow transparent liquid, boasting an effective content of ≥96% (GC). Its physical characteristics include a relative density of 0.99g/cm³ at 20℃, a viscosity of 400mPa•s at 20℃, and a color value of less than 50. With a freezing point of ≤-10℃, ash content ≤0.1%, and volatile content ≤0.5%, UV-292 maintains excellent stability and purity. Furthermore, its impressive light transmittance, at ≥98% at 425 nm and ≥99% at 500 nm, ensures minimal impact on the original color and clarity of the protected material.

The primary application of UV-292 lies in effectively preventing coatings from degrading under sun exposure. It significantly helps in maintaining gloss, preventing cracking, avoiding the formation of spots, and inhibiting blistering and surface peeling. This dramatically extends the lifespan of coatings. UV-292 demonstrates excellent compatibility with various coating series, performing exceptionally well in critical applications such as automotive coatings and UV-curable coatings. It also exhibits a powerful synergistic effect when combined with ultraviolet absorbers, enhancing overall protection.

Beyond coatings, UV-292 is highly suitable for integration into diverse polymer systems. It is particularly effective in polyolefins, unsaturated polyesters, and polymethacrylates. Its exceptional solubility in solvents makes it especially recommended for polyurethane applications, where it can be seamlessly incorporated. Other key applications include industrial coatings, coil coatings, wood color coatings, and mixed coatings. It also finds extensive use in radiation-curable coatings and inks, encompassing a broad range of formulations such as latex paints, air-drying alkyd paints, oil-based paints, single or dual-component polyurethanes, single and dual-component epoxy resins, clear lacquers, thermosetting and thermoplastic acrylates, polyesters, and phenolic and ethyl-based systems. By safeguarding against photodegradation, UV-292 helps preserve the structural integrity and aesthetic appeal of finished products, offering improved color retention and enhanced mechanical properties over time.
