NINGBO INNO PHARMCHEM CO.,LTD. is pleased to announce the availability of High-Performance Liquid Light Stabilizer 292, a critical additive for extending the lifespan and performance of polymers, coatings, and inks. This product, known chemically as a mixture of compounds with CAS numbers 41556-26-7 and 82919-37-7, is a widely recognized and efficient Hindered Amine Light Stabilizer (HALS).

Light Stabilizer 292 functions by scavenging free radicals generated during photo-oxidation, effectively inhibiting the degradation process caused by ultraviolet (UV) radiation. Unlike traditional UV absorbers that filter UV light, HALS compounds work through a regenerative cycle, providing long-term protection even at low concentrations. This makes them indispensable for materials exposed to sunlight and weathering, preventing issues such as cracking, chalking, gloss loss, and color fading.

The liquid form of Light Stabilizer 292 offers distinct advantages in various manufacturing processes. Its low viscosity and good solubility in many organic solvents and polymers facilitate easier handling, incorporation, and dispersion compared to solid additives. This can lead to more uniform distribution within the final product, ensuring consistent protection throughout the material. The light yellowish, viscous liquid is easy to meter and mix, streamlining production processes and reducing potential errors.

Key properties of the Light Stabilizer 292 supplied by NINGBO INNO PHARMCHEM CO.,LTD. include its notable low volatility, which is crucial for applications involving high processing temperatures or demanding environmental conditions. Minimal volatile matter content (typically ≤ 0.5%) ensures the additive remains in the material over time, maintaining its protective function. Similarly, a low ash content (typically ≤ 0.1%) indicates high purity, which is important for applications requiring optical clarity or minimal interference with other additives.

Optical properties are also a highlight, with high transmittance values at relevant wavelengths (e.g., 425nm ≥ 98%, 500nm ≥ 99%). This ensures that the additive itself does not impart significant color or turbidity to clear or lightly colored formulations, which is particularly important in coatings and films where appearance is critical.

The primary applications for Light Stabilizer 292 are extensive. It is widely used in the coatings industry, including automotive finishes, industrial coatings, wood coatings, and decorative paints. In these applications, it is highly effective at preventing defects such as 'blowing-out' and surface peeling-off, especially when used in combination with benzotriazole UV absorbers, where it exhibits synergistic effects. This cooperative action provides enhanced and broader-spectrum protection against photodegradation.

Beyond coatings, Light Stabilizer 292 is vital in the plastics industry for polyolefins (such as polyethylene and polypropylene), engineering plastics, polyurethanes, and other polymers. It extends the service life of plastic products ranging from automotive parts and agricultural films to outdoor furniture and packaging materials. Its efficacy in polyurethane lacquers is also well-established, contributing to the durability of these finishes.
