Light Stabilizer 123

Product Overview

Light Stabilizer 123 is a high-performance hindered amine light stabilizer (HALS) engineered to provide exceptional ultraviolet protection for a wide range of polymeric materials and coating systems. As a critical additive in the specialty chemicals sector, this product functions by scavenging free radicals generated during UV exposure, thereby significantly extending the service life of substrates. Its unique chemical structure ensures minimal interaction with acidic components, making it particularly effective in alkyd-based coatings where traditional stabilizers might fail.

This liquid stabilizer is characterized by its high purity and excellent solubility, allowing for seamless integration into complex formulations. It serves as a robust solution for manufacturers seeking to enhance the durability and aesthetic retention of their finished products against environmental weathering.

Technical Specifications

Industrial Applications

The versatility of Light Stabilizer 123 makes it suitable for a diverse array of industrial applications. It is extensively used in the formulation of automotive coatings, where resistance to gloss loss and cracking is paramount. Additionally, it performs excellently in industrial coatings, decorative paints, and wood coatings, providing long-term protection against photodegradation.

Beyond coatings, this stabilizer is compatible with various resin systems including acrylics, polyurethanes, and unsaturated resins. It is also effective in plastics such as PVC, polypropylene, polystyrene, and thermoplastic elastomers (TPE/TPO). Its ability to cross-link with other components in the coating formulation enhances the overall integrity of the protective layer.

Performance Advantages

• Superior resistance to acids, flame retardants, sulfur, and catalyst residues.
• Weakly alkaline nature reduces adverse interactions with acidic coating components.
• Exceptional optical clarity with high transmittance values across visible light spectra.
• Effective inhibition of light loss, cracking, foaming, and peeling in finished products.
• Compatible for use in combination with UV absorbers such as UV-1130 or UV-928.

Storage and Handling

Light Stabilizer 123 exhibits good storage stability under recommended conditions. To maintain optimal quality, the product should be stored in a cool, dry, and well-ventilated area, protected from direct moisture and heat sources. High temperature and humidity should be avoided during transportation and warehousing. Standard packaging options include 25kg and 200kg plastic drums, ensuring safe delivery for bulk industrial orders. As a non-dangerous good, it facilitates easier logistics and handling compliance.
