Description

Bis(2,2,6,6-Tetramethyl-4-Piperidyl) 1,6-Hexanediylbis[(2,2,6,6-Tetramethyl-4-Piperidyl)Carbamate] is a high-performance, high molecular weight hindered amine light stabilizer (HALS) designed for superior long-term polymer protection. This compound is critical for preventing photo-oxidative degradation, thereby extending the service life and maintaining the mechanical properties and color of polymeric materials. It is an essential additive for manufacturers in the plastics, coatings, and synthetic fiber industries who require advanced UV stabilization for demanding applications.

Application

• Primary UV stabilizer for polyolefins, including high-density polyethylene (HDPE), low-density polyethylene (LDPE), and polypropylene (PP) films, fibers, and molded articles.
• Enhancing the light fastness and weatherability of automotive coatings, industrial paints, and wood coatings.
• Stabilization of engineering plastics such as polyamides (nylon), polycarbonates, and thermoplastic polyurethanes (TPU) used in outdoor applications.
• Protection of agricultural films and greenhouse covers from solar UV radiation to prolong functional lifespan.
• Additive for synthetic fibers and geotextiles to prevent strength loss and embrittlement caused by sunlight exposure.
• Use in adhesives and sealants to maintain elasticity and bonding performance under outdoor conditions.
• Stabilizer component for masterbatches and compound formulations targeting extended durability.

Quality Control

Our production of this hindered amine light stabilizer adheres to strict quality management systems, ensuring batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques like HPLC and GC to verify key parameters including assay, melting point, and residual solvent content. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
