Description

Tetrakis(2,2,6,6-Tetramethyl-4-Piperidyl) Butane-1,2,3,4-Tetracarboxylate is a high-performance, sterically hindered amine light stabilizer (HALS) of the polymeric type. This compound is critical for protecting polymers from the degrading effects of UV radiation and thermal oxidation, thereby significantly extending the service life of finished products. It is an essential additive for manufacturers in the plastics, coatings, and synthetic fiber industries who require long-term durability and color stability for their materials exposed to outdoor environments.

Application

• Polyolefin Stabilization: Primary use as a light and heat stabilizer in polypropylene (PP) and polyethylene (PE) for automotive parts, geotextiles, and outdoor furniture.
• Engineering Plastics: Enhances weatherability in polyamide (PA), polycarbonate (PC), and other engineering plastics used in exterior automotive components and construction materials.
• Coatings and Paints: Provides long-term gloss retention and prevents chalking and cracking in industrial and automotive coatings.
• Adhesives and Sealants: Improves the durability and performance lifespan of polyurethane and other polymer-based adhesives and sealants.
• Synthetic Fibers: Used in the spin finish and bulk polymerization of polypropylene and polyethylene fibers for outdoor applications like artificial turf and tarpaulins.
• Masterbatch Production: A key active component in UV-stabilizer and antioxidant concentrate masterbatches for easy compounding.

Quality Control

Our production of Tetrakis(2,2,6,6-Tetramethyl-4-Piperidyl) Butane-1,2,3,4-Tetracarboxylate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure consistency and compliance with industry specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and physical properties is provided with each shipment to guarantee traceability and quality assurance for our global B2B clients.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial opening to prevent moisture absorption, which can affect product performance.
