Description

N,N,N',N'-Bis(1,2-Ethanediyl)-N''-(1-Oxyl-2,2,6,6-Tetramethyl-4-Piperidinylaminocarbonyl)Phosphoric Triamide is a specialized phosphoric triamide derivative featuring a stable nitroxyl radical (TEMPO) moiety, making it a highly effective and versatile functional additive. This compound is valued for its ability to impart radical scavenging and stabilization properties to polymeric materials, significantly enhancing their durability and performance under demanding conditions. It is primarily sought by manufacturers in the polymer, coatings, and advanced materials industries seeking to improve product longevity and resistance to thermal and oxidative degradation.

Application

• Polymer Stabilizer: Acts as a high-performance antioxidant and light stabilizer in engineering plastics, polyolefins (e.g., PP, PE), and synthetic fibers to prevent chain scission and discoloration.
• Advanced Coatings & Resins: Incorporated into automotive, industrial, and protective coatings to enhance weatherability, gloss retention, and resistance to thermal-oxidative aging.
• Radical Polymerization Modifier: Utilized as a nitroxide-mediated polymerization (NMP) agent or regulator to control polymer architecture and molecular weight distribution.
• Adhesives & Sealants: Improves the long-term thermal stability and prevents premature curing or embrittlement in high-performance adhesive formulations.
• Elastomer Protection: Extends the service life of synthetic rubbers and elastomeric components by protecting against ozone and oxygen-induced degradation.
• Research & Development: Serves as a key intermediate or functional additive in the R&D of novel materials, including organic electronics and advanced composites.
