Description

4,6-Di-tert-Butyl-2-(3,5-Di-tert-Butyl-2-Hydroxyphenyl)-6-Morpholino-2,4-Cyclohexadien-1-One is a high-performance hindered phenolic antioxidant and light stabilizer. This compound is critical for protecting polymers and other materials from oxidative degradation and UV-induced damage, thereby extending their service life and maintaining their physical properties. It is primarily needed by manufacturers in the plastics, rubber, coatings, and specialty chemical industries who require advanced stabilization solutions for their formulations.

Application

• Polymer Stabilization: As a primary antioxidant in polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal-oxidative degradation during processing and end-use.
• UV Light Stabilizer: Functions as a light stabilizer in coatings, automotive parts, and outdoor plastic applications to protect against photodegradation and color fading.
• Synergistic Additive: Used in combination with secondary antioxidants (e.g., phosphites, thioesters) and HALS (Hindered Amine Light Stabilizers) for enhanced stabilization performance.
• Lubricant & Fuel Additive: Employed as an antioxidant additive in industrial lubricants, greases, and fuels to inhibit oxidation and sludge formation.
• Adhesive & Sealant Formulations: Incorporated to improve the aging resistance and durability of hot-melt adhesives, sealants, and elastomeric compounds.
• Specialty Chemical Intermediate: Serves as a key intermediate or building block in the synthesis of more complex antioxidant and stabilizer molecules.
