Description

Octacosyl Methacrylate is a long-chain alkyl methacrylate monomer, a crucial building block for synthesizing specialty polymers with unique surface-modifying properties. Its high molecular weight alkyl tail imparts exceptional hydrophobicity, lubricity, and compatibility with non-polar matrices, making it invaluable for advanced material formulations. This product is essential for R&D and production in sectors such as coatings, adhesives, and high-performance plastics, where tailoring surface characteristics and polymer performance is paramount.

Application

• Surface Modifier for Coatings: Imparts water repellency, slip resistance, and stain release properties to industrial and architectural coatings.
• Internal Lubricant/Processing Aid: Enhances the flow and mold release of engineering plastics and composites during high-temperature processing.
• Hydrophobic Additive for Adhesives & Sealants: Improves moisture resistance and weatherability of acrylic-based pressure-sensitive adhesives and sealants.
• Monomer for Comb/Graft Polymers: Serves as a key monomer for synthesizing polymers with long alkyl side chains used as viscosity index improvers or dispersants.
• Paper & Textile Treatment: Used in formulations to create oil- and water-resistant barriers on paper, cardboard, and textiles.
• Specialty Resin Synthesis: A component in the production of resins for inks, toners, and photopolymers requiring specific rheological and film-forming properties.

Quality Control

Our Octacosyl Methacrylate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure consistency and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to guarantee traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from strong acids, oxidizing agents, and sources of ignition. For long-term storage, consider under an inert atmosphere to prevent potential polymerization.
