Description

2-Methyloctadecyl Methacrylate is a high-purity, long-chain alkyl methacrylate monomer designed for advanced polymer synthesis. This specialty chemical is valued for its ability to impart unique hydrophobic, lubricating, and low-temperature flexibility properties to polymer chains. It is essential for R&D and production in industries requiring tailored performance materials, such as high-performance coatings, advanced lubricants, and specialty adhesives.

Application

• High-Performance Coatings: Used as a co-monomer to enhance water repellency, chemical resistance, and surface lubricity in industrial, marine, and automotive coatings.
• Specialty Adhesives & Sealants: Imparts flexibility and hydrophobic character to pressure-sensitive adhesives (PSAs) and sealants for demanding environments.
• Lubricant & Fuel Additives: Serves as a key intermediate in the synthesis of polymeric viscosity index improvers and pour-point depressants for engine oils and hydraulic fluids.
• Surface Modifiers & Release Agents: Incorporated into polymers to create non-stick surfaces, mold release agents, and anti-fouling coatings.
• Personal Care Polymers: Used in the synthesis of film-forming agents, hair fixatives, and water-resistant ingredients for cosmetic formulations.
• Advanced Material Research: A critical building block in academic and industrial R&D for developing novel copolymers with tailored thermal and mechanical properties.

Quality Control

Our 2-Methyloctadecyl Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Infrared Spectroscopy (IR), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen) to prevent oxidation. Keep away from heat, sparks, and open flame. Isolate from strong oxidizing agents.
