Description

n-Octadecyl Methacrylamide is a high-purity, long-chain alkyl methacrylamide derivative, a crucial specialty monomer for advanced polymer synthesis. Its primary value lies in imparting exceptional hydrophobicity, oleophobicity, and low surface energy properties to copolymers and surface coatings. This compound is essential for R&D chemists and formulators in the polymer, coatings, and specialty materials industries seeking to create high-performance, functionalized materials.

Application

• Hydrophobic & Oleophobic Coatings: A key monomer for synthesizing polymers used in water- and oil-repellent surface treatments for textiles, paper, and leather.
• Surface Modifiers: Used to create low-surface-energy additives for paints, inks, and coatings to improve leveling, scratch resistance, and anti-fouling properties.
• Specialty Adhesives & Sealants: Incorporated to enhance the moisture resistance and durability of pressure-sensitive adhesives and industrial sealants.
• Lubricant & Fuel Additives: Serves as a precursor for polymeric additives that improve viscosity index and provide dispensancy in lubricants.
• Biomaterial Functionalization: Employed in research to modify surfaces of medical devices or create biocompatible polymer hydrogels with tailored properties.
• Emulsion Stabilizers: Acts as a co-monomer to stabilize polymer emulsions and latexes in industrial applications.

Quality Control

Our n-Octadecyl Methacrylamide is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure high chemical purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider keeping under an inert atmosphere (nitrogen or argon) to maintain stability and prevent degradation.
