Description

n-Undecyl Methacrylate is a long-chain alkyl methacrylate monomer, a key building block for specialty polymers. Its primary value lies in imparting low surface energy, flexibility, and hydrophobicity to acrylic copolymers. This compound is essential for formulators and manufacturers in the coatings, adhesives, and advanced materials sectors seeking to enhance product performance.

Application

• Pressure-Sensitive Adhesives (PSAs): Imparts internal plasticization, improving low-temperature flexibility and tack.
• Coatings and Paints: Used as a co-monomer to enhance water repellency, weatherability, and gloss in industrial and architectural coatings.
• Oil & Gas Additives: A key component in polymers for pour point depressants and flow improvers in crude oil and fuel formulations.
• Textile and Leather Finishes: Provides soft hand feel, durability, and water resistance to treated fabrics and leathers.
• UV-Curable Resins: Serves as a reactive diluent to reduce viscosity while contributing to film flexibility and adhesion.
• Specialty Elastomers and Sealants: Enhances low-temperature performance and resistance to oils and chemicals.

Quality Control

Our n-Undecyl Methacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and assay, to ensure it meets precise specifications for monomer content and impurity profiles. Certificates of Analysis (COA) documenting identity, purity, and key physical properties are available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C under an inert atmosphere (e.g., nitrogen) to prevent oxidation and polymerization. Keep away from heat, sparks, and open flame. Monitor inhibitor content (typically MEHQ) as per the technical data sheet.
