Description

Isoundecyl Methacrylate is a high-purity, long-chain alkyl methacrylate monomer essential for creating polymers with tailored properties. This compound is valued for its ability to impart low-temperature flexibility, hydrophobicity, and excellent weatherability to acrylic copolymers. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and specialty polymer industries seeking to enhance product performance.

Application

• UV-Curable Coatings & Inks: Used as a reactive diluent and modifier to improve flexibility, adhesion, and chemical resistance in formulations for wood, plastic, and metal substrates.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to lower the glass transition temperature (Tg) of acrylic polymers, enhancing tack and low-temperature performance.
• Acrylic Resin Modification: Serves as a co-monomer to introduce internal plasticization, improving impact resistance and durability in automotive, industrial, and architectural coatings.
• Specialty Elastomers & Sealants: Imparts hydrophobicity and resistance to oils and fuels in elastomeric compounds used for gaskets, O-rings, and construction sealants.
• Lubricant & Fuel Additives: Acts as a precursor for viscosity index improvers and pour-point depressants in high-performance lubricants and industrial fluids.
• Dental & Biomedical Materials: Employed in the synthesis of biocompatible polymers for dental composites and controlled-release matrices, subject to appropriate purity grades.

Quality Control

Our Isoundecyl Methacrylate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and assay, to ensure it meets precise specifications for monomer content and inhibitor levels. Certificates of Analysis (COA) documenting identity, purity, and physical properties are provided with each shipment to guarantee traceability and consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to its nature as a polymerizable monomer stabilized with an inhibitor, contact with strong acids, oxidizing agents, and free radical initiators should be avoided to prevent hazardous polymerization.
