Description

Isododecyl Methacrylate is a high-purity, long-chain alkyl methacrylate monomer. This compound is valued for its ability to impart low-temperature flexibility, hydrophobicity, and excellent weathering resistance to polymer systems. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product performance.

Application

• UV-Curable Coatings & Inks: A key monomer for formulating low-viscosity, fast-curing systems with improved adhesion and flexibility on various substrates.
• Pressure-Sensitive Adhesives (PSAs): Used to modify acrylic polymers, providing enhanced tack, peel strength, and low-temperature performance.
• Acrylic Resin Modification: Imparts internal plasticization to acrylic copolymers, improving impact resistance and weatherability without migration.
• Lubricant & Fuel Additives: Serves as a precursor for viscosity index improvers and pour-point depressants in industrial lubricants and fuels.
• Fiber Optic Coatings: Employed in coatings that protect optical fibers, offering crucial mechanical protection and environmental stability.
• Automotive & Industrial Coatings: Enhances the durability, gloss retention, and chip resistance of exterior coatings and primers.

Quality Control

Our Isododecyl Methacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and assay, to ensure it meets precise specifications for color, acid value, and inhibitor content. Certificates of Analysis (COA) are provided with every shipment to guarantee traceability and compliance with customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to the presence of a polymerization inhibitor, storage under an inert atmosphere is recommended for long-term stability. Isolate from strong acids and oxidizing agents.
