Description

Isononyl Methacrylate is a high-purity, monofunctional methacrylate monomer characterized by its long alkyl chain. This compound is essential for imparting flexibility, hydrophobicity, and low-temperature properties to polymer chains. It is a critical raw material for formulators in the coatings, adhesives, and specialty plastics industries seeking to enhance product performance.

Application

• Coatings & Paints: Used as a co-monomer in UV-curable, radiation-curable, and solvent-based coatings to improve flexibility, adhesion, and water resistance.
• Adhesives & Sealants: Imparts low shrinkage, enhanced tack, and improved weatherability to acrylic-based pressure-sensitive adhesives (PSAs) and structural adhesives.
• Acrylic Resins & Plastics: Serves as a comonomer to modify the glass transition temperature (Tg), increase impact resistance, and improve the low-temperature performance of acrylic sheets and molding compounds.
• Lubricant & Fuel Additives: Employed in the synthesis of polymeric additives that improve viscosity index and provide dispersancy.
• Printing Inks: A key component in flexographic and screen printing inks, contributing to fast curing and excellent substrate wetting.
• Fiber Optic Coatings: Used in formulations for primary and secondary coatings to provide mechanical protection and environmental stability.

Quality Control

Our Isononyl 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 exacting specifications for monomer content and inhibitor levels. Certificates of Analysis (COA) detailing all test results are provided with each shipment to guarantee traceability and batch-to-batch consistency.

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). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flames. For long-term storage, maintaining a nitrogen blanket is recommended to prevent premature polymerization.
