Description

2-Ethylhexyl Methacrylate is a high-purity, monofunctional acrylate ester monomer characterized by its long hydrophobic alkyl chain. This chemical structure is critical for imparting flexibility, low-temperature performance, and water resistance to polymer chains. It is an essential raw material for formulators and polymer chemists in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and application properties.

Application

• Acrylic Polymer Production: A key monomer for manufacturing acrylic resins and copolymers used in paints, varnishes, and industrial coatings.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack, peel strength, and flexibility to adhesive tapes and labels.
• UV-Curable Systems: Used in inks, coatings, and 3D printing resins that cure rapidly under ultraviolet light.
• Textile and Leather Finishes: Modifies polymers to create durable, flexible, and water-repellent finishes.
• Plastic Modifiers: Acts as an internal plasticizer for PVC, acrylics, and other polymers to improve impact resistance and processability.
• Sealants and Caulks: Enhances elasticity and adhesion in construction and automotive sealant formulations.

Quality Control

Our 2-Ethylhexyl 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 all test results are provided with each shipment to guarantee traceability and batch-to-batch consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). The product contains an inhibitor (typically MEHQ) to prevent premature polymerization; maintain recommended storage conditions to ensure inhibitor efficacy and product stability.
