Description

2-Methylundecyl Acrylate is a specialized long-chain alkyl acrylate monomer with a branched hydrocarbon tail. This molecular structure is critical for imparting unique properties to polymers, such as enhanced hydrophobicity, flexibility, and low-temperature performance. It is primarily sought after by formulators and polymer chemists in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of specialty plastics and additives.

Application

• Pressure-Sensitive Adhesives (PSAs): Imparts low surface energy and improved tack for labels and tapes.
• UV-Curable Coatings and Inks: Serves as a reactive diluent to modify viscosity and enhance film flexibility and adhesion.
• Acrylic Polymer Modifier: Used as a co-monomer to lower the glass transition temperature (Tg) and improve the low-temperature impact resistance of acrylic resins.
• Textile and Leather Finishes: Contributes to soft, durable, and water-repellent surface treatments.
• Specialty Lubricant Additives: Acts as a precursor for viscosity index improvers and pour point depressants.
• Emulsion Polymers: Used in the synthesis of latex for paints, caulks, and non-woven binders to enhance water resistance.

Quality Control

Our 2-Methylundecyl Acrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and inhibitor content are provided to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. Incompatible with strong acids and oxidizing agents. To prevent premature polymerization, maintain the recommended inhibitor level (typically MEHQ) and monitor storage conditions.
