Description

2-Propenoic Acid, 2-Methyl-, C11-14-Isoalkyl Esters, C13-Rich is a high-performance, branched-chain methacrylate ester monomer, specifically engineered with a high concentration of C13 isoalkyl groups. This composition provides a unique balance of properties, including excellent hydrophobicity, low volatility, and enhanced flexibility, making it a valuable reactive intermediate for advanced polymer synthesis. It is essential for formulators and manufacturers in the coatings, adhesives, and specialty polymers industries seeking to improve the durability and performance characteristics of their final products.

Application

• UV-Curable Coatings & Inks: As a reactive diluent and crosslinking agent to formulate low-viscosity, high-performance coatings with excellent adhesion and chemical resistance.
• Pressure-Sensitive Adhesives (PSAs): To modify acrylic polymer backbones, enhancing tack, peel strength, and cohesion for labels and tapes.
• Acrylic Resin Modification: Imparts flexibility, weatherability, and hydrophobicity to acrylic copolymers used in industrial and architectural paints.
• Lubricant & Fuel Additives: Serves as a precursor for polymeric additives that improve viscosity index and dispersancy.
• Specialty Elastomers & Sealants: Used in the synthesis of acrylic rubbers and sealants requiring low-temperature flexibility and oil resistance.
• Personal Care Polymers: For the production of film-forming agents and fixative polymers in hairsprays and styling gels.

Quality Control

Our production of 2-Propenoic Acid, 2-Methyl-, C11-14-Isoalkyl Esters, C13-Rich adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for assay and composition, to ensure consistency and meet precise customer specifications. Certificates of Analysis (COA) documenting purity, color, acid value, and moisture content are available upon request, supporting your quality assurance and regulatory compliance needs.

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). Keep container tightly sealed when not in use to prevent moisture absorption and maintain product integrity.
