Description

Isoicosyl Methacrylate is a high-molecular-weight methacrylate ester monomer, a key building block for specialty polymers. Its long, branched isoicosyl chain imparts unique properties to polymers, including excellent hydrophobicity, low-temperature flexibility, and enhanced compatibility with various resins and plasticizers. This monomer is essential for formulators and polymer chemists in the coatings, adhesives, and advanced materials sectors seeking to tailor the performance characteristics of acrylic copolymers.

Application

• High-Performance Coatings: Used as a co-monomer to formulate solvent-borne and radiation-curable coatings with improved water resistance, flexibility, and adhesion to low-energy surfaces.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack and enhances the cohesive strength and low-temperature performance of acrylic-based adhesive tapes and labels.
• Lubricant and Fuel Additives: Serves as a precursor for viscosity index improvers and pour-point depressants in engine oils and industrial lubricants.
• Printing Inks: Incorporated into ink formulations to improve pigment wetting, gloss, and rub resistance.
• Plastic Modification: Acts as a reactive modifier to enhance the impact resistance and processability of engineering plastics and thermoplastic elastomers.
• Sealants and Caulks: Contributes to the durability, elasticity, and weather resistance of acrylic polymer-based sealants.

Quality Control

Our Isoicosyl Methacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by GC, purity verification, and control of key impurities like inhibitor content and moisture. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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. The product typically contains an inhibitor (e.g., MEHQ) to prevent polymerization during storage; monitor inhibitor levels for long-term storage.
