Description

4-Methylpentyl Acrylate is a specialized acrylate ester monomer known for its hydrophobic nature and ability to impart low glass transition temperatures (Tg) to polymer systems. This compound matters for formulators seeking to enhance the flexibility, water resistance, and low-temperature performance of acrylic polymers. Industries that need it include advanced coatings, pressure-sensitive adhesives, and specialty polymer manufacturing, where it serves as a key building block for high-performance materials.

Application

• Pressure-Sensitive Adhesives (PSAs): A key monomer for formulating acrylic-based PSAs with excellent tack, peel strength, and low-temperature flexibility.
• Coatings and Paints: Used in industrial, automotive, and architectural coatings to improve film-forming properties, water repellency, and durability.
• Textile and Leather Finishes: Imparts softness, water resistance, and improved handle to treated fabrics and leathers.
• UV-Curable Resins & Inks: Acts as a reactive diluent and crosslinker in radiation-curable systems for fast, low-VOC applications.
• Plasticizers and Modifiers: Employed to internally plasticize acrylic polymers, reducing brittleness and enhancing impact resistance.
• Specialty Polymer Synthesis: Serves as a monomer for creating custom copolymers with tailored properties for niche industrial applications.

Quality Control

Our 4-Methylpentyl Acrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications for industrial polymerization. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, strong acids, and oxidizing agents. Recommended storage temperature is 15-25°C. The product is light-sensitive and should be stored away from direct light exposure. Keep container tightly sealed when not in use to prevent moisture absorption and polymerization.
