Description

1-Methylpentyl Acrylate is a specialized acrylate ester monomer characterized by its branched alkyl chain. This structural feature is critical for modifying polymer properties, offering enhanced flexibility, hydrophobicity, and low-temperature performance in final materials. It is an essential raw material for polymer chemists and formulators in the coatings, adhesives, and specialty plastics industries seeking to fine-tune material characteristics.

Application

• Pressure-Sensitive Adhesives (PSAs): Imparts tack and improves low-temperature flexibility and adhesion to low-energy surfaces.
• Acrylic Polymer & Resin Synthesis: Serves as a co-monomer to create copolymers with tailored glass transition temperatures (Tg) and enhanced solubility.
• UV-Curable Coatings and Inks: Used as a reactive diluent to adjust viscosity and improve the final film's flexibility and chemical resistance.
• Textile and Leather Finishes: Incorporated into polymer emulsions to provide durable, soft-hand finishes with water-repellent properties.
• Sealants and Caulks: Enhances elasticity, adhesion, and weatherability in acrylic-based formulations.
• Specialty Acrylic Elastomers: A key component for producing high-performance elastomers with oil and solvent resistance.

Quality Control

Our 1-Methylpentyl Acrylate is manufactured under a stringent quality management system. Every batch is analyzed to ensure it meets precise specifications for purity, identity, and performance-critical parameters. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee supply consistency and reliability 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 oxidizers, acids, and bases. Recommended storage temperature is 2-8°C to maximize inhibitor efficacy and shelf life. Allow the material to reach ambient temperature before opening to prevent moisture condensation.
