Description

Isoundecyl Acrylate is a high-purity, monofunctional acrylate monomer characterized by its long, branched alkyl chain. This chemical structure is critical for modifying polymer properties, offering a unique balance of low volatility, excellent hydrophobicity, and enhanced flexibility. It is an essential raw material for formulators and polymer chemists in the coatings, adhesives, and specialty polymer industries seeking to improve product performance and durability.

Application

• UV-Curable Coatings and Inks: Acts as a reactive diluent to reduce viscosity, improve flow, and enhance the flexibility and weatherability of cured films.
• Pressure-Sensitive Adhesives (PSAs): Used to synthesize acrylic copolymers that provide superior tack, peel strength, and low-temperature performance.
• Acrylic Resin Modification: Incorporated into polymer backbones to impart internal plasticization, reducing the need for external plasticizers and improving resistance to extraction.
• Specialty Elastomers and Sealants: Enhances the low-temperature flexibility and hydrolytic stability of acrylic rubber and sealant formulations.
• Radiation-Curable Oligomers: Serves as a building block for synthesizing urethane acrylates and other oligomers with tailored properties for advanced curing applications.
• Fiber Optic Coatings: Contributes to the development of flexible, protective secondary coatings with excellent mechanical and environmental resistance.

Quality Control

Our Isoundecyl Acrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by GC, purity verification, and control of critical impurities like residual monomer and inhibitors. Certificates of Analysis (COA) documenting full specifications are provided to ensure traceability and compliance with your technical 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). Keep away from heat, sparks, and open flame. For long-term storage, it is recommended to maintain an inert atmosphere (e.g., nitrogen) to prevent premature polymerization.
