Description

n-Octyl Acrylate is a high-purity, long-chain alkyl acrylate monomer essential for imparting flexibility, hydrophobicity, and low-temperature properties to polymer systems. Its primary value lies in its ability to act as a reactive diluent and co-monomer, significantly modifying the physical characteristics of acrylic resins and adhesives. This product is critical for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance product performance and durability.

Application

• Pressure-Sensitive Adhesives (PSAs): A key component for formulating acrylic-based PSAs with excellent tack, peel strength, and low-temperature flexibility for tapes and labels.
• Acrylic Resin Modification: Used as a co-monomer to produce soft, flexible, and hydrophobic acrylic polymers for coatings and binders.
• UV-Curable Coatings & Inks: Serves as a reactive diluent in radiation-curable systems, contributing to low viscosity, fast cure, and enhanced film properties.
• Textile & Leather Finishes: Imparts water repellency, softness, and durability to finishing agents for fabrics and leather goods.
• Sealants and Caulks: Enhances elasticity, adhesion, and weather resistance in acrylic-based sealant formulations.
• Emulsion Polymers: A valuable monomer for creating stable acrylic emulsions with tailored glass transition temperatures (Tg) for diverse industrial applications.
