Description

Isooctyl Acrylate is a high-purity, monofunctional acrylate ester monomer characterized by its long alkyl chain. This compound is essential for imparting flexibility, hydrophobicity, and low-temperature performance to polymer systems. It is a critical raw material for formulators and manufacturers in the adhesives, coatings, and specialty polymers industries seeking to enhance product durability and application properties.

Application

• Pressure-Sensitive Adhesives (PSAs): A key monomer for producing acrylic-based PSAs with excellent tack, peel adhesion, and low-temperature flexibility for tapes and labels.
• UV-Curable Coatings & Inks: Used as a reactive diluent to reduce viscosity and improve cure speed, flexibility, and chemical resistance in radiation-curable formulations.
• Acrylic Polymer Modifier: Incorporated as a co-monomer to plasticize and internalize flexibility into acrylic resins for coatings, sealants, and elastomers.
• Textile & Leather Finishes: Employed in polymers that provide durable, soft-hand, and water-repellent finishes to fabrics and leather goods.
• Construction & Sealants: Enhances the elasticity, adhesion, and weather resistance of acrylic-based caulks, sealants, and construction chemicals.
• Specialty Additives: Serves as a chemical intermediate in the synthesis of lubricant additives, surfactants, and other functional chemicals.

Quality Control

Our Isooctyl Acrylate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and purity, to ensure it meets exacting industry specifications for monomer reactivity and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15-25°C (59-77°F). This product is easily oxidized (store under inert atmosphere) and is compatible with strong acids and organic solvents. Keep away from heat, sparks, and open flame. For long-term storage, blanket with an inert gas such as nitrogen and monitor inhibitor levels.
