Description

Isooctadecyl Acrylate is a high-purity, long-chain alkyl acrylate monomer essential for advanced polymer synthesis. This compound is valued for its ability to impart low-temperature flexibility, hydrophobicity, and excellent weatherability to acrylic polymers and copolymers. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance product performance.

Application

• Primary monomer for synthesizing pressure-sensitive adhesives (PSAs) with improved tack and peel strength.
• Key component in UV-curable resins and oligomers for coatings and inks, providing low shrinkage and enhanced flexibility.
• Modifier for acrylic emulsion polymers used in architectural and industrial paints to improve film formation and durability.
• Intermediate in the production of specialty surfactants and lubricant additives.
• Used in fiber and textile finishing agents to provide water-repellent and soft-hand properties.
• Building block for cross-linked polymers and hydrogels in personal care and medical applications.

Quality Control

Our Isooctadecyl Acrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets the high standards required for industrial polymerization processes. Certificates of Analysis (COA) documenting specific grade specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area under an inert atmosphere (e.g., nitrogen) to prevent oxidation and polymerization. Recommended storage temperature is 2-8°C to maximize shelf-life and inhibit premature reaction. Keep away from heat, sparks, and open flame.
