Description

Isononyl Acrylate is a high-purity, monofunctional acrylate ester monomer characterized by its long hydrophobic alkyl chain. This chemical structure is critical for imparting flexibility, low-temperature performance, and enhanced water resistance to polymer formulations. It is an essential raw material for manufacturers in the coatings, adhesives, and specialty polymers sectors seeking to improve product durability and application properties. The compound is supplied under strict quality control to ensure batch-to-batch consistency for industrial applications.

Application

• UV-Curable Coatings and Inks: A key monomer for formulating radiation-curable systems, providing excellent cure speed, adhesion, and flexibility on various substrates.
• Pressure-Sensitive Adhesives (PSAs): Used to synthesize acrylic copolymers that offer a balance of tack, peel strength, and shear resistance, especially for low-surface-energy materials.
• Acrylic Polymer Modifier: Serves as a comonomer to internally plasticize polymers, improving low-temperature flexibility and reducing the minimum film formation temperature (MFFT).
• Sealants and Caulks: Imparts durability, water repellency, and weatherability to elastomeric sealant formulations.
• Textile and Leather Finishes: Employed in polymers for coatings that require soft hand feel, flexibility, and resistance to washing and dry cleaning.
• Specialty Acrylic Resins: A building block for resins used in industrial maintenance coatings, automotive refinish, and plastic coatings.

Quality Control

Our Isononyl Acrylate is manufactured and tested under a stringent quality management system. Each 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 every shipment. Our quality commitment ensures reliability for your sensitive polymerization processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and direct sunlight. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Due to its highly volatile and light-sensitive nature, containers must be kept tightly sealed when not in use to prevent evaporation and quality degradation. Keep away from oxidizing agents, acids, and bases.
