Description

Iso-Decyl Methacrylate is a high-purity, monofunctional methacrylate monomer characterized by its long, branched alkyl chain. This structural feature is critical for imparting exceptional flexibility, hydrophobicity, and low-temperature performance to polymer formulations. It is an essential raw material for industrial chemists and formulators seeking to enhance the properties of acrylic resins and specialty polymers. The compound, CAS NO 29964-84-9, is primarily utilized in the production of coatings, adhesives, and advanced materials where durability and environmental resistance are paramount.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and modifier to improve flexibility, adhesion, and weatherability in radiation-curable systems for wood, plastic, and metal substrates.
• Pressure-Sensitive Adhesives (PSAs): Used to synthesize acrylic copolymers that provide low-temperature tack, enhanced peel strength, and improved water resistance.
• Acrylic Resin Modification: Incorporated into acrylic polymer chains to act as an internal plasticizer, reducing brittleness and improving impact resistance without migration.
• Lubricant and Fuel Additives: Serves as a precursor for polymeric additives that improve viscosity index and pour point in lubricants and prevent deposit formation in fuels.
• Textile and Leather Finishes: Imparts softness, water repellency, and durability to finishing agents for fabrics and synthetic leather.
• Sealants and Caulks: Enhances elasticity, adhesion, and long-term durability in construction and automotive sealant formulations.

Quality Control

Our iso-Decyl Methacrylate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against rigorous internal specifications, which typically include assessment of identity, assay, color, moisture content, and inhibitor levels. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). The product contains an inhibitor (typically MEHQ) to prevent premature polymerization; ensure the inhibitor level is maintained within specification during storage.
