Description

9,12-Octadecadienyl Methacrylate is a long-chain alkyl methacrylate monomer derived from linoleic acid, featuring a reactive methacrylate group and a C18 di-unsaturated tail. This unique structure provides excellent copolymerization characteristics and imparts flexibility, hydrophobicity, and enhanced adhesion to polymer backbones. It is primarily utilized by formulators and polymer chemists in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced material science for creating specialty polymers with tailored surface properties.

Application

• High-Performance Coatings: Used as a co-monomer in UV-curable, radiation-curable, and solvent-based coatings to improve flexibility, weather resistance, and adhesion to low-surface-energy substrates like plastics and metals.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to modify the viscoelastic properties, enhancing tack, peel strength, and cohesion in label and tape formulations.
• Specialty Elastomers & Sealants: Serves as a building block for acrylic rubbers and sealants, providing low-temperature flexibility and resistance to oils and oxidation.
• Surface Modifiers & Additives: Employed in the synthesis of polymeric surfactants, dispersants, and flow aids for pigment and filler systems.
• Lubricant & Fuel Additives: Used to create polymeric additives that improve viscosity index and provide detergent/dispersant properties.
• Biomedical & Dental Materials: Potential application in the development of biocompatible polymers and resin composites due to its hydrophobic nature.

Quality Control

Our 9,12-Octadecadienyl Methacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and optimal performance in your formulations. Certificates of Analysis (COA) detailing key parameters such as assay, identity, and impurity profile are available upon request for full traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15-25°C (59-77°F). Due to its unsaturated nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) to minimize oxidation. Keep away from heat, sparks, and open flames.
