Description

n-Octyl Methacrylate is a high-purity, long-chain alkyl methacrylate monomer essential for imparting flexibility, hydrophobicity, and low-temperature performance to polymer systems. Its value lies in its ability to create copolymers with tailored properties for demanding industrial applications. This product is primarily needed by manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and functionality.

Application

• Coatings & Paints: Key monomer for formulating high-performance acrylic resins used in automotive, industrial, and marine coatings, providing excellent water resistance, flexibility, and gloss retention.
• Adhesives & Sealants: Used to modify pressure-sensitive adhesives (PSAs) and structural adhesives, improving tack, peel strength, and adhesion to low-energy surfaces.
• Plastic Modifiers: Serves as a comonomer in the production of impact modifiers and processing aids for PVC and other engineering plastics, enhancing toughness and flow characteristics.
• Fiber & Textile Treatment: Employed in the synthesis of polymers for fabric coatings and finishes, offering durable water repellency and soft hand feel.
• Lubricant & Fuel Additives: A precursor for viscosity index improvers and pour-point depressants in lubricating oils and industrial fluids.
• UV-Curable Systems: A reactive diluent and crosslinker in inks, overprint varnishes, and 3D printing resins cured by ultraviolet light.
• Personal Care Polymers: Used in the synthesis of film-forming agents and fixatives for hairsprays, sunscreens, and nail polish.
• Specialty Elastomers: Incorporated into acrylic rubber formulations to improve oil resistance and low-temperature flexibility for gaskets and seals.

Quality Control

Our n-Octyl Methacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and assay, to ensure it meets precise specifications for color, acidity, and inhibitor content. We provide comprehensive Certificates of Analysis (COA) with each shipment to guarantee traceability and compliance with your technical requirements.

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 to prevent polymerization; do not store under conditions that may lead to inhibitor depletion.
