Description

n-Heptyl Methacrylate is a versatile, long-chain alkyl methacrylate monomer essential for creating polymers with tailored properties. Its value lies in its ability to impart low glass transition temperatures, flexibility, and hydrophobic characteristics to acrylic copolymers. This makes it a critical raw material for formulators in the coatings, adhesives, and specialty polymer industries seeking to enhance product performance and durability.

Application

• Acrylic Resin Modification: Used as a co-monomer to lower the glass transition temperature (Tg) and improve the flexibility and low-temperature performance of acrylic resins.
• Specialty Coatings & Inks: Imparts excellent water resistance, weatherability, and adhesion to metal and plastic substrates in automotive, industrial, and decorative coatings.
• Pressure-Sensitive Adhesives (PSAs): Enhances tack, peel strength, and shear resistance in adhesive formulations for tapes and labels.
• Lubricant & Fuel Additives: Serves as a precursor for polymeric additives that improve viscosity index and dispersancy.
• Fiber & Textile Treatment: Utilized in surface modifiers and finishing agents to provide water-repellent and soft-hand properties.
• Optical Polymers: Employed in the synthesis of polymers for lenses and optical films due to its clarity and processability.

Quality Control

Our n-Heptyl Methacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets precise customer and industry specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat sources and incompatible materials such as strong oxidizers and bases. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). The product typically contains an inhibitor (e.g., MEHQ) to prevent polymerization during storage; please consult the specific COA for inhibitor content and handling instructions.
