Description

2-Methylheptadecyl Methacrylate is a high-molecular-weight methacrylate monomer characterized by its long, branched alkyl chain. This unique structure is critical for imparting exceptional hydrophobicity, flexibility, and low-temperature properties to polymer formulations. It is an essential raw material for manufacturers in the coatings, adhesives, and specialty polymers sectors seeking to enhance product performance. The compound is supplied under the CAS registry number 94159-01-0.

Application

• Pressure-Sensitive Adhesives (PSAs): Imparts excellent tack, peel strength, and low-temperature flexibility for tapes and labels.
• UV-Curable Coatings & Inks: Serves as a reactive diluent and modifier to improve adhesion, weatherability, and surface slip in radiation-curable systems.
• Acrylic Resin Modification: Used as a co-monomer to introduce internal plasticization, reducing the need for external plasticizers and enhancing the durability of acrylic polymers.
• Lubricant & Fuel Additives: Acts as a precursor for viscosity index improvers and pour point depressants in industrial lubricants and automotive fluids.
• Textile & Leather Finishes: Incorporated into polymer emulsions to create soft, water-repellent, and durable finishes on fabrics and leather goods.
• Specialty Elastomers: Enhances the oil resistance, flexibility, and elastic recovery of synthetic rubbers and thermoplastic elastomers.

Quality Control

Our 2-Methylheptadecyl 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 consistency and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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). Under these conditions, the product has a typical shelf life of 24 months from the date of manufacture.
