Description

2,2,3,3,4,4-Hexafluoro-1,5-Pentyl Dimethacrylate is a specialty fluorinated dimethacrylate monomer, distinguished by its unique hexafluoropentyl spacer linking two methacrylate groups. This compound is engineered to impart exceptional chemical resistance, low surface energy, and enhanced thermal stability to advanced polymer systems. It is a critical raw material for manufacturers in the optical, electronics, and high-performance coatings industries seeking to develop materials with superior durability and specific interfacial properties.

Application

• High-Performance Optical Resins & Coatings: Used to formulate low-refractive-index, high-transparency polymers for optical fibers, lenses, and anti-reflective coatings.
• Fluorinated Acrylic Polymers: Serves as a key monomer for synthesizing specialty fluoropolymers with outstanding resistance to chemicals, solvents, and weathering.
• Low Surface Energy & Release Coatings: Essential for creating non-stick, easy-clean, and anti-fouling surfaces in industrial and consumer applications.
• Electronics Encapsulation & Adhesives: Employed in potting compounds and adhesives for electronic components requiring excellent moisture barrier properties and dielectric performance.
• Advanced Composite Materials: Incorporated into the matrix of composites to enhance interfacial adhesion and environmental resistance.
• Hydrophobic & Oleophobic Surface Modifiers: Used as a surface treatment agent to impart water- and oil-repellent characteristics to textiles, papers, and membranes.

Quality Control

Our production of 2,2,3,3,4,4-Hexafluoro-1,5-Pentyl Dimethacrylate adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopy (IR, NMR), to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing specific batch results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids, bases, and sources of ignition. For long-term storage under inert atmosphere (e.g., nitrogen) is recommended to maintain monomer stability.
