Description

1,6-Hexanediol Dimethacrylate is a high-purity, difunctional methacrylate monomer characterized by its long-chain aliphatic structure. This compound is a critical crosslinking agent and building block in polymer chemistry, valued for its ability to impart enhanced flexibility, durability, and chemical resistance to final polymer networks. It is essential for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to develop high-performance, specialized products.

Application

• UV-Curable Coatings & Inks: A key monomer for formulating flexible, scratch-resistant, and weather-durable coatings for plastics, metals, and wood.
• Dental & Medical Composites: Used as a crosslinker in restorative resins and prosthetic materials to improve mechanical strength and reduce polymerization shrinkage.
• Adhesives & Sealants: Enhances the toughness and adhesion properties of acrylic-based structural and pressure-sensitive adhesives.
• Fiber Optic Coatings: Provides protective, flexible primary and secondary coatings that safeguard optical fibers.
• Photoresists & Electronics: Serves as a monomer in photopolymer formulations for printed circuit boards (PCBs) and microelectronics.
• Acrylic Sheet & Casting Resins: Imparts impact resistance and weatherability to cast acrylic sheets and molded parts.
• Nail Enhancements & Cosmetics: A component in gel polishes and artificial nail formulations for lasting wear and gloss.
• 3D Printing Resins (SLA/DLP): Used in stereolithography resins to create durable, high-resolution printed objects with good mechanical properties.

Quality Control

Our 1,6-Hexanediol Dimethacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications for color, acidity, and inhibitor content. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to its reactivity, store separately from strong acids, bases, and oxidizing agents. For long-term stability, maintain under an inert atmosphere (e.g., nitrogen) and monitor inhibitor levels.
