Description

Hexamethylene Diacrylate is a difunctional acrylic monomer characterized by its two reactive acrylate groups separated by a flexible hexamethylene spacer. This compound is a crucial building block in polymer chemistry, serving as a crosslinking agent that imparts enhanced hardness, chemical resistance, and durability to the final polymer network. It is primarily utilized by formulators and manufacturers in the production of advanced coatings, inks, adhesives, and photopolymer resins for 3D printing and stereolithography.

Application

• UV-Curable Coatings & Inks: Acts as a key crosslinker to create fast-curing, high-performance surface finishes with excellent abrasion and solvent resistance.
• Adhesives & Sealants: Enhances the cohesive strength and thermal stability of acrylic-based structural and pressure-sensitive adhesives.
• Photopolymer Resins: A fundamental component in resins for stereolithography (SLA) and other 3D printing technologies, contributing to part toughness and resolution.
• Dental & Medical Polymers: Used in the formulation of biocompatible polymers for dental composites and bone cements, where controlled crosslinking is essential.
• Fiber Optic Coatings: Provides protective, durable layers on optical fibers due to its excellent curing properties and resulting physical characteristics.
• Acrylic Sheet & Casting Resins: Improves the impact resistance and surface hardness of cast acrylic sheets and molded parts.

Quality Control

Our Hexamethylene Diacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, purity profiling, and impurity quantification, to ensure it meets the high standards required for industrial and specialty applications. A Certificate of Analysis (COA) detailing specific results for purity, color, acidity, and water content is provided with every shipment to guarantee traceability and consistency.

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). This product is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep away from heat, sparks, and open flame. For long-term storage, consider under an inert gas such as nitrogen to maintain optimal quality and inhibit premature polymerization.
