Product Overview
Hexamethylene Diacrylate (HDDA), also known as 1,6-Hexanediol Diacrylate, is a difunctional acrylate monomer containing two polymerizable carbon-carbon double bonds. Its molecular structure combines a six-carbon aliphatic spacer with two acrylate functional groups, making it useful as a reactive component in UV-curable and radiation-curable formulations.
HDDA participates in free-radical polymerization and can contribute to the formation of crosslinked polymer structures. It is commonly considered for use in UV-curable coatings, printing inks, adhesives and other specialty resin systems. Its suitability depends on the formulation, curing conditions and the properties required in the finished material.
Hexamethylene Diacrylate is generally produced through the esterification of 1,6-hexanediol with acrylic acid or an acrylic acid derivative. The resulting material is processed and purified to meet the required product specifications. Commercial products may contain polymerization inhibitors to help maintain stability during storage and transportation.
Safety and Storage
Hexamethylene Diacrylate is a reactive acrylate monomer. Direct contact may cause skin or eye irritation and allergic skin reactions. Avoid inhalation of mist or vapor and use appropriate protective equipment and ventilation. Store in a tightly closed, compatible container under the conditions specified in the supplier's Safety Data Sheet (SDS). Protect from excessive heat and direct sunlight. Follow the supplier's recommendations regarding inhibitor content and storage conditions.
