1,6-Hexanediol diacrylate
1,6-hexanediol diacrylate is a difunctional acrylate ester monomer used in the manufacture of polymers. It is particularly useful for use in ultraviolet light cure applications. Furthermore, it is also used in adhesives, sealants, alkyd coatings, elastomers, photopolymers, and inks for improved adhesion, hardness, abrasion and heat resistance. Like other acrylate monomers it is usually supplied with an inhibitor such as hydroquinone added It has the CAS number of 13048-33-4.Preparation
The material is prepared by acid-catalyzed esterification of 1,6-hexanediol with acrylic acid.Other uses
As the molecule has acrylic functionality, it is capable of doing the Michael reaction with an amine. This allows it use in epoxy chemistry where its use speeds up the cure time considerably.
