1,6-Hexanediol diacrylate (HDDA or HDODA) is a difunctional acrylate ester monomer used in the manufacture of polymers.{{Cite web|url=https://pubchem.ncbi.nlm.nih.gov/compound/25644|title=1,6-Hexanediol diacrylate|last=PubChem|website=pubchem.ncbi.nlm.nih.gov|language=en|access-date=2020-02-12}}{{Cite web|url=http://www.chemspider.com/Chemical-Structure.23890.html|title=1,6-Hexanediol diacrylate {{!}} C12H18O4 {{!}} ChemSpider|website=www.chemspider.com|access-date=2020-02-12}} It is particularly useful for use in ultraviolet light cure applications.{{Cite web|url=https://ir.uiowa.edu/cgi/viewcontent.cgi?article=3559&context=etd|title=Industrially relevant epoxy-acrylate hybrid resin photopolymerizations|last=Ajiboye|first=Gbenga|date=2012|website=|url-status=dead|archive-url=https://web.archive.org/web/20131125034635/http://ir.uiowa.edu:80/cgi/viewcontent.cgi?article=3559&context=etd |archive-date=2013-11-25 |access-date=}} Furthermore, it is also used in adhesives, sealants, alkyd coatings, elastomers, photopolymers, and inks for improved adhesion, hardness, abrasion and heat resistance.{{Citation|title=Abrasion Resistance Testing-Vehicle Exterior Graphics and Pin Striping|publisher=SAE International|doi=10.4271/j1847_198906}} Like other acrylate monomers it is usually supplied with a radical inhibitor such as hydroquinone added.{{Cite web|url=https://www.alfa.com/en/catalog/043203/|title=13048-33-4 - 1,6-Hexanediol diacrylate, 99% (reactive esters), stab. with 90ppm hydroquinone - HDODA - 43203 - Alfa Aesar|website=www.alfa.com|access-date=2020-02-27}}
