1,6-Hexanediol dimethacrylate CAS 6606-59-3 HDDA

1,6-Hexanediol dimethacrylate is a colourless to light yellow transparent liquid with a slight irritating odour.As a crosslinking monomer, it is widely used in light-curing coatings, dental materials, acrylic resins and 3D printing photosensitive resins, giving products high hardness and weather resistance.It needs to be stored away from light, its active double bond is easy to polymerise, and it needs to be handled with protection to avoid skin/eye contact.
