ABSTRACT:
The present invention provides a UV curable composition comprising an acrylate component, comprising an acrylate-functionalized hydrogenated polybutadiene, and at least one mono-functional acrylate, and a photoinitiator combination triggered upon exposure to radiation at 365 nm of the electromagnetic spectrum comprising a bisacyl phosphine oxide and benzophenone, where when dispensed at a thickness of about 1 mm and exposed to UV radiation generated at a wavelength of 365 nm the composition cures through the thickness of the dispensed composition at a speed between 40 mm/sec to 100 mm/sec.
