Abstract
Photocurable (meth)acrylate compositions with low viscosity when uncured, and high flexibility and shear/tensile strength when cured, further possessing rapid tack-free fixture times, comprising mixtures of urethane acrylate resin, isobornyl acrylate, N,N-dimethylacrylamide, a photoinitiator component, and a low percentage of tetrahydrofurfuryl acrylate, for example from about 9% to about 15% by weight based on the weight of the composition. Applications can include adhesive bonding of medical tubing, UV/Visible transparent plastics material medical devices or equipment, or other flexible UV/Visible transparent material substrates.
