  • CONDUCTIVE PHOTO-CURABLE COMPOSITIONS FOR ADDITIVE MANUFACTURING
    Publication number: 20220111582
    Abstract: A photo-curable composition for use in additive manufacturing, said composition comprising: a) at least one photocurable monomer or oligomer; b) a photoinitiator for polymerization of the monomer; and, from 0.01 to 1 wt. %, based on the weight of the composition, of c) CNS-derived materials. Following polymerization, the resulting polymerized composition has a volume resistivity no greater than 105 ohm·cm.

  • Low-viscosity photocurable adhesive compositions
    Patent number: 11299570
    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.
