  • Patent number: 9701775
    Abstract: Photopolymer resin formulation for 3D printing enhancing the performance of 3D printed objects. In one example, additives comprising two photoinitiators with different absorption spectrums are used to achieve printing and post-curing processes. A thermal initiator can also be used to complete the post-curing process by baking at appropriate temperature. Additive combinations balanced to absorb some light in the near UV range of about 400 nm to about 420 nm absorption wavelength band or spectrum while fluorescing light at frequencies higher than their absorption wavelength allowing the creation of clear transparent materials using only near UV light sources (i.e., about 400 nm to about 420 nm) instead of deep UV (<400 nm) light sources.

  • Patent number: 7563831
    Abstract: A method for curing a chemical composition, the composition containing at least one or more binders having ethylenically unsaturated groups, as well as one or more initiators for triggering a radical polymerization. The method includes a thermal curing step, in which the curing of the composition is effected by a radical polymerization of the binder, which is triggered by a thermal initiator and is carried out under protective gas. Paint films having improved mechanical properties can be produced using the method according to the present invention.
