| description | The present disclosure relates generally to photocurable compositions and methods for continuously forming a three-dimensional body from these compositions. More particularly, the present disclosure relates to photocurable compositions comprising a mixture of polysiloxanes capable of being dually cured, i.e., first by UV radiation followed by thermal treatment, or being cured by UV radiation. In one aspect, the disclosure provides a photocurable composition, including: a first polysiloxane comprising at least two acrylate or methacrylate groups per molecule; a second polysiloxane containing at least one (e.g., at least two) Si-H group per molecule; a third polysiloxane containing at least one (e.g., at least two) reactive aliphatic ethylene group per molecule; a free radical photoinitiator in an amount of about 0.01 to about 10 weight % based on the total weight of (meth)acrylate-containing polysiloxane in the composition; and a hydrosilylation catalyst in an amount of about 0.001 to about 10 weight % hydride-containing polysiloxane and vinyl-containing polysiloxane in the composition. |
