Abstract
A polymer composition that includes a blended resin having a viscosity below 10 pascal-seconds before exposure to actinic radiation is provided. The blended resin includes a first base component that is photocurable, and the first base component includes (i) a first siloxane polymer including a plurality of thiol groups and (ii) a second siloxane polymer including a plurality of functional groups with unsaturated carbon-carbon bond. The blended resin also includes a photoinitiator, a second base component that is condensation curable, and a catalyst. The first base component is configured to polymerize into a primary polymer network and the second base component is configured to polymerize into a secondary polymer network. Furthermore, the primary and secondary polymer networks together form an interpenetrating polymer network.
