Abstract
The present invention encompasses materials and methods for catalyzing the cross-linking and curing of siloxane polymers. In particular, the present disclosure provides materials, methods, and conditions for vapor phase catalysis for curing organosiloxane polymers and resins, including resin linear organosiloxane block copolymers, as well as the incorporation of those methods into processes for making light emitting devices, including light emitting diodes.

A method comprising:
- contacting a solid viscoelastic film with a first catalyst that is in a vapor phase, the solid viscoelastic film comprising an uncured polymer;
- and
- curing the uncured polymer after the solid viscoelastic film is contacted with the first catalyst to provide a cured polymer,
- laminating the solid viscoelastic film over a light emitting device.
