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.
Claims17
A method comprising:
- contacting a first material with a first catalyst that is in a vapor phase, the first material comprising an uncured polymer, a second catalyst, and a particle that inhibits the second catalyst;
- and
- curing the uncured polymer after the first material is contacted with the first catalyst to provide a cured polymer.
A method comprising:
- providing a first material comprising an uncured polymer and a particle that is at least one of light-scattering particle and a rheological additive, the particle arranged to accelerate a rate of curing of the uncured polymer;
- contacting the first material with a first catalyst that is in a vapor phase;
- and
- curing the uncured polymer after the first material is contacted with the first catalyst to provide a cured polymer.

A method comprising:
- providing a first material comprising an uncured polymer,
- curing the uncured polymer to provide a cured polymer;
- and
- after providing the cured polymer, contacting the cured polymer with a vapor phase material to retard or stop crosslinking of the cured polymer.
