PROCESS FOR PRODUCING SILOXANE-CONTAINING RELEASE COATINGS

Abstract

The invention provides a process for producing siloxane-containing release coatings which comprises curing a siloxane-containing coating material by irradiation with microwaves.

Description

Claims

1. A process for producing siloxane-containing release coatings by curing a siloxane-containing coating material by irradiation with microwaves.

2. A process as claimed in claim 1, wherein the siloxane-containing coating materials comprise one or more thermosetting compounds.

3. The process as claimed in claim 2, wherein the siloxane-containing coating materials comprise one or more compounds selected from the group consisting of vinyl-functional siloxanes and siloxanes containing SiH groups.

4. A process as claimed in claim 1, wherein the siloxane-containing coating materials comprise one or more free-radically curing compounds.

5. A process as claimed in claim 4, wherein the siloxane-containing coating materials comprise one or more (meth)acrylate-functional siloxanes.

6. A process as claimed in claim 1, wherein the siloxane-containing coating materials comprise one or more cationically curing compounds.

7. A process as claimed in claim 6, wherein the siloxane-containing coating materials comprise one or more epoxy-functional siloxanes.

8. The process as claimed in claim 1, wherein the coating materials comprise one or more organic and/or one or more inorganic particles having polar surfaces.

9. The process as claimed in claim 8, wherein silica is used as particles.

10. The process as claimed in claim 1, wherein the coating materials comprise one or more ionic compounds.

11. The process as claimed in claim 10, wherein ionic liquids are used as ionic compounds.

12. The process as claimed in claim 10, wherein ionically modified siloxanes are used as ionic compounds.

13. The process as claimed in claim 12, wherein quaternary ammonium-modified siloxanes are used as ionic compounds.
