Abstract: Provided is a radiation curable silicone composition suitable for additive manufacturing processes, a process for making such compositions, and a method for forming an article from such compositions. The compositions exhibit fast radiation curing over a variety of wavelengths. The articles formed from the compositions exhibit a good balance of properties including flexibility and mechanical strength. In embodiments, the organo-silicone composition comprises at least one polymerization-effective silicone containing polymer bearing unsaturated hydrocarbon group, at least one mercapto functional silicone resin, and a photo initiator.

Abstract: A process for producing a silicone pressure sensitive adhesive is shown and described herein. The process comprises reacting a MQ silicone resin with a polydiorganosiloxane in the absence of a solvent. The MQ silicone resin is a solid, solventless MQ resin. The reaction may be conducted in the presence of a catalyst, a chain extension reagent, or a combination thereof, and the resulting pressure sensitive adhesive can be dissolved in a solvent and the solids content adjusted. The present method provides a manner to provide a cleaner adhesive material that is free of unwanted materials such as aromatic solvents and also substantially free of cyclic siloxane impurities.
