  • Patent number: 12049576
    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.
