Abstract
The invention provides a process for the production of a pressure sensitive adhesive, comprising dissolving a particulate solid MQ silicone resin having a bulk density in the range 0.4-0.9 g/cmin a volatile solvent, and dissolving a polydiorganosiloxane having a viscosity of 0.1 to 40,000 Pa·s at 25° C. in the volatile solvent before, simultaneously with or after dissolving the solid MQ silicone resin. The process of the present invention allows the production of a pressure sensitive adhesive in a solvent different from the solvent in which the MQ silicone resin was prepared.
