| 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/cm 3 in 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. |
