摘要: A method of obtaining fine-grained, free-flowing powdered silicone resins is disclosed. The powdered silicone resins contain very low or no residual aromatic solvents or other volatile organic compounds. The method includes the steps of (1) preparing a solution of an MQ silicone resin dissolved in a volatile liquid organosilicon solvent, such as hexamethyldisiloxane, and (2) spray-drying the solution obtained in step (1) to produce the silicone resin powder.
