摘要:
A method of inverting the phase arrangement of the silicone phase and the acrylic phase in a silicone acrylic hybrid composition, the silicone acrylic hybrid composition comprising: a) a silicone acrylic hybrid pressure sensitive adhesive, and b) a solvent, wherein the phase arrangement of the silicone phase and the acrylic phase in the initial silicone acrylic hybrid composition forming a continuous external phase and a discontinuous internal phase is determined by the solvent, comprising the step of adding an activator to the silicone acrylic hybrid composition, wherein the activator a) is liquid at 20° C. and 1013 mbar, b) has a boiling point which is higher than the boiling point of the solvent and/or has a vapor pressure at 20° C. which is lower than the vapor pressure of the solvent contained in the silicone acrylic hybrid composition, and c) provides better dissolution properties for the inner phase of the initial silicone acrylic hybrid composition than the solvent contained in the silicone acrylic hybrid composition.
