Abstract
The present invention relates to a liquid hydrosilicone resin and a preparation process thereof. The average composition of the liquid hydrosilicone resin is represented by the following formula:(RRRSiO).(RRSiO). (RSiO).(SiO) wherein Rto Rare identical or different radicals independently selected from the group consisting of organic groups and a hydrogen atom, with the proviso that at least one of Rto Ris a hydrogen atom bonded directly to a silicon atom. The liquid hydrosilicone resin is obtained by dispersing a hydrosilicone oil, a hydroxyl silicone resin and a dehydrogenation catalyst in a solvent to form a dispersion, allowing the dispersion to react, and then removing the solvent and the catalyst.
