Abstract of the Disclosure A process for producing a silicone resin comprised of trifunctional and difunctional units comprising partially hydrolyzing and alkoxylating an organohalosilane mixture with an alcohol and waxer such that the aloxylated product con- tains from 5 to 40% by weight of alkoxy groups: adding additional alcohol to the alkoxylated product and removing acid by distillation procedures: adjusting the acidity of the alkoxylated organohalosiloxane intermediate such that it con- tains 1 to 300 parts per million of acid: adding additional water and alcohol so as to hydrolyze the alkoxylated organo- halosiloxane and adjusting the resulting hydroyzate which is the desired silicone resin to the desired solids content.
