摘要:
An aqueous emulsion, having a long shelf life, of a low molecular weight silicone resin comprising by weight(a) 1-60% of a silicone resin of the formula ##EQU1## wherein R.sup.1 is a monovalent hydrocarbon radical having 1 -14C atoms,R.sup.2 is a monovalent hydrocarbon radical having 1 -18C atoms,x has a value from about 0.75 to 1.5 andy has a value from about 0.2 to 2.0,and having a viscosity of about 2 to 2000 mPa.s,(b) 0.1-10% of an emulsifier, and(c) water.Advantageously two non-ionic emulsifiers are used in combination.
