    • The present invention relates to a silicone rubber microsuspension which has an excellent high-concentration storage stability, and to a method for the preparation of a silicone rubber microsuspension. The silicone rubber microsuspension comprises a microparticulate silicone rubber having an average particle diameter not exceeding 10 micrometers, a nonionic surfactant whose HLB value is less than 10, a nonionic surfactant whose HLB value is at least 10, and water, with the proviso that the content of the microparticulate silicone rubber in the silicone rubber microsuspension is at least 50 weight percent. The method for the preparation of said silicone rubber microsuspension comprises mixing a liquid silicone rubber composition, a nonionic surfactant having an HLB value of less than 10, a nonionic surfactant having an HLB value of at least 10, and water.
