Abstract
An aqueous emulsion of alkylalkoxysilane which has a stable emulsion state for a long period of time and is useful as an infiltrative preventer of water absorption into a porous inorganic construction material, the emulsion containing an alkylalkoxysilane, water and an emulsifier, wherein droplets of the alkylalkoxysilane in the water has a diameter in the range of from 0.5 to 10 .mu.m, and a process for the production of an aqueous alkylalkoxysilane emulsion, which comprises emulsifying and dispersing an alkylalkoxysilane, water and an emulsifier under conditions sufficient to form an emulsion in which droplets of the alkylalkoxysilane in the water has a diameter in the range of from 0.5 to 10 .mu.m.
