Abstract
Novel and highly reactive hydrolyzed silane emulsions are achieved by emulsifying a hydrolyzable alkoxysilane (e.g., or the like) in water in the presence of an effective amount of an emulsifier of sufficiently high HLB value (preferably 14 or greater) to simultaneously retain said hydrolyzable alkoxysilane compound in a substantially totally hydrolyzed state and inhibit said resulting hydrolyzed alkoxysilane compound from self-condensation. Such reactive emulsions containing hydrocarbon silanes are useful to produce durable coatings that impart water repellency and lubricity to substrates having siliceous, cellulosic or proteinaceous surfaces.
