Abstract: Aqueous metal ammine siliconate solutions are the reaction products of selected metals or metal derivatives, selected mono-organosilicon materials, certain alkaline nitrogen compounds having the formula R--NH.sub.2, and water. Amorphous materials are formed when volatiles are removed from the siliconate solutions. The metal components in the resulting amorphous materials are not readily leached out by normal weathering, washing or the like. The solutions are useful in a method for treating substrates, such as wood, textiles, thread, canvas, carpeting, paper and masonry, to confer antimicrobial properties. The organosilicon component can be selected so that such treatments also confer either hydrophobic or hydrophilic properties to the substrates. The components of the solutions can be selected to enhance their ability to form continuous films of amorphous materials when used in such treatments, making the solutions useful to provide antimicrobial coatings which may be either hydrophobic or hydrophilic.
