Abstract
A method of making a lithium alkylsiliconate composition comprising adding an alkylalkoxysilane to a first mixture comprising lithium hydroxide and water to form a second mixture comprising a lithium alkylsiliconate and an alcohol, wherein i) the mole ratio of lithium hydroxide to alkylalkoxysilane is from 0.9 to less than 1.1 and the water is from 89 to 93 mol %, or ii) the mole ratio of lithium hydroxide to alkylalkoxysilane is from 1.1 to 1.4 and the water is from greater than 93 to 99 mole %.
