ABSTRACT:
The present invention relates to methods for diluting water-stable organosilane compositions comprising an organosilane, optionally having a non-hydrolyzable organic group, but having one or more hydrolyzable groups, and an acidified stabilizing solution prepared from at least one acid, and at least one cationic surfactant, preferably at least one quaternary ammonium salt (QAS), in water. The organosilane composition is diluted with a glycol ether. The resultant diluted organosilane composition may be used to antimicrobially treat a substrate.
