Abstract

Methods of applications of organosilanes optionally having a nonhydrolyzable organic group, but having one or more hydrolyzable groups, with a polyol containing at least three hydroxy groups, where any two of the hydroxy groups are separated by at least three intervening atoms by aerosolization of droplets between 0.5-8 microns are disclosed and an improved formulation comprising adding a nonionic wetting agent are disclosed. An improved aerosolization application technique and the improved formulation provide for smaller droplet size and better coverage of substrates to which the organosilanes are applied. The improved formulation has increased affinity, reduces surface tension and therefore can covalently bond more quickly. A method of treating a substrate, and the treated substrate so formed, by contacting the substrate with the improved formulation for a period of time sufficient for treatment of the substrate are disclosed.
