  • Coating composition containing a low VOC-producing silane
    Publication number: 20060205907
    Abstract: A coating composition is provided which includes an adhesion promoter or a crosslinker silane which, upon hydrolysis, of its hydrolyzable sites, produces a reduced amount of volatile organic compound compared to that produced by the hydrolysis of a silane possessing an equivalent number of hydrolyzable sites all of which are hydrolyzable alkoxy groups.
