Abstract
A process for producing a low VOC epoxy silane oligomer which includes hydrolyzing an epoxy silane, the epoxy silane upon hydrolysis of its hydrolyzable sites producing 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, the hydrolyzing of the epoxy silane being carried out with less than 1.5 equivalents of water, said water being continuously fed during the hydrolysis reaction.
