Abstract
This invention is a silica free curable composition comprising PA1 A) A stable dispersion in an aqueous medium of a First Polymer having a weight average molecular weight of at least 50,000 which is insoluble in water and contains silane groups with hydrolyzable functionality. PA1 B) A solution or dispersion in the aqueous medium of a second polymer which has a number average molecular weight between 1,000 and 20,000 and at least two silane groups with hydrolyzable functionality. The non-volatile weight ratio of the first polymer to the second is 40:1 to 1:4.
