Abstract
Disclosed are moisture-curable compositions based on (A) ungelled, partial hydrolyzates or organosilicon-containing materials in combination with (B) acrylic addition interpolymers containing hydrolyzable silyl groups. The organosilicon-containing material for preparation of the ungelled partial hydrolysis product has an average functionality based on easily hydrolyzable Y groups attached to silicon atoms of greater than or equal to 2.4 and contains greater than or equal to 10 mole percent of at least one organosilane compound corresponding to the formula R-Si-Y.sub.3. The partial hydrolysis product is prepared using a controlled amount of water. The acrylic addition interpolymer is not particularly limited provided that it contains at least one silicon atom directly bonded to a hydrolyzable group and is compatible with the ungelled partial hydrolysis product.
