ABSTRACT:
Disclosed is an ungelled acrylic resin composition containing an acrylic polymer having in a molecule thereof at least one group containing a silicon atom selected from: ##STR1## wherein each R independently is selected from the group of moieties consisting of Y, hydrogen, a C.sub.1 -C.sub.10 group joined to Si through an Si--C linkage, and OR.sup.7 in which R.sup.7 represents alkyl having at least 4 carbon atoms, aryl, alkylaryl, arylaklyl, aryloxyalkyl, or alkyloxyalkyl, wherein Y represents an easily hydrolyzable group.
The acrylic resin composition, contains an amount of easily hydrolyzable Y moieties such that the ratio of the number of grams of the ungelled acrylic resin composition to equivalent of easily hydrolyzable Y moieties in the ungelled acrylic resin composition is in a range of from 40 to 667. Prefered acrylic resin compositions of the invention can be cured in the presence of atmospheric moisture and a suitable catalyst at a temperature of less than or equal to 121 degrees Celsius within 3 hours.
Disclosed is a method for producing the ungelled acrylic resin composition.
Also disclosed is a nonaqueous composition, particularly a nonaqueous coating composition, containing the ungelled acrylic resin composition. Preferred coating compositions containing an ungelled acrylic resin composition can be cured in the presence of atmospheric moisture and a suitable catalyst at a temperature of less than or equal to 121 degrees C within 3 hours.
