ABSTRACT:
Disclosed is an ungelled resin comprising a compound corresponding to a specified formula (I) which compound typically is prepared by reaction of an aminoalkyloxy silane with an organic isocyanate. The ungelled resin contains a hydrolyzable group that is attached directly to Silicon. The ungelled resin can be utilized in coating compositions. The ungelled resin can be cured with moisture and/or with polyols, and can be used to provide protective and/or decorative films on a variety of substrates.
The novel compounds contained in the ungelled resin for convenience can be thought of as prepared from an organic isocyanate having an average functionality of at least 1; a silicon-containing compound corresponding to a specified formula (III) infra, the silicon-containing compound having at least one hydrolyzable group; and a compound containing at least 2 carbon atoms, at least 1 functional group reactive with a moiety on the silicon-containing compound and at least one amino group. A compound of the resin contains at least one hydrolyzable group from the silicon-containing compound. A compound of the resin also contains a residue of the silicon-containing compound bonded to a residue of the compound containing at least 2 carbon atoms through an oxygen-silicon linkage.
