    Abstract: Cured coatings having a high degree of extensibility and other desirable properties are obtained from compositions comprising a hydroxyl-containing, urethane reaction product containing a polyether component and an amine-aldehyde resin. Preferred compositions contain a polyether polyol of low glass transition temperature. These compositions are storage-stable in one package, and the cured coatings are adherent, durable and highly extensible. These coatings are particularly useful on resilient and rubbery substrates, such as foam rubber, polyurethane foam and vinyl foam, and on soft metal surfaces such as mild steel and aluminum.

    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.
