    摘要: A coating composition for application to primed metal substrates as a topcoat is disclosed. The coating composition is especially useful on metal closures for vacuum-packed food products. The coating composition is free of a halide-containing vinyl-polymer and comprises: (a) an acrylate co-polymer having pendant hydroxy groups, (b) a hydroxy-terminated polyester, (c) a crosslinker, and (d) a nonaqueous carrier.

    摘要: Thermosetting polyurethane compositions comprising a polymer having a molecular weight of from 500 to 10,000 and containing from about 0.3 to about 15 percent by weight of one or more functional groups selected from the group consisting of --OH, --COOH, --CONH.sub.2 and ##STR1## and a mixture of monomeric and oligomeric polyfunctional substituted urethane compounds, which may be derived by reaction of a polyol and isocyanic acid, followed by methylolation and alkylation. Such compositions may be cured at elevated temperatures to produce solvent-resistant coatings.

    摘要: A cathodically electrodepositable, self-cross-linkable polymer is a hydroxyalkyl carbamate-containing resin having at least one tertiary amine and at least two hydroxyalkyl carbamate groups per molecule. The polymer is made by reacting an epoxy resin having an average epoxy equivalent weight of from about 300 to about 10,000 with one or more amines having at least one secondary amine group and at least one hydroxyalkyl carbamate group or precursor thereof. Hydrophobic amines may be co-reacted to enhance hydrophobicity of the polymer. An electrodeposition bath is made by acidifying the polymer to form an aqueous dispersion. A low temperature-curable coating is attained by utilization of the polymer with a suitable quaternary or ternary compound catalyst.
