  • Adhesives and sealants containing adhesion promoter comprising waste powder prime
    Patent number: 6162504
    Abstract: Waste powder prime comprising from about 30 to about 70 weight percent epoxy resin, the balance of the waste powder prime comprising filler, pigment and/or curing agent, is advantageously employed as a replacement for epoxy resins in conventional adhesion promoter systems for polymeric plastisols. The resulting compositions are useful as adhesives and sealants in industrial manufacturing processes such as in the manufacture of automobiles.

  • Amine-functional monoethylenic monomers, acrylic copolymers and aqueous coating compositions containing the same
    Patent number: 4713481
    Abstract: Monoethylenically unsaturated polymerizable monomers carrying a plurality of ketimine-blocked primary amine groups are disclosed. These are preferably provided by reacting an organic diisocyanate with the single secondary amine group of a ketimine-blocked diprimary amine carrying a single secondary amino hydrogen atom and then reacting a monohydric acrylate with the other isocyanate group. These monomers are polymerizable to provide copolymers with other monoethylenically unsaturated monomers, and especially acrylate-functional monomers, in which the amine groups remain blocked. These amine groups become unblocked when the copolymers are dispersed in water to form various types of aqueous coating compositions.
