  • Patent number: 4350804
    Abstract: The invention is directed to curable compositions comprising an azole-functional resin and a labile metal-ligand complex. The azole-functional resin is the reaction product of a monomeric or polymeric resin and a reactive N-heterocyclic compound containing at least two nuclear nitrogen atoms in a 5-membered ring structure capable of forming stable metal-ligand complexes. Mixtures of azole-functional resins also may be used with the labile-metal ligand complexes in the compositions of the invention.

  • Patent number: 4322459
    Abstract: The invention is directed to resins which are the reaction product of an amino or mercapto substituted azole and a polyepoxide wherein the ratio of equivalents of the azole to the polyepoxide is from about 0.5:1.0 to about 1.5:1.0, preferably from about 0.9:1.0 to about 1.1:1.0. The resins can be acid or base solulized depending on whether amino or mercapto substituted azoles were used in their preparation. The invention is also directed to storage stable compositions which cure at relatively low temperatures in short periods of time comprising specified amounts of the resin containing azole-functionality, polyepoxides, organic solvents, and optionally pigments and additives.

  • Patent number: 4321304
    Abstract: Novel compositions of matter comprising the reaction product of beta-diketones and epoxy resins blended with monomeric or polymeric phosphonium salts are hereby provided. The beta-diketones useful herein are those which enolize in amounts that render them sufficiently acidic and reactable with epoxy groups of the resin. The novel reaction products can be dispersed in water to form pretreatment agents and they can be formulated with curing agents to form coating compositions. Ferrous metals treated with the compositions of this invention exhibit excellent corrosion resistance properties.

  • Patent number: 4321305
    Abstract: Novel compositions of matter comprising a water-dispersible reaction product of beta-diketones and epoxy material are hereby provided. The beta-diketones useful herein are those which enolize in amounts that render them sufficiently acidic and reactable with epoxy groups of the resin. The novel reaction products can be dispersed in water and they can be formulated optionally with curing agents. Ferrous metals treated with the compositions of this invention exhibit excellent corrosion-resistant properties.

  • Patent number: 4120996
    Abstract: A method of providing corrosion resistance to metal surfaces is disclosed. The method of the invention involves treating the metal surfaces with an ascorbic acid (Vitamin C)-containing composition free of beta-diketones and preferably in combination with molybdenum. The invention is particularly effective as a passivating pretreatment for ferrous metal substrates which are to be subsequently topcoated.

  • Patent number: 4030734
    Abstract: A table game has a substantially horizontal playing surface with a supplemental rebounding surface which can be suspended above the horizontal playing surface, or with a plurality of rebounding surfaces two of which are substantially perpendicular to the playing surface and another above the playing surface. The table game is constructed so that at least two players are on opposing sides of the rectangular horizontal playing surface, each player striking the ball so that it is directed to the opposing player. The transparent supplemental rebounding surfaces are preferably constructed of transparent material so that spectators can view the travel of the ball during play.
