Metallic acrylate curing agents and usage thereof in intermediate compositions
View Patent ↗The disclosure relates to using metallic acrylate compounds such as zinc diacrylate (ZDA), zinc dimethacrylate (ZDMA), among others for curing epoxy functional (and other cross-linking compounds), and to compositions containing such compounds for use in powder coat, film, adhesive, among other applications. ZDA and ZDMA containing compounds can also be supplied as an intermediate product that can cure the epoxy component of the compositions while being substantially free of conventional curing agents.
1. An intermediate composition comprising at least one member selected from the group consisting of epoxies, epoxy functional materials, acrylates, methacrylates, acrylate functional materials, methacrylate functional materials, oils, thermoplastics, elastomers, rubbers, plasticizers, melamine, isocyanurates, polysiloxane, alkyds, phenolic modified alkyds, acrylic alkyd copolymers, polyesters, epoxy esters, polybutadienes, phenoxy and epoxy/analkoamine polymer blends; and about 5 to about 20 weight percent of at least one curing agent which is sufficient to cure said at least one intermediate composition selected from the group consisting of metallic acrylates, metallic diacrylates, metallic dimethacrylates and metallic monomethacrylates wherein the composition is substantially free of peroxides, amines, polyamides, dicyandiamide, polysulfides, anhydrides, melamines, ureas and substituted ureas, anhydrides, imidizole and imidizole compounds, boron trifluoride and complexes, amidoamines, and phenol/formaldehydes.
2. The composition of claim 1 further comprising at least one carrier.
3. The composition of claim 1 wherein said member comprises at least one epoxy functional compound.
4. The composition of claim 1 wherein the compound comprises at least one member selected from the group consisting of polybutadiene, melamine, isocyanates, bis A epoxy, bis F epoxy, cycloaliphatic epoxy, novolac compounds, epoxy esters, alkyds and alkyd functional materials, polyesters and acrylates.
5. The composition of claim 1 wherein the metallic acrylate curing agent comprises at least one of zinc diacrylate, zinc dimethacrylate, zinc acrylates, zinc monomethacrylates, and zinc hydroxyl functional monomethacrylates.
