Abstract:
A method is disclosed for producing a pigment coating on a substrate. A hardenable polymer coating is initially provided on the substrate, followed by an excess of hardening agent. This produces a first hardened coating with sufficient hardening agent remaining to harden a second polymer coating, containing suspended pigment, which is deposited on top of the first coating. The polymer is then pyrolyzed, leaving a coating of pigment on the substrate.
Abstract:
A dispersion, suitable for finishing substrates such as wood, metal, leather, paper, fabrics, plastics and the like, having a continuous liquid phase and a dispersed polymer phase which undergoes only partial coalescence on drying under ambient conditions thereby being easy to work (sand). On being subjected to coalescing means substantially complete coalescence can thereafter be obtained.
Abstract:
Coating apparatus suitable for depositing superimposed layers of two different viscous liquids or pastes on a support is provided which comprises a pair of hoppers having one lip common to both hoppers, forming the downstream lip of the upstream hopper and the upstream lip of the downstream hopper.
Abstract:
The present application discloses a method of forming a hydrogel-coated substrate, wherein the hydrogel has antifouling and antimicrobial properties. The method comprises applying an aqueous pre-hydrogel solution to a substrate, polymerizing the aqueous pre-hydrogel solution, thereby forming a coated substrate having a conformal hydrogel coating and a non-conformal hydrogel coating, contacting the coated substrate with a swelling agent, and removing the non-conformal hydrogel coating from the coated substrate, thereby leaving the conformal hydrogel coating on the substrate to form the hydrogel-coated substrate. The aqueous pre-hydrogel solution comprises a monomer with antimicrobial activity, a monomer with antifouling activity, and either a polymer, oligomer, or macromer which, when polymerized together, form a hydrogel. Also disclosed is a coated substrate and a hydrogel coating.
Abstract:
A cure promoter composition is disclosed, including an accelerator which may include a thiocarbamate, a hydrated thiocarbamate, a dithiocarbamate, a thiazole, a mercaptothiazole, a sulfenamide, a thiazolesulfenamide, a metal salt of thiocarbamate, sulfur chloride, or combinations thereof. The cure promoter composition also includes a compatibilizing carrier, one or more organic solvents, a catalyst, an optional reducing agent, an optional reactive silane, an optional reactive organometallic, an optional gelling agent, and an optional aqueous component. A method for applying the cure promoter composition is disclosed, including contacting the organic solvents, the accelerator, the carrier, the reactive silanes, the reactive organometallics, the reducing agents, and the catalyst with one another to prepare the cure promoter composition, homogenizing the cure promoter composition, pausing after homogenizing to allow the cure promoter time to react, applying a sealant onto a substrate, and applying the cure promoter composition to a surface of the sealant.
Abstract:
Improved aluminum can end stock (CES) is disclosed. The CES includes an adhered polymer coating exhibiting low feathering and high performance in various acid tests. The low feathering and resistance to acid tests is accomplished by incorporating a copolymer adhesion promoter film to an aluminum alloy before lamination. In some cases, the metal strip is pretreated with a conversion layer, which can include compounds of trivalent chromium (Cr(III)) and phosphates or titanium and zirconium.
Abstract:
Methods for encasing bodies including smokeless tobacco or a tobacco substitute with a polymeric casing can include coating a compressed body with microfibers, applying tubular casings to compressed bodies, printing netting and webs on compressed bodies, injection molding around compressed bodies, applying a webbing to compressed bodies, placing compressed bodies into a skin forming bath, and including thermoplastic polymers in a compressed body.
Abstract:
A drying method of a polyimide paste which can maintain a printing shape while maintaining productivity includes an organic solvent and a polyimide resin dissolved in the organic solvent, and which becomes cured polyimide by being cured as a result of being dried and heated, the drying method including a step of applying the polyimide paste to a surface of a base material, a step of applying a solvent including a polar material to a surface of the base material at least at a portion where the polyimide paste is applied, and a step of, after applying the solvent including the polar material, drying the polyimide paste and the solvent including the polar material.
