  • Publication number: 20060234889
    Abstract: A method for stripping a floor using a concentrate prepared by mixing a substantially nonchlorinated concentrate containing a floor finish solvent and an at least partially unactivated water thickener. The concentrate is diluted merely with water at an intended use location to activate the water thickener and noticeably increase within ten minutes or less the viscosity of the resulting mixture, then applied to a hardened floor finish atop a floor and allowed to soften or dissolve the floor finish so that the finish may be removed from the floor.

  • Publication number: 20060234890
    Abstract: Floor finishes can be stripped using a substantially nonchlorinated concentrate comprising a floor finish dissolver and an at least partially water-unactivated water thickener. The concentrate is diluted with water at an intended use location to activate the water thickener and noticeably increase within sixty minutes or less the viscosity of the resulting mixture, then applied to a hardened floor finish atop a floor and allowed to soften or dissolve the floor finish so that the finish may be removed from the floor.

  • Patent number: 7067182
    Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricating coating that is thermally cured at less than 200° C. or radiation-cured. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping, renewable lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide dry lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

  • Patent number: 7018561
    Abstract: The present invention provides a beverage surfactant composition that includes a surfactant, a phosphonium compound, and a carrier; wherein the beverage surfactant composition exhibits stability as a solution or as a dispersion at a temperature of about 0° C. to about 8° C. The present invention also provides a container or a conveyor for a container having a surface that is at least partially coated with the composition. The present invention also provides a process for lubricating a container that includes contacting at least a portion of a surface of the container and the composition together. The present invention also provides a process for lubricating a conveyor that includes contacting at least a portion of a surface of the conveyor and the composition together. The present invention also provides a method for enhancing stability as a solution or a dispersion of a composition containing a surfactant and a carrier, involving incorporating a phosphonium compound into the composition.

  • Publication number: 20050277556
    Abstract: A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.

  • Publication number: 20050153139
    Abstract: Zinc crosslinked acrylic dispersions can initiate hardening of 2K polyurethane coatings based on polyester polyols or polyurethane polyols and decrease the coating tack-free time. The decreased tack-free times facilitate earlier application of additional polyurethane layers and earlier return of a coated article to service, and can provide improved floor finishes.

  • Publication number: 20050153140
    Abstract: A jobsite-renewable multilayer floor finish system has an undercoat employing a first hardening system, an autohardenable (e.g., two-part) topcoat employing a second hardening system, and at least one initiator for the topcoat hardening system in at least the undercoat. The initiator increases the topcoat hardening rate while reducing the topcoat pot life to a lesser extent than would be the case if the initiator were included only in the topcoat. The increased topcoat hardening rate facilitates earlier application of additional topcoat layers, or earlier return of the floor to service.
