  • Patent number: 7674760
    Abstract: Floor finishes are stripped or deep scrubbed using a floor stripper/cleaner composition containing sparingly water-soluble floor finish solvent; water; sulfonic acid, sulfate acid, phosphonic acid, phosphate acid or aromatic acid coupler in an amount sufficient to provide a homogenous aqueous liquid phase and no or low foaming during shaking; and sufficient organic amine so that the composition pH is about 2 to about 11.

  • Patent number: 7655718
    Abstract: Zinc carbonates such as carbonic acid zinc salt, zinc carbonate hydroxide monohydrate, zinc bicarbonate, zinc tetraamine carbonate, zinc ammonium carbonate, carbamic acid zinc salt and zinc carbamate can initiate hardening of polyurethane coatings 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.

  • Patent number: 7588645
    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: 7527861
    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.

  • Publication number: 20090017243
    Abstract: Thermally formed thermoplastic articles can be protected from stress cracking in the presence of stress cracking promoting compounds by forming a shaped article comprising a thermoplastic and a liquid hydrocarbon oil composition. We have found that the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymeric structure of the stressed container to prevent or inhibit stress cracking in such materials. The methods and compositions of the invention are particularly useful in preventing stress cracking in polyethylene terephthalate beverage containers during bottling operations during which the bottle is contacted with aqueous and non-aqueous materials such as cleaners and lubricants that can interact with the polyester to cause stress cracking particularly in the container base.

  • Patent number: 7371711
    Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.
