  • Patent number: 6957672
    Abstract: A method suitable for use in small trade stores or retail shops for assisting in providing the correct color or coating compositions mixed in the store or shop in which colorants (II) are added to a base paint (2), the base paint (2) being provided in a lidded container (I). The base paint (2) is pre dispensed in a lidded container (I), thereby avoiding the need to weigh it accurately in store thus saving time. Further time is saved by adding the colorants simultaneously to the base paint (2). The actual load (usually the combined weight of the can and the contents) is compared to the correct load stored in a database and the operator is alerted if the two fail to match.

  • Patent number: 6903157
    Abstract: A thickened aqueous coating composition (preferably paints and the like or adhesives) containing a film-forming polymeric binder which produces dried coatings having less sensitivity to water by using a thickener which is autoxidisable. Preferred autoxidisable moieties are provided by derivatives of long chain fatty acids of the type used in alkyd paints and association is the preferred thickener mechanism. The moieties may form part of a compound which can take part in a copolymerisation to form a polymeric backbone for the thickener and if the compound is not very soluble in water, the copolymerisation mixture is subjected to intensive agitation to form droplets of less than 500 nm which compensates for the lack of solubility. The thickener may serve as its own binder if sufficient amounts are used.

  • Patent number: 6740705
    Abstract: A process for making poly(urethane-urea)/addition polymer composite particles which avoids the need to use a highly viscous solution of a prepolymer for the poly(urethane-urea). The process comprises dissolving diol and di-isocyanate in addition polymerisable monomers and allowing them to co-react but for only long enough to form a precursor for the prepolymer which is of a lower molecular weight than the prepolymer so that the precursor forms a solution of much lower viscosity. This lower viscosity solution is then dispersed in water to give droplets in which the co-reaction continues and completes the formation of the prepolymer whilst water diffuses into the droplets and causes chain extension to create the poly(urethane-urea) particles.

Preferred autoxidizable moieties are provided by long chain fatty acids of the type used in alkyd paints and association is the preferred thickener mechanism. The moieties may form part of a compound which can take part in a copolymerization to form a cellulose-free polymeric backbone for the thickener and if the compound is not very soluble in water, the copolymerization mixture is subjected to intensive agitation to form droplets of less than 500 nm number average diameter which compensates for the lack of solubility. The thickener may serve as a binder if sufficient amounts are used.

  • Patent number: 6646085
    Abstract: An ambient dry water dispersed coating composition substantially free of volatile organic coalescing solvents, the coating composition containing a polymer film forming binder comprises between 40% and 50% copolymerized non-conjugated, unsaturated fatty acid triglyceride, between 40% and 55% copolymerized ethylenic monomer including styrene, and between 3% and 12% copolymerized maleic anhydride. The film forming copolymer is produced by first reacting maleic anhydride with the fatty acid triglyceride at high temperatures between 140° C. to form a maleinized triglyceride having a pendent maleic anhydride structure. The maleinized triglyceride is then styrenated at temperatures between about 80° C. and 200° C. in the presence of at least 4% peroxide initiator based on the weight of monomers copolymerized to form a styrenated, maleinized fatty acid triglyceride copolymer having anhydride groups.

  • Patent number: 6627265
    Abstract: The present invention is directed to a method of and apparatus for forming a coating having at least one fade zone over a substrate. The method and apparatus include positioning a coating composition dispenser above a surface of a substrate with the coating composition dispenser oriented to dispense a coating composition spray generally normal to the surface of the substrate. A gas dispenser is also positioned above the surface of the substrate and adjacent the coating composition dispenser with the gas dispenser oriented to dispense a gas stream generally normal to the surface of the substrate. The coating composition spray and the gas stream are spaced from each other so as to develop an interference effect therebetween adjacent the surface of the substrate. Preferably the substrate is maintained at a temperature which pyrolyzes the coating composition. The interference effect directs the coating composition to deposit over the substrate as a coating having a fade zone.

  • Patent number: 6623794
    Abstract: A heat processable coated article suitable for tempering and/or bending which has metallic properties is prepared by coating a glass substrate. The substrate has deposited over it a stabilizing film and a metal-containing film is deposited over the stabilizing film. Also an overcoating with a protective layer of a silicon compound is deposited over the metal-containing film and forms a durable layer and prevents oxidation of the underlying metal-containing film. The coated article can be tempered and/or bent without losing its metallic properties to oxidation.

  • Patent number: 6620880
    Abstract: An environmentally friendly stable aqueous optionally structured water-resistant architectural coating composition (especially a paint) containing a film-forming binder polymer composed of a starch modified by the presence of carboxylic acid or inorganic carboxylate groups and bonded (probably grafted) to chains of copolymerized mono-ethylenically unsaturated monomers (e.g. “acrylic”, “vinyl” or “styrenic” copolymers) permitting a stable aqueous dispersion of the binder polymer to be made which retains good water-resistance in the dried paint. The modified starch allows paints to be made with less dependence on materials obtained from non-renewable resources whilst retaining a low water-sensitivity.

  • Patent number: 6605555
    Abstract: Glass is made from batch components having a source of ferrous iron to increase the starting amount of ferrous iron in the glass batch. The ferrous iron source is an iron silicate material, such as fayalite (2FeO.SiO2), iron garnet (3FeO.Fe2O3.3SiO2) magnesium-iron olivine (2(Mg,Fe)O.SiO2), grunerite (6FeO.8SiO2FeOH)2, actinolite (CaO.3(Mg,Fe)O.4SiO2) or iron rich anthophyllite ((Mg,Fe)O.SiO2). The presence of the ferrous iron source in the glass batch components decreases or eliminates the amount of coal and also leads to a glass article having a redox ratio greater than about 0.25.
