Abstract: Methods are disclosed for providing a library of composite or novel composition samples on a support. The method involves depositing one or more components as concentration gradients on the surface of the support. The concentration gradients are placed on the support in the form of superimposed triangles which allow ready formation of composite or composition samples containing three or more components. The samples can be removed from the support by drilling out portions of the coated support so as to yield individual tablets containing the support with one or more component layers thereon. By using this method, a vast number of samples can be made.

Abstract: A laminar pigment which has hydrolyzed silane coupling agent treated surface is used as a pigment for a powder coating composition. By combining the pigment with a powdery film-forming polymer, a film-forming composition, which can be applied by electrostatic coating is produced. With the addition of leveling agent to the silane treated products, the spray properties of effect pigments are improved. The products of this invention are useful in all types of automotive and industrial paint applications.

Abstract: A method for treating an article which involves exposing an article within a space to a concentration of chlorine dioxide gas that exceeds the IDLH, STEL or TLV, then reducing the concentration of chlorine dioxide gas within the space to a positive quantity below the IDLH, STEL or TVL. Thereafter, additional chlorine dioxide gas is introduced into the space, but the concentration within the space remains below the IDLH, STEL or TVL.

Abstract: A massive body, e.g., a tablet, for producing a solution of chlorine dioxide when the massive body is added to liquid water. The massive body comprises a metal chlorite such as sodium chlorite, an acid source such as sodium bisulfate and a source of free halogen such as the sodium salt of dichloroisocyanuric acid or a hydrate thereof. The concentration of free halogen in the solution will be: (a) less than the concentration of chlorine dioxide in said solution on a weight basis and the ratio of the concentration of chlorine dioxide to the sum of the concentrations of chlorine dioxide and chlorite anion in said solution is at least 0.25:1 by weight; or (b) equal to or greater than the concentration of chlorine dioxide in said solution on a weight basis and the ratio of the concentration of chlorine dioxide to the sum of the concentrations of chlorine dioxide and chlorite anion in said solution is at least 0.50:1 by weight.

Abstract: The present invention is generally directed to a method of producing an aqueous solution of chlorine dioxide from the reaction of a metal chlorite and an acid forming component which do not react to produce chlorine dioxide in the substantial absence of water. The reactants are separated from liquid water by a membrane which allows the controlled passage of liquid water and/or water vapor into contact with the reactants. The chlorine dioxide thus generated passes out through the membrane into the liquid water to produce the desired aqueous solution. Aqueous solutions containing chlorine dioxide produced in this manner can be conveniently used for commercial and domestic cleaning operations such as in the food industry.

Abstract: The invention pertains to a device for generating aqueous chlorine dioxide solutions when the device is contacted with liquid water. The device comprises an alkali metal or alkaline earth metal chlorite, e.g., sodium chlorite, and a chemical reagent comprising an acid or a material capable of releasing an acid upon exposure to liquid water, e.g., sodium bisulfate. The chlorite and the reagent are either combined as a mixture or are disposed as separate components adhered to the surface of one or more substrates. Upon exposure to liquid water, the chlorite and the reagent produce boundary layers. The chlorite and the reagent are disposed upon, and adhered to, the surface(s) of the substrates in a manner such that upon exposure to liquid water, the chlorite boundary layer comes into contact with the reagent boundary layer to thereby produce an aqueous chlorine dioxide solution.
