    摘要： A method for treating permeable plastics and other porous materials to provide solid barriers within the materials that reduce permeability. One method involves migrating a first gas reactant into the material and migrating a second reactant into the material wherein the first and second reactants react at a reaction interface to form a solid reaction product which provides reduced gas permeability for the material. Embodiments are disclosed in which gaseous reactants are migrated from opposite sides of the material to form an internal gas impermeable barrier. Embodiments are also disclosed where the reactants are sequentially migrated into the material to produce gas impermeable barriers. Swelling of the materials prior to treatment with reactants is also disclosed in order to maximize permeation and reactant migration.

    摘要： A method for treating photosensitive, hydrophilic gelatin holograms to reduce swelling when the gelatin is exposed to moisture. Two reactants which are capable of forming solid reaction products are migrated into the interstitial voids within the gelatin to form a filled gelatin which is resistant to both swelling and shrinkage due to moisture variations. Embodiments are disclosed in which the reactants are migrated simultaneously and sequentially into the gelatin. Examples of a first reactant are silane, chloronated silanes (trichlorosilane and tetrachlorosilane, fluorosilane) and a second reactant oxygen, ammonia, water vapor and suitable gaseous sources of oxygen.

    摘要： An Ormosil composite coating that provides good corrosion and abrasion resistance of the underlying substrate. The Ormosil composite coating of the present invention is entrapped with a plurality of inorganic particles of a size greater than 1 micron to produce a coating of a sufficient, desired thickness. The coating of the present invention, generally includes an ormosil composite including a plurality of entrapped inorganic particles wherein each of the plurality of inorganic particles is at least one (1) micron in its maximum dimension but not greater than 75 microns (however, a maximum dimension of 5 microns is preferred).

    摘要： A process for chemical removal of organically-modified silicate (Ormosil) coatings from aluminum alloy substrates without degradation of the underlying metal. An Ormosil film is treated with a zincate solution. The zincate solution dissolves the Ormosil film and deposits a thin, easily-removed layer of zinc onto the aluminum alloy surface, which prevents base-activated dissolution of the underlying metal. The zinc layer may be removed using dilute phosphoric acid, leaving the surface of the aluminum alloy intact. Consequently, the sol-gel coating may be removed while the integrity of the aluminum alloy substrate is maintained.
