Abstract:
This invention provides a masking material that can be used to protect an underling surface (e.g. an automobile surface) during an overcoating (e.g. painting) operation. The masking material in one embodiment includes a thickener and a pH control agent and water. The masking material can be applied to a surface that is to be protected from paint overspray or other coating processes, allowed to dry, and the surface then coated (e.g. with paint). After drying of the paint, or other coating, the masking material can removed by water washing.
Abstract:
The invention relates to a method for coating or decoating a component, in particular a gas turbine component, wherein, in order to regionally or partially coat or decoat a component, the component is preferably completely covered with a covering medium, and wherein the covering medium is removed from only those surface regions of the component in which the coating or decoating of the component is supposed to take place, so that a surface region of the component which is not to be coated or decoated is covered by the covering medium. According to the invention, the covering medium is removed by means of water jet machining.
Abstract:
The present invention is a method for making a roll cover and a roll cover, wherein at least one material is applied to the surface of the roll or a base substrate. In a first embodiment, a single material is applied as a flowable phase. A uniform coating of the material is applied to the roll, and upon setting of the material, such as by cooling, curing, or other means, a smooth and permanent roll cover is formed upon the surface of the roll. In another embodiment, at least two materials are applied in flowable phases to the surface of the roll. The first material may be a sacrificial, removable first material, applied to the surface of the roll cover in a preselected pattern. After the sacrificial material has been applied, a second material, such as a functional resin, is applied to the surface of the roll cover with the sacrificial material removed after the second material has set. In another embodiment, the use of sacrificial material is avoided and the material is applied in a predetermined pattern. In a fourth embodiment, two or more different materials are applied.
Abstract:
An apparatus for applying a tire dressing fluid to a tire surface is provided. The apparatus includes a tire engagement arm having an applicator manifold and leveling pad. The applicator manifold has an opening for receiving a tire dressing fluid and a plurality of openings for dispensing the tire dressing fluid directly onto the tire surface. The leveling pad is provided for engaging the tire surface and spreading the tire dressing fluid over the tire surface. A method for applying a tire dressing fluid onto a tire surface is provided.
Abstract:
Multilayer film comprising a surface layer and at least one other layer under the said surface layer, each of the said surface layers and of the other layers comprising at least one organic polymer and being free of complexing agents, chelating agents and, optionally, mineral fillers, and the said surface layer also comprising at least one agent capable of promoting the removal of the said surface layer by a rinsing liquid. Process for preparing this film. Surface layered with this film and substrate comprising this surface. Process for protecting a surface against contaminants or pollutants using the said film and process for cleaning or decontaminating a surface similarly using the said film. The invention applies in particular to the protection of surfaces such as walls, facades and road signs against graffiti.
Abstract:
A composition and process are provided to provide a protective sacrificial film on a substrate. The sacrificial protective film collects environmental contaminants and is removed by application of a solution having a pH greater than 9.0. The protective film is formed by coating the substrate with a polymer having acidic moieties that have been neutralized with a base. A contaminated protective film is readily dissolved by a reapplication of an aqueous dispersion containing the neutralized coating polymer.
Abstract:
The present invention provides a method of temporarily protecting a surface which includes the steps of applying a continuous coating of a masking material to said surface, which masking material comprises, before drying, an aqueous solution or emulsion consisting essentially of a film-forming, carboxylic acid-containing polymer; coating all or a portion of said surface with a coating compound, said masking material preventing said coating compound from contacting said surface; and, thereafter, removing said masking material from said surface. Preferably said carboxylic acid-containing polymer is an acrylic or methacrylic acid-containing copolymer and is the sole film-forming component of the aqueous solution or emulsion.
Abstract:
A combination of (A) a nitrogen containing water soluble polymer, (B) a water insoluble film forming polymer, and (C) gas filled, polymer walled microballoons provides a superior thermally releasable coating that (i) can be conveniently and reliably coated from a water based solution and dispersion onto surfaces to be protected against painting, (ii) is reliably stable at ambient temperatures, (iii) even after being coated with many times its own thickness of accumulated paint particles, rapidly disintegrates, along with the accumulated paint coating formed on it, upon contact with hot water, into particles of a size that readily escapes from standard paint booth grate structures, (iv) detackifies any paint particles that escape during distintegration of the combined thermally releasable coating and paint residues accumulated thereon, and (v) disintegrates into particles that float on water, so that they can be readily removed from the grates by immersing the latter in hot water, allowing a few minutes for the disintegration to take effect, and then skimming off the floating solids on the surface of the water.
Abstract:
Solvent free liquid masking compositions comprise from about 5 to about 20 percent by weight of an aliphatic polyol; from about 5 to about 20 percent by weight of a plasticizer; from about 0.1 to about 1 percent by weight of a surfactant; and sufficient water to total 100 percent by weight. A method for protecting selected surfaces from paint in painting operations comprises applying a solvent free liquid masking composition to selected surfaces of an object where paint subsequently applied is not desired; allowing the liquid masking composition to dry, forming a film; painting the object, whereby surfaces carrying the film are protected from the application of paint; and removing the film.
Abstract:
A vehicle masking material and method of use. The masking material in one embodiment includes polyvinyl alcohol, ethyl alcohol, glycerine or triethylene glycol, a surfactant, and water. The masking material is applied to a surface which is to be protected from paint overspray or other mechanical process, allowed to dry, and paint is applied. After drying of the paint, the masking material is removed by peeling or water washing.
