Abstract:
A method for protecting painted and other surfaces from being permanently marked by graffiti and particularly markings of flexible tip permanent marking pens comprising coating the surface with a removable composition consisting essentially of from 10 to 35% by weight of a polymer having a monomer content of from 25-70% by weight of a hard monomer, 15-50% by weight of a soft monomer, and 15-30% by weight of an acid monomer, the polymer having been solubilized with sodium hydroxide, potassium hydroxide, or mixtures thereof, from 0-15% of a potassium or sodium salt of a maleic anhydride adduct with a mixed alpha olefin having chain lengths of more than 30 carbon atoms, from 0 to 2% of a coalescing solvent selected from the group consisting of diethylene glycol monoethyl ether, diethylene glycol monobutyl ethyl and mixtures thereof; from 0 to 3% of defoamers, leveling agents, and mixtures thereof; and 90 to 45% by weight water, the composition having an MFT of less than 30.degree. C. and a pH of from 7.0 to 10.0 and allowing the coating to dry on the surface to be protected.
Abstract:
A temporary, protective plastic coating for an article, such as ornamental tubing, which may be sprayed on the tubing becoming adhered thereto and, upon nominal drying, a strip of material such as adhesive-backed tape is placed in contact with the coating over a full length in one dimension. The strip and the coating are bonded together with a strength at least as great as the film strength of the coating such that upon tearing off the strip, the plastic film directly in contact with the strip is also removed, enabling rapid removal of the remaining film on the article.
Abstract:
A STRIPPABLE PROTECTIVE COATING IS FORMED ON A SUBSTRATE, ESPECIALLY A VEHICLE BODY, BY SPRAYING FROM A MOLTEN COMPOSITION ONTO IT. THE MOLTEN COMPOSITION PREFERABLY CONTAINS A MIXTURE OF A FILM-FORMING COPOLYMER OF ETHYLENE AND VINYL ACETATE AND AN AUXILIARY POLYMER, PREFERABLY ANOTHER ETHYLENE/VINYL ACETATE COPOLYMER, OF MOLECULAR WEIGHT BELOW 10,000.
Abstract:
An automated process for producing exposed electrical contact areas on the conductor part of an epoxy coated bus bar. When the epoxy coating is in the glassy state, one can safely and economically, preferably via automated apparatus, put the epoxy into the rubbery state by positioning the bar and applying localized heat at a select area of the coating; monitoring the heating to above the glass transition temperature of the epoxy, bringing cutting tools into contact with the epoxy for cutting and removing the rubbery coating away from the bus bar, and cooling the bus bar to bring adjacent coating back to the glassy state, thereby leaving an exposed electrical contact area of conductor on the bus bar with little or no surface damage.
Abstract:
This method for painting a surface (S62) of a component (6) with a pattern includes at least the following steps consisting in applying a first coating product on at least a portion of the surface, automatically applying at least one portion of a mask (12) on a portion (Z62) of the surface, applying a second coating product and on the surface and removing the mask (12). Preferably, the mask (12) is at least partially automatically applied in the form of at least one layer (122, 124, 126) of non-atomized fluid, the layer being obtained by moving (A1) an applicator (16) delivering the non-atomized fluid along the portion (Z62) of the surface (S62) where the mask (12) is to be applied.
Abstract:
An applicator die for creating undivided ribbons of polymeric film and a method of using the die to apply an emulsified polymeric material in ribbons to a fully or partially finished surface of an automobile body. In one application, the ribbon is applied as a peelable film to an automobile body and in another application, a ribbon is applied to a rocker panel as an anti-chip coating. For both applications, the applicator die has an internal gallery and an outlet slot with flared edge surfaces to emit a laminarized ribbon of polymer-based material at a distance from the target surface where the opposite edges of the ribbon have become essentially parallel.
Abstract:
A coating process and device for producing a selective metalization, comprising the deposition of a metalization layer, on a motor vehicle lighting and/or signaling device part comprises an application, prior to the metalization, of a covering film to the portions intended not to be metalized, so as to protect the portions intended not to be metalized during the vacuum metalization operation and so as to bare the non-metalized portions after removal of the covering film.
Abstract:
An applicator die for creating and applying laminarized ribbons of polymeric film to a target surface, such as but not limited to a surface of an automobile body component. In one embodiment, the protective film is an aqueous emulsion of polyvinyl acetate and is used to create a continuous peelable film to protect a surface. In another embodiment, the polymeric is polyvinyl chloride and it is applied to create an anti-chip coating. The applicator die has an internal supply gallery and an outlet slot of complex shape to emit a laminarized ribbon of polymer-based material that allows the material to be applied directly to the target surface without masking. A robot is used to control movement of the die. The die includes temperature control.
