Abstract:
A vehicle masking material and method of use. The masking material in one embodiment includes polyvinyl alcohol, ethyl alcohol, a plasticizer, a surfactant composition including a functional derivative of a fluorinated alkyl chain, 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.

After drying of the paint, the masking material is removed by peeling or water washing.
Abstract:
A method of painting a clay body and maintaining a durable, decorative surface finish by providing a barrier film layer between the paint coat layer and the clay body such that the oily substance contained in the clay body is blocked from permeating through the barrier film to adversely affect the paint coat layer.
Abstract:
A splendid tentative surface protective coating which is useful in treating a surface of a substance by soldering or plating and which is peeled off easily from the surface after the treating is formed by preparing a solventless or solvent free type screen ink based on essentially an ultraviolet ray-curable rubbery elastomer, applying a coating of the ink on the surface of the substrate by screen printing or thin film coating, and curing the coating of the ink by irradiation with an ultraviolet ray. The tentative surface protective coating can reproduce exactly a pattern of a mask or screen, have a high chemical resistance and heat resistance, even if it has a thin thickness of 30 .mu.m, and have no afraid of deformation caused by heat curing, whereby a precise and shortened surface treatment of the surface of the substance can be afforded. Also, working environment is improved, and air conditioning equipment can be dispensed with owing to an absence or diminishment of an organic solvent. In addition, according to the present invention, an excellent ink composition is provided which is much suited to screen printing.
Abstract:
A method of coating a metal part with a peelable mask which is resistant to attack by the strong acid and strong base etchants used in chemical milling is disclosed in which the metal part is surfaced with a layer of polyvalent metal salt, such as calcium nitrate, and then immersed in a high solids content anionic emulsion of coalescent rubbery particles heavily pigmented to contain at least about 45% total solids content and at least 20% pigment, the pigment to binder ratio being from 0.75:1 to 1:0.51. The salt-surfaced metal part is held in the anionic emulsion until the desired coating thickness has been anodically deposited thereon, and then the coated part is removed and baked to complete the formation of the mask. The rubbery particles are preferably constituted by an anionic polychloroprene homopolymer emulsion which is used in admixture with a curing agent for the homopolymer, like zinc oxide, and a polyvinylidene chloride latex. Sodium bichromate is included with the polyvalent metal salt to enhance corrosion resistance, and a silicone release agent is included to control adhesion to the metal substrate.
Abstract:
A partial painting method suitable for partially painting a workpiece or article of a complex surface shape. A surface of the workpiece is coated with strippable paint. The coated strippable paint is dried into a strippable film on the workpiece surface. A laser beam is applied to the strippable film along a prescribed cutting line so as to cut the strippable film. A portion of the strippable film corresponding to a first area of the workpiece surface to be painted is peeled off, while the remaining portion of the strippable film is left adhering on a second area of the workpiece surface to remain unpainted, and thereby masking of the workpiece is completed. The first area is then painted with a paint to form a final paint coating. The strippable paint contains powder, such as of graphite, having a substantially high light energy absorptivity, so that the strippable film can reliably be cut by the laser beam without damaging the surface of the workpiece which may be molded of synthetic resin that is relatively soft and is easily softened when heat is applied.
Abstract:
Windowed face plates are provided by applying to selected portions of the surface on one side of a transparent face plate a poorly adherent coating to provide easily strippable film portions lightly adhered to the plate, and then overcoating the same side of the plate with a heavily pigmented organic solventbased paint to form an opaque brittle film of paint which adheres strongly to the exposed surface of the plate and the strippable film portions to provide an opaque plate. An adhesive tape is then applied over a film portion which it is desired to remove and peeling off the adhesive tape causes the strippable film portion to be pulled off with the overlying paint attached thereto to thereby provide one or more windows in an opaque plate.
Abstract:
A PRIME COAT OF THERMOPLASTIC RELEASE MATERIAL IN APPLIED TO THE METALLIC OR THERMOSETTING RESIN SURFACE OF AN AIRPLANE OR RADOME PRIOR TO COATING THE SURFACE WITH AN OUTER COAT OF THERMOSETTING, RESIN-BASED PAINT. THE THUS INTERPOSED THERMOPLASTIC LAYER IS USEFUL IN THAT IT AND THE OUTER, THERMOSETTING RESIN-BASED PAINT MAY BE EASILY REMOVED, AT A LATER TIME, BY THE STEPS OF (A) APPLYING HEAT UNTIL THE THERMOPLASTIC RELEASE MATERIAL SOFTENS AND (B) SCRAPING OR SANDING.
