Abstract: Easily removable conformable coatings having a controlled thickness with a predetermined minimum value are obtained by the application of a composition comprising a mixture of a viscous carrier material and small particles of a second material by any known method. When both the carrier material and the particulate material mixed therewith are selected to have high dielectric constants, the mixture may be used to obtain coatings suitable for protection of circuit boards supporting high impedance electrical circuits. A mixture of a commercially available grease, e.g., Amoco RYKON (TM), with glass microspheres comprising up to 50% of the volume and preferably in the size range 3-5 mils, provides excellent dielectric conformal coatings for high impedance circuit boards. By contrast, by selecting both the viscous carrier material and the particulate matter mixed therein to have high conductivity, electrically conductive coatings for particularized users may likewise be obtained according to this invention.

Abstract: Temporary corrosion protection for fresh metal surfaces may be obtained by depositing a thin film of a protective organic compound, particularly a fatty acid ester, from a solvent, preferably a fluorocarbon on the surface to be protected. The film-forming esters are chosen to be self-removing by evaporation so that no cleaning is needed before carrying out processes which require a clean metal surface.

Abstract: A method of placing color indicia or tints on a porous surface includes the steps of forming a base layer on a surface, such as a floor, by applying a liquid layer of an unpigmented metal interlock acrylic finish to the surface, and allowing the base layer to dry. A pigmented layer of liquid metal interlock acrylic finish containing an acrylic polymer emulsion and pigment substance is then applied over the base layer in the form of an indicia, such as a decoration, advertisement, or pattern. After the pigmented layer has dried, a protective layer of liquid metal interlock acrylic finish is then applied over the pigmented layer and allowed to dry to protect the design, and the protective layer can be buffed to a shine. The method can be used to quickly and easily apply directional aids, advertisements, tints, or other colored indicia to a floor. Both the pigmented and unpigmented layers are readily removable with common detergents such as ammonia.

Abstract: A new and unique method of producing a mosaic-like work of art on a sheet of fabric material. Once the fabric and its basic color is selected, a coating of melted wax is applied to one surface thereof. After the wax is dry, the fabric is crackled so as to form random and skewed cracks. Dye is then applied which penetrates the cracks and is absorbed by the fabric, whereby random skewed lines are left in the fabric after the wax is removed. The random skewed lines define a multiplicity of contiguous areas to be selectively painted so as to render a mosaic-like work of art.
