Description

R XP. 2,339,317
Patented Jan. 18, 1944 PROCESS AND COATING MATERIAL FOR SURFACES Joseph W. Ayers, Milwaukee, Win, assiznor to Agicide Laboratories, Inc., Milwaukee, Win, a corporation of Delaware No Drawing. Application June 29, 1942, Serial No. 9,011
6 Claims. (Cl. 117-25) This invention relates in general to paint coatlngs and more particularly to a process and ma ierial for producing mat surfa-ze coating applicabie to a wide variety of surfaces.
A particular use for the material to be described is: the camouflaging of military equipment, helmets. and the roofs of airplane hangars or the like. The coating to be described may be modified to fulfill requirements for light-weight, resistance to abrasion, light absorption, and simplicity of application. The material has the additional quality of not only absorbing infra red rays but uniformly diffusing light projected thereupon, whereby a surface thus coated is relatively difllcuit to photograph.
Materials heretofore used for this purpose usually comprised a mixture with a paint base of pulverized cork, wood f ber or sand particles. The physical characteristics and behavior of these materials were objectionable in use principally because of the lack of bond between the particles and the paint base, the lack of wear-resistant qualities, and the diillculty in obtaining uniform textures. All of these objections are overcome in the present invention in which a principal object is the process of forming a coating having a mat surface of uniform texture resulting from the close bonding of pre-graded nut shell flour with a surface and a subsequent application of pigmentcarrying paint or lacquer thereon for producing desired color effects.
It is a further object of the invention to provide a mixture oi. a paint base and pro-graded nut shell flour in the form of a viscous liquid for application to surfaces.
These and other objects and advantages '"ill appear in the following description and claims.
In a preferred form, the surface to be coated is given a priming coat oi air-drying paint or lacquer and while this cost is in a "tacky" eondition, a pro-graded granulated nut shell flour is dusted uniformly thereon. The nut shell partlciea will embed themselves in the priming cont and thus he held in close proximity with each other on the surface. The rcsuiliiuu routing is preferably oven-halted in liilil to lliiulv luuul the particles and complete the drying of the prime cont.
After the above drying operation is completed. one or more coats of paint or pigment-carrying lacquer is sprayed on the resultant surfac to suit] the nut shell particles and to obtain a desired final shade of color.
A particular application for the above-described coating was prepared for the United States Government military h l in which walnut shell flour graded through a 12 to 20 mesh screen was applied to the priming coat, and after baking, two coats of synthetic standard olive drab enamel were sprayed upon the surface. The resultant coating proved to be extremely slstant, light-diffusing, and did not add excessively to the weight of the helmets.
Another modification ofthe coating material includes the application of clear or translucent adhesive to the surface and alter the application of nut shell flour, to cover the resultant surface with a clear or translucent lacquer coating which produces a natural-color surface dependent upon the color of the uncoated surface and the nut shell particles.
Further modifications include the preparation of pre-graded walnut shell flour mixed with prepared paints and lacquers and the resultant mixture sprayed directly upon the surface to be coated with a spray gun having a special nozzle.
Although thlsinventlon has particular merit as a camouilaging paint, other useful and ornamental etlects may be obtained. A particular application for the present invention is found in taking ad'.*antage ct the light-dlffusing characteristics in covering irregular or defective surfaces whereby such irregularities and defects are not apparent to the eye.
Having described my invention, I claim:
1. A process of applying granular coatings to surfaces including the application of a film of an air-drying adhesive said adhesive comprising a mixtur of cemcntitious material and volatile products to the said surface and while the said adhesive is still in a viscous state, the dusting of pie-graded nut shell particles thereupon and subsequently applying a coat of said adhesive over the dusted surface.
2. A process of applying granular coatings to surfaces including the application of a film of air-drying adhesive said adhesive comprising a mixture of ci-mentitiou'l material and volatile odde i0 tin \lili'l surface and while the said adlwsiuis iillil in a viscous state, the diluting of preiiuuin. \vnluut shell particles thereon and heatmg the dusted surface to dryness and then applyllg a coat of alr-dry'ng, color-carrying cementi. tious compound to the dusted surface.
3. A coating material for surfaces comprising a lnyeroi air-drying adhesive said adhesive comprising a mixture of cementitlous material and volatile products, a layer of nut shell hour particles of substantially predetermined size; em-
bedded in said adhesive and a covering film of a dryable cementitious compound.
4. A coating material for surface; comprising a layer 01' air-dryin: adhesive said adhesive comprising a-mixture oi cementitious material and volatile products, time: of nut shell flour particles oi substantially predetermined sizes embedded in said adhesive and a covering iilm oi a dryable cementitiour compound around with color pigment.
5. A coating material tor surfaces comprising a cementitious material mixed with volatile prodducts and nut shell particles of substantially predetermined size.
6. A coating material for surfaces comprising a mixture of air-drying lacquer, ground with color pigment, in combination with nut shell particles of substantially predetermined size.
