2 Claims.
This invention relates to an improvement in paint compositions, particularly that based upon shellac and casein as a binder.
In its broadest sense the invention relates to a paint, consisting of a combination of shellac, casein and water, peculiarly compounded that it may be employed by the user either as a sizing coat, a stain killer, or a finish coat.
One of the peculiar objects of the invention is to employ the qualities of shellac combined with casein, and by adding thereto pigments which have increased dispersing qualities by reason of their association with alcohol, water and siliceous extenders, thereby creating, when properly compounded, a quick drying, water resistant sizing, and eliective stain killer, as well as a finish paint which can be applied equally as well with a brush or spray gun to surfaces of either hot or of normal temperature.
To exemplify the invention, the paint may be prepared by mixing materials in or about in the proportions specified, being in percentages, as follows:
Volatile matter:
It will be obvious that the above proportions may be varied one Way or another according to the qualities of the resulting produce desired. For example, greater quantities of water may be added if it is desired to apply the mixture solely as a size and Where a finish coat is not the end desired, and greater or less amounts of the pigments and the coloring materials may be added to attain the color, consistency and covering quality of the compound when used as a stain killer, or finish coat paint.
In compounding the above formula, it is necessary that the dry ingredients in the proportions above specified be thoroughly sifted and mixed.
The shellac resin in about the proportion given is then dissolved in the proportion of alcohol indicated, to which should then be added the Water previously heated to a temperature of about 140 Fahrenheit. This latter volatile solution should then be poured into the dry mixture and stirred untila resulting smooth compound or paint is attained. If a thinner coat is desired, additional amounts of water at about F. may be added.
It has been found that unless the several ingredients are combined in approximately the order given that a satisfactory compound does not result, and it is peculiarly a fact that the resulting mixture is not achieved unless the Water proportion is heated to about the temperature stated. The reason for this is that the shellac content and the casein content are of a gumlike consistency and without the application of heat to the water it will not be dispersed therein in such form as to make effective contact and combination with the zinc sulphide, calcium carbonate and siliceous extenders and pigments.
The combination of the ingredients in the manner stated results in a paint that can be applied With either a brush or spray gun and is one which can be spread without difficulty, will not show brush marks, laps, or other defects. It may be applied to hot surfaces, such as radiators, hot water tanks and the like with equal facility as to plaster walls, cement, wood composition board and the like. It has also been found to be and is an effective stain killer, and will prevent bleeding stains and discoloration, and furthermore when used as an under-coater it will form an almost perfect bond to the material to which it is applied and will not peel off due to changes in temperature and relative humidity to which it is subjected.
The formula given above may be varied to the extent of the percentage of the calcium carbonate and siliceous extenders and pigments used, and the term pigment is used both in the sense of filler and coloring matter as well.
Having thus described my invention, What I claim and desire to secure by Letters Patent, is:
1. The herein described paint composition sprayable, brushable and free flowing at normal temperature comprising 53% volatile matter consisting of 55 parts Water and 45 parts alcohol, and 47% nonvolatile matter consisting of 35 parts shellac resin, 8 parts casein, 12 parts zinc sulphide, 5 parts calcium carbonate and 40 parts siliceous extender.
2. The method of preparing a paint composition, sprayable, brushable, and free flowing at normal temperatures, comprising 53% volatile matter consisting of 55 parts water and 45 parts alcohol, and 47% nonvolatile matter consisting of 35 parts shellac resin, 8 parts casein, 12 parts zinc sulphide, 5 parts calcium carbonate and 40 parts siliceous extender, consisting of dissolving the shellac resin in the alcohol, heating the water to about 140 F. and adding the resulting solution to said other ingredients and stirring 'the same until a smooth sprayable and brushable product is attained.
