Description
COMPGSITION FOR MAINTAHIING CLEAR VISION 1N WENDSHELDS No Drawing. Application June 22, 1953,
Senal No. 363,415 5 Claims. (Cl. 106-13) This invention relates to the maintenance of clear vision in Windshields and the like and to compositions therefor.
admixture wit a volatile hydrocarbon solvent and a finely divided inorganic, non-siliceous adhesion-promoting agent which with rubbing changes the polysilicane from a form which is soluble in hydrocarbon solvent to one which is insoluble therein and rubbing the mixture on the surface with a fabric to cause the polysilicane to adhere to it in gasoline, alcohol agent is described as selected from the group consisting of carbon black, rogue, barium sulphate, lithopone and the precipitated fluorides of calcium, barium, strontium and lithium.
It has now been found that much better results are obtained when the silicane is applied to the window surface with an adhesion-promoting or friction agent consisting of carbon black and a cleaning agent, the latter having a particle size greater than the carbon. This combination substantially reduces the time and etfort necessary to efhesion promoting friction agent does not produce the repellent film as easily as does the simultaneous use of the two together. This despite the fact that the cleaning agent may be or" a type which does not produce the repellent film if used alone with the silicane, e. g. the cleaning agent may be a siliceous material, which is absolutely inert to the silicane. Cerium oxide used alone is extremely efiective in removing the film but mixed with carbon black assists in producing the film. Frequently large window surfaces require treatment and it will be recognized that a reduction of as much as 80% in the time and effort required in applying the silicant film is of importance, particularly when many vehicles have to be serviced. The reduction of effort with the silicane. When carbon alone was used as the adhesion-promoting or friction agent 40 to 50 strokes States Patent along one line were required to produce optimum results whereas a mixture of polish glass without scratching it; e. g., very fine silica, diatomaceous earth, rouge, cerium oxide. it is desirable to use as cleaning agent a powder which itself has some value in directly promoting the production of the repellent film, and all of the coarser powders listed in the prior patent have value in this respect. Of these, rouge, cerium oxide and the fluorides, in order have the greatest etlect, and rouge therefore is selected as preferred as the most active cleaning agent for this purpose. The particle size of the cleaning agent is greater than that of the carbon black which is about 25 A.
The relative proportions of the active friction agent and the cleaning agent may be varied over a long range with median proportions of these material are however preferred, and the range from 15% rouge, carbon black by weight; to 50% rouge, 50% carbon black is most useful.
The following specific compositions are illustrative:
l) 4 grams acetylene carbon black, 4 grams rouge and 11 grains of the silicane.
(2) 17 grams of carbon 45 grams of silicane.
(3) 9 grams of acetylene carbon black, 1 gram of rouge and 22.5 grams of silicane.
Of the many polysilicanes particularly suitable for use vehicles. it is easily applied, iency and withstands abrasion substantial periods. moving vehicles diethyltetraamyldisilicane provides higher repellence but requires more rubbing. For use at still higher speeds octaamyltrisilicane produces a still higher degree of repellence.
As disclosed above these, and like compositions are black, 3 grams of rouge and tetraethyldiamyldisilicane is on relatively slow moving has adequate water repela particle size larger than that of the carbon black.
2. The composition defined in claim 1 in admixture with a hydrocarbon solvent.
3. The composition defined in claim 1 wherein the silicane is diethyltetraamyldisilicane.
4. The composition defined in claim 1 wherein the silicane is tetraethyldiamyldisilic-ane.
5. The composition defined in claim 1 wherein the silicane is octaamyltrisilicane.
