Description

ALBERT C. HOLZAPFEL AND PAUL WALTHER, NEW YORK, N. Y.
No Drawing.
To all whom it may concern:
Be it known that we, ALBERT C. HoLzArrE-L and PAUL WVALTHER, subjects of the King of Great Britain, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Compositions for Coating New Iron and Steel, of which the following is a specification.
Our invention relates to a composition of matter adapted for coating new iron and steel, and which may be subsequently covered with a paint of a lighter color, while not necessarily restricted to this use.
An important object of our invention is to provide a composition of matter of the aboi e mentioned character, which will firmly adhere to the new iron or steel, when applied thereto, and which is insoluble in the paint of lighter color, applied thereto.
Other objects and advantages of the invention will be apparent during the course of the following description.
It is well known thatbituminous solutions are adapted to-more firmly adhere to new iron and. steel, when applied thereto, than ordinary oil paints. This bituminous solution ordinarily contains asphaltum and coal tar pitch, dissolved in hydrocarbons. Owing to the black color of this bituminous solution, it is customary, after the same has suitably dried upon the iron or steel, to coat the same with a paint ofa lighter color, thus rendering the material more attractive in appearance. A marked disadvantage encountered 'in connection with the use of bituminous solutions, as above indicated, is that after drying, they are dissolved by the lighter colored oil paints applied thereto,
whereby the lighter colored paints are discolored. Owing to this disadvantage, the bituminous solutions are undesirable for many purposes for which they would otherwise be used. h
In accordance with our invention, we provide a composition of matter, possessing all of the advantages of the ordinary bitu minous solution, but being free from their objections. Our improved composition of matter comprises the following mgredients,
COMEOSITION FOR COATING- NEW IRON AND STEEL.
Specification of Letters Patent. Patented J an. 20, 1920.
Application filed November 13, 1918. Serial No. 262,369.
preferably combined in the proportion indicated:
12 parts by weight of stearin pitch,
20 parts by weight of asphaltunn'and 68 parts :by weight of tar oil.
The proportion of the asphaltum to the stearin pitch may be reduced or increased according to the qualities of either or both materials, the principal feature of the invention being the use of stearin pitch to render the composition insoluble by the light colored oil paints, when applied thereto.
- The composition produced as above indicated is in the form of a bituminous varnish or solution possessing all of the adhesive and protective properties of the usual bituminous or bitumastic solutions, but is not dissolved by ordinary oil paints, which may be subsequently applied to thesame so that the oil paints of light color can be readily applied without discoloration.
It is to be understood that the form of our invention herewith described, is to be taken as a preferred example of the same and that various changes may be resorted to in the.
proportion of the several ingredients and that known chemical equivalents may be employed without departing from the spirit of parts by weight oftar oil.
In testimony whereof we aflix our signatures in presence of two witnesses.
