ALBERT CJXHOLZAPFEL, orgmw YORK, N. Y:
SURFACE-COATING COMPOSITION.
1,379,018. No Drawi'ngt.
To all whom it may concern:
Be it known that I, ALBERT C. HOLZAPFEL, a subject of the King of Great Britain, residing at New .York, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Surface-Coating Compositions, of which the following is a s ecification.
This invention re ates to a surface coating composition suchas a aint, varnish, or the like, rimaril inten ed for coating metal, and particu arly iron and steel, but adapted for coating wood and other materlals.
P1tches derived from the treatment of o ls and fats, such as stearin pitch, alm oil pltch, and the like, have been use in the manufacture of surface coating compositions, as for example, the surface coating composition described in, Letters Patent No.
, 1,313,252, granted ,to Paul Walther and me oils and fats is Ma 4, 1920. In such compositions, gums suc as copal, dammar and the like have been used, and it has heretofore been consid ered essential to employ such gums in producing a a1nt,,varmsh, or the like, in which pitc derived from the treatment of present as a material or substantial ingredient.
Now, I have discovered that a satisfactory varnishpr vehicle for the pigment if the composition is used in the manufacture of pamt, can be made from pitch derived from the treatment of oils and fats by merely dlssolvingfrom-approximately 30 to 40 arts of it by weight in from to 70 arts y weight of tar oil such as a distil-.
at e of tar oil, of from 70? to 120 flashpoint, or other h drocarbon solvent of the itch, wlthout t e employment of copal, airlilmar, or other gum heretofore used therewi i If the composition is to be used in the manufacture of aint, from approximately 1 to 59 and re erably from 20 to 50 parts by wel ht'o a sultab e pigment is incorporated t erein.
Linseed oil or any of the oils commonly such oil is not necessary. If suchoil s used, I prefer to add it in approximately the proportions of from approx1mately'5 to 20 parts by weight to from 80 to 95 arts by weight of the solution'gf thestearin or Specification of Letters Patent.
. ing of approximatel Patented May 24, 1921.
Application filed Kay 25, 1920.- Scrial No. 884,174.
\ of the year and the temperature at which the varnish or paint is to. be applied, as will be readil understood by those skilled in the art. t is to be understood that these proportions may vary widely within the limits of the solub1lity of the pitch in the solvent used, but the proportions set forth above have been found to be most satisfactory. Similarly, the proportions of the linseed or other similar 011' to the pitch solution may vary within wide limits, but the oilishould not be added in excess of 20 per cent. by
weight of the whole.
It is to be understood that while tar 011 such as a distillate of tar oil of from 70 to 120 fiashpoint-is preferred as the solvent for the stearin or like pitch, other hydrocarbon solvents may be used with a considerable measure of success and are, to such extent, equivalents of the tar oil. Similarly, while I prefer to employ linseed oil, if a paint oil is employed, other paint oils are to be regarded as equivalents of the linseed oil for use in my composition.
The varnish or the paint produced in accordance with m invention is applied in the usual way, eit er by brush or spray, and dries rapidly, usually within an hour, with a good, smooth gloss.
I claim:
1. A surface coating composition consisting of approximatel from 30 to 40 parts by weight of pitch erived from the treatment of oils and fats and from 60 to 70 parts by weight of a hydrocarbon solvent. 2. Asurface' coating composition consisting of approximately from 30 'to 40 parts by weight of pitch derived from the treatment of oils and fats and from 60 to 70 partsby weight of tar oil.
ing of approximately from 30 to 40 parts by weight of stearin pitch and" from 60 to 70 parts by weight of tar oil.
4. A surface coating composition consistfrom 30 to 40" parts by weight of pitch erived from the treatment of fats and oils, from 60 to 70 parts by weight of tar oil, and apiproximately from 1 to 50 parts by weight 0 pigment.
5. A surface coating composition consisting of approximately from 30 to 40 parts by weight of stearin pitch from 60 to 70 parts by weight of tar oi, and ap' roximately from 1 to 50 parts by weig t of 5 pigment.
6. A surface coating composition consisting of approximately from 30 to 40 parts by weight oiiste'arin pitch, from 60 to 70 parts by weight of tar oil, and approxi- 0 mately from to 50 parts by welglxt of pigment. l
a 7. A surface coating composition consisting of approximately from to parts by weight ofpitch derived from the treat- 15 ment of oils and fats, from 60 to 70 parts b weight of tar oil, a pigment, and a paint oi 8. A surface coating composition consisting of approximatel from 30' to 40 parts by weight of pitch erived from the treatment of oils and fats, from 60 to 70 parts 20 by weight of tar oil, approximately from 20 to parts by wei ht of. igment, and nfit to exceed 20 parts y weig t of a paint 0 a -9. A surface coating composition consist- 5 ing of approximately from 30 to 40 parts by weight of stearin pitch, from to parts by weight of tar oil approximately from 20 to 50 parts by wei ht o a pigment,
and not to exceed 20 parts y weight of linseed oil. In testimon whereof I aflix my signature. in presence 0 two witnesses.
