LEAD COATING ABTIOLEG.
Io Drawing. Application filed August 17, 1927, Serial li'o. 213,708, and in Germany August 30, 1880.
The present invention relates to the lead coating of articles and to the composition of such lead coatin According to tilie present invention articles are provided with a smooth securely adhering 'coatin of lead which is resistant to the action 0 the weather,by a painting or coating means obtained from a binder and very finely divided lead owder to which latter are added suitable su stances for preventing previous oxidation.
A number of substances particularly suitable for this purpose are antimony, tin, bismuth, cadmium, aluminum, zinc, magnesium,
manganese and the like metals.
In order to obtain a 'uniform product an alloy of lead with the metals or mixtures of metals, such as for example, a tin-antimon lead or antimony-lead alloy is preferab y 2 used, which at the same time gives a coating which is mechanically more resistant and harder than in the case of pure lead.
The coating is composed essentially of the lead and binder. A very small percent of the 2 antimony or other metal or metals in respect to the amount of lead used is suflicient to accomplish the desired result. The other metal or metals do not add materially to the body of the coating, but improve the quality of the lead coating, and articularly prevent the oxidation of the lead A paintin or coating means consisting of the very fine y divided metal powder of a tinantimony-lead alloy and a binder such as lin- 36 seed oil 'ves on painting a perfectly smooth non-flaking coating which adheres firmly to the base. When painted on iron 11 very powerful rust preventative is obtained, the union of the paint with the base being, in this case,
40 so intimate that lead penetrates into the uppermost layers of the iron and can be detected therein.
Other substances can be used instead of the above mentioned de-oxidizing substances, or substances preventing the oxidation of the finely divided lead, andmaybe added partially to the lead or to the binder.
I declare that what I claim is 1. A paint for applying a lead coating to an article including a finely divided lead powder, one or more powdered metals adapted to prevent oxidation of said finely divided lead powder, and a binder.
2. A paint for up lying a lead coating to an article including a inely divided lead powder one or more powdered metals such as antimony, tin, bismuth, cadmium, aluminium, zinc, magnesium, manganese adapted to prevent oxidation of said finely divided lead powder, and a binder.
3. A paint for applying a lead coating to articles, consisting essentially of finely subdivided metallic lead and a binder, and having incorporated therein finely subdivided metallic. antimony for preventing oxidation of the lead.
4. A paint for applying a lead coating to articles, consisting essentially of, finely subdivided metallic lead and a binder, and having incorporated therein a comparativel small amount of finely subdivided metalllc antimony for preventing oxidation of the lead.
5. The process of protecting the surface of an article, which consists in applying to said surface a coating consisting essentially of finely subdivided metallic lead and a binder, and preventing the oxidation of the lead by the action of a second metal also in a finely subdivided state.
6. A paint for applying a lead coating to articles, consisting essentially of finely subdivided metallic lead and a binder, and having incorporated therein a comparatively small amount of another metal in a finely subilivjlded state for preventing oxidation of the 85 7. A paint for applying a lead coating to an article, including a binder and an alloy consisting essentially of lead and a small amount of another metal for preventing oxidation of 90 the lead.
In witnes whereof I aflix my signature.
