A PROCESS OF MANUFACTURING WEATHERPROOF OIL COLOURS OR PAINTS
Year: 1884

page_text: I OTTO WOLFF, Patent Agent of No 12 Schloss Str: in the City of Dresden
in the Kingdom of Saxony and German Empire do hereby declare the nature of
my Invention for A PROCESS OF MANUFACTURING WEATHERPROOF OIL COLOURS OR
PAINTS a communication to me by August Then Bergh of the City of Dresden
aforesaid to be as follows:-
+
This Invention relates to an improved process of manufacturing weather proof
oil colors or paint-Oil colors or paints, which are so absolutely necessary for the
preservation of wood, metals, stucco and other materials or objects, have up to the
present time not been manufactured with sufficient care.
The process of the conversion of the oil varnish into a resinous substance and the
facilitating of the said process so as to prevent the penetration of dampness, has
not received sufficient attention and on the other hand the hardening of the color
or paint, by adding exceedingly bard substances, has been overlooked, but is necessary
in order to enable the color or paint to withstand the injurious effects produced by
the continuous friction of the rain, dust and sand.
I have succeeded in finding a substance by means of which oil colors or paints
are freed from the faults abovementioned by adding an extremely hard material
which has been previously submitted to the action of fire and then converted into
powder to the oil varnish,
This substance contains 25% silicic acid (Si O₂) and also oxide of lead (Pb O)
oxide of Zink (Zn O) oxide of tin (Sn O₂) peroxide of iron (Fe O) oxide of copper
(Cu O) Aluminium (Al, O₂) peroxide of manganese (Mn O) calcareous earth (Ca O)
Magnesia (Mg O) and Sulphur (S) in such favourable proportions for the preparations
of weatherproof oil colors that in the opinion of competent experts the so prepared
oil colors or paints, with the addition of burnt colors in the various requisite shades,
are perfectly able to withstand dampness and all atmospheric influences or effects of
the weather as the resinous process is not only facilitated by the addition of the
aforesaid silicic compounds but the paint or color is also rendered hard or
indestructible.

the Kingdom of Saxony and German Empire do hereby declare the nature of my
Invention for "A PROCESS OF MANUFACTURING WEATHERPROOF OIL COLOURS OR
PAINTS a communication to me by August Then Bergh of the City of Dresden
aforesaid and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This Invention relates to an improved process of manufacturing weatherproof oil
colors or paint-Oil colors or paints, which are so absolutely necessary for the
preservation of wood, metals, stucco and other materials or objects have up to the
present time not been manufactured with sufficient care.
The process of the conversion of the oil varnish into a resinous substance and the
facilitating of the said process so as to prevent the penetration of dampness has not
received sufficient attention and on the other hand the hardening of the color or
paint, by adding exceedingly hard substances has been overlooked, but is necessary
in order to enable the color or paint to withstand the injurious effects produced by
the continuous friction of the rain, dust and sand.
I have succeeded in finding a substance by means of which oil colors or paints
are freed from the faults abovementioned by adding an extremely hard material
id est a silicic compound of silver slag or lead slag-which has been previously
submitted to the action of fire and then converted into powder to the oil varnish.
This said substance contains about 25% silicic acid (Si O₂) and also a small
percentage of oxide of lead (Pb O) oxide of zinc (Zn O) oxide of tin (Sn O₂) protoxide
of iron (Fe O) oxide of copper (Cu O) Alumina (Al, O,) protoxide of manganese
(Mn O) silicious oxide of calcium (Ca Si O,) Magnesia (Mg O) and Sulphur (S)
in such favorable proportions for. the preparation of weatherproof oil colors that
in the opinion of competent experts the so prepared oil colors or paints with the
addition of burnt colors in the various requisite shades, are perfectly able to
withstand dampness and all atmospheric influences or effects of the weather as
the resinous process is not only facilitated by the addition of the aforesaid silicic
compounds but the paint or color is also rendered hard or indestructible.
'
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is:-
The process or method of preparing indestructible or weatherproof oil colors or
paints by adding the above described substance with or without the admixture
of burnt colors to the oil varnish substantially as described in the foregoing
specification.
