Process for Producing a Fundamental Mass from which Varnish and
similar Coatings may be Made.
I, MAX BECKER, Chemist of 12 Heim Strasse, Berlin Germany, do hereby
declare the nature of my invention and in what manner the same is performed
to be particularly described and ascertained in and by the following statement:-
The object of the present invention is to produce a fundamental mass or liquid
from which to make such varnishes and other coatings as need not necessarily be
transparent, their main features being durability and great adhesive property. The
principal articles covered by this class are: Blacking, floor polish, varnish, furniture
polish and the like.
The varnish or polishing media made from the mass or liquid forming the object
of the present invention, besides being very durable and adhesive have the
advantage of being without smell, very economical in use and entirely free from
the outward stickiness which usually characterises this class of goods and owing
to which the high polish soon gets blurred by dust adhering thereto.
The process consists first in dissolving a borate in a steam or water bath, then
adding a coloring matter, or this may also be done later on according to the nature
of the varnish to be subsequently made; the solution is now heated to boiling
point and during uninterrupted stirring, a vegetable wax such as carnauba wax
added in small quantities and in such manner as to allow the first portion to entirely
dissolve before the second is added and so on. As soon as the necessary amount of
the vegetable wax is entirely dissolved, the whole solution remains on the fire or in
the bath until it becomes a thick mucilaginous mass. If the coloring matter has
been added previously, the product may now be poured into tins or other receptacles,
a constant hot temperature being kept up all the time. If however, the coloring
matter was not added, this should be done now and the whole solution allowed to
continue boiling until the said coloring matter has been evenly mixed therein.
A coating of this kind may be easily polished; it is first spread thinly and
evenly on the object in question by suitable means and after having been
allowed to dry, lightly rubbed with a soft brush, when a beautifully bright polish
will be obtained.
It is of course impossible to fix definite proportions for the ingredients composing
the mass, but the following may be considered as the average proportions :-7 parts
sodium biborate are dissolved in 100 parts boiling water and 15 parts carnauba
wax are added to the solution. This mixture may be used as it is for any purposes
for which the addition of a coloring matter is unnecessary. If however, it is
required to color the mixture, 2-3 % of aniline coloring matter or a correspondingly
higher percentage of organic coloring matter for instance 90 % should be added.
As an instance of the application of my fundamental mass I will now proceed
to give the proportions required to form a good polish or blacking for leather,
they are:-
90 parts sodium biborate,
1200 parts water,
20 parts nigrosine,
200

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is performed I declare that what I
claim is
1. The process for producing a fundamental mass for making polish varnish and
other coatings, consisting in first dissolving vegetable wax in a boiling borate
solution and then by continued boiling reducing the whole to a mucilaginous mass,
which may be worked up to the required polish or varnish by the addition of
colouring matters or other suitable substances substantially as described.
2. As an article of manufacture the fundamental mass produced by the herein
before described process.
