TECHNOLOGY OF MANUFACTURING ADHESIVE FOR ADHESIVE
PAPER AND RUBBER TO METAL
Glossary of terms
Stick an ordinary paper, a label, etc. on a smoothly polished metal surface, as it is known, is very difficult: the paper falls off very quickly. This inconvenience is easily eliminated by the following method: prepare a concentrated aqueous solution of soda, carefully wet the metal surface with a heated solution; then wipe it dry with a rag, cover with a thin layer of onion juice (cut the bulb in half and rub the place), additional paper is applied on top of it, greased with the following glue: take wheat flour, add to it as much sugar, pour this mash with cold water, to the density of sour cream, then brewed with sheer boiling water and stir until transparent. Paper pasted in this way, holds so tightly that it can only be scraped off with a knife.
To glue the rubber to the metal, the following glue is prepared: we dissolve shellac with a tenfold number of strong ammonia.
