Free industrial recipes of adhesives and sealants

Liquid glue, glue for plaster molds, cardboard, paper and for gallantry, label glue and much more...

By adhesives we mean gummy or gelatinous substances that serve to bond two surfaces together. Usually they are substances that swell in water and harden again after the water has evaporated; the typical example of this is the common wood glue.

Another class of adhesives softens or melts in the heat and, after setting by cooling, bonds the surfaces to be glued together; this includes, for example, shellac.

Modern adhesives often belong to the group in which the water is replaced by an organic solvent. As an example, one can take the rubber solution and the celluloid glue.

The composition of the adhesives can generally be varied indefinitely. Each recipe must be adapted to the purpose for which it is used. Especially with regard to consistency, even the person of the processor plays a major role; the recipes must therefore always be tailored to the specific purpose. For example, an adhesive that works well for sticking shoe boxes can be completely unusable for sticking cardboard packaging for foodstuffs due to an unpleasant odor.

The surfaces to be bonded must always be clean. The adhesive is applied in a thin layer. If the substances to be bonded are porous, the pores must first be closed with a thin adhesive solution.

Dissolving casein

For a normal thick solution, take about 3 liters of water per kg of casein. The water is put cold in an enameled pan and the dry casein is added, stirring well; no lumps should form.
After this, 60 g of strong ammonia (spirit of salmiak) is added per kg of casein and the pan is now placed in a second larger pan filled with hot water (or on a water bath). The casein solution is now slowly heated to 70'8451; heated, which takes about half an hour. Too high a temperature should be avoided as the solution will become too dark in this case. After the casein has completely dissolved, you can dilute with warm water to the desired consistency. The glue obtained can be used just like normal wood glue, both hot and cold.

Casein can also be dissolved with borax. To do this, in the same order as with ammonia, mix 1 kg of casein with 4 to 6 l of cold water, add 150 g of borax and stir cold until the casein begins to soften: this takes about 15 minutes. After this, the mixture is again placed on or in a water bath, stirring well, at 70 &8451; heated until the solution is completely clear.

If one wants to make the casein solution very thin, part of the ammonia or borax is replaced by trisodium phosphate. Since the casein solution is perishable, it is recommended to preserve the solution with 2% sodium benzoic acid or salicylic acid or 0.5% carbolic acid.

Note: Casein must not come into contact with copper.

Casein is an animal protein found in milk and sports nutrition.


Using wood glue or bone glue.

To make a good glue solution, it is necessary to let the glue swell well in water before heating. With thick table glue, this can take up to two days. Nowadays, ground glue is also commercially available, which absorbs enough water in a few hours to be dissolved by heating.

After the glue has absorbed enough water, it is liquefied by placing it in a container of hot water; the temperature should not exceed 70'. Higher temperatures and prolonged heating should be avoided, as the water then acts on the adhesive and products are formed by so-called hydrolysis with a very low adhesive force.

Liquefaction of the glue is best done in a glue pot specially made for this purpose, the inner pot of which is tinned, while the outer pot, in which the hot water comes, can consist of any material.

When gluing with this normal wood glue, it must be ensured that the surfaces to be glued are made so hot that the glue does not solidify on them before the surfaces are firmly pressed together. The best adhesives must be used to deliver good work.

For gluing thin veneer, a glue with a high viscosity is used, which means a glue that already gives a viscous solution in a low concentration. A solution that is too thin has a tendency to come through the thin layer of wood to the outside and spoil the beautiful surface of the veneer.


Liquid glue

Bone glue 46,7 dl
Water 46,7 dl
Sodium nitrate 6,6 dl

The sodium nitrate (Chili saltpeter) is dissolved in cold water. The glue (finely ground) is soaked in this solution for two hours and then melted on a water bath at 60-70℃. After this, the mixture is kept at the specified temperature until the glue remains liquid after cooling to room temperature; this process takes several hours. Finally, one preserves with a few tenths of a percentage of carbolic acid or salicylic acid.

Albumin glue

Blood albumin (90% soluble) 100 dl
Water 170 dl
Ammonia (s.g. 0,90) 4 dl
Slaked lime 3 dl
Water 10 dl

The dry blood albumin is first stirred with most of the water, after which the mixture is allowed to stand for several hours. The soaked albumin is now stirred until dissolved, after which the ammonia is added with slow and careful stirring. Stirring too quickly causes the mass to foam. The lime is now stirred with a little water to form a thin milk of lime and carefully added to the albumin solution; after this the mixture is stirred for a few more minutes. One should not add too much lime as the glue then solidifies into a jelly-like mass. With the correct proportions, the glue remains usable for several hours. The correct ratio of albumin to water must be determined by a small test, as the viscosity of the glue must be adapted to the purpose and since the properties of albumin are not always the same.

A very good glue is also obtained by adding a quantity of paraformaldehyde. On 100 dl of blood albumin one takes as much water as necessary (140 to 200 dl), 5½ dl of ammonia (0.90) and 15 dl of paraformaldehyde. The albumin is dissolved just as before; only then is the paraformaldehyde added, neither too quickly nor too slowly. The mixture becomes thicker and thicker and it must be ensured that the entire amount of paraformaldehyde has been added before the solution solidifies or gelatinizes. At this stage, it is difficult or impossible to stir the adhesive. However, the thickened mass becomes liquid after about an hour and then has the right consistency. In this state the glue remains for about 8 hours. When the glue now solidifies again, it is insoluble and otherwise unusable.

This glue can also be completely processed cold. It is better to compress the workpieces hot. This glue is often used in the construction of aircraft, where the highest demands are made, as it is also no longer sensitive to moisture.

Silk stockings repair

Silk stockings can be repaired almost invisibly very quickly with the help of a caoutchouc adhesive. For this purpose, pure white raw rubber is allowed to swell in dichloroethylene and then diluted to a soft ointment-like paste.
With this paste you cover a piece of fabric of exactly the same color, place it on the hole and smooth the fabric with a hot iron. The solvent evaporates almost immediately.
The stockings can then be washed with warm water.

Mowilith adhesive.

An adhesive that can be used to stick almost anything, consists of a thick solution of polymerized vinyl compounds in solvents such as ethyl acetate and other esters. With this solution you can, for example, attach fabric or felt to almost all metals.

In addition to this synthetic resin, which is marketed under the name Mowilith, excellent adhesives can also be made with the acronals, also highly polymerized organic compounds.

In general, modern synthetic resins and synthetic lacquers have excellent adhesive properties and still offer great possibilities here. They are sometimes still too expensive for daily use.

In certain cases, eg in the plywood and plywood industry, the use of a synthetic resin as an adhesive offers enormous advantages. After all, only with this it is possible to obtain a glue seam that is absolutely waterproof.

Ethyl cellulose adhesives

First, a solution of ethyl cellulose is made:
Ethyl cellulose 10 dl
Ethyl alcohol 80 dl

Rosin ester 60 dl
Dammar (wax free) 20 dl
Dibutyl phthalate 20 dl
Now enough of the two solutions is mixed until an adhesive with the desired properties is obtained.

The proportions can be varied widely and it is finally possible to make mixtures completely without solvent, which have to be applied in a molten state. The adhesive strength is then exceptionally high, even in the cold, and remains for a long time. A melting sealant must contain at least 8% ethyl cellulose.

These ethyl cellulose adhesives are suitable for bonding cellophane to paper, to sheet metal, with ethyl cellulose, for sheet metal to paper, paper to paper and fabric to fabric.
