Features of Desmokol glue and rules for its use
Polyurethane adhesive appeared on the Russian market quite recently, but thanks to its excellent technical characteristics, it quickly became one of the most popular adhesives suitable for joining various types of surfaces. Using Desmokol glue, you can easily fix a chair by attaching a broken leg, glue linoleum that has fallen off the floor, or repair shoes whose soles have come off.
Using this universal adhesive, you can join a variety of materials: fabric, plastic, leather, metal and even glass. In any use, a high level of fastening reliability and excellent results are guaranteed.
Composition and characteristics of glue
Desmokol glue contains polyurethane resins, an organic solvent and various modifying components. This product is widely used in shoe repair and production. Due to its ability to securely join different types of surfaces, the adhesive is used to bond an upper made of leather or fabric to a sole made of polyurethane, PVC, rubber or thermoplastic. When casting PVC soles, Desmokol glue is also added, which significantly increases the strength of the joint between the materials.
The adhesive composition has many advantages compared to other similar substances.
- The glue is completely transparent, so after repair the joint is invisible, which allows you to completely restore the original appearance of shoes or other products.
- Polyurethane glue is not afraid of water.Using this product you can glue surfaces whose humidity reaches 25%. "Desmokol" glue is often used for repairing rubber boats, hunting and fishing equipment.
- The universal adhesive composition does not collapse in the cold and does not crack under the influence of weights.
- It is convenient to work with glue, since it takes some time for it to dry completely, which means it is possible to adjust the gluing location if necessary.
- Durability and reliability of the connection. Two materials glued together with Desmokol form a single whole.
- The seam is not only durable, but also elastic, without excessive rigidity.
On sale, glue can be found in different packages and conditions. For home repairs, small 50 ml tubes or 1 liter jars are most convenient. On an industrial scale, 20 or 200 liter barrels are used.
There is glue in the form of granules, which you need to dilute yourself with a solvent. The purer the solvent, the higher the quality of the adhesive.
Storage and precautions
The Desmokol adhesive will retain its unique properties and characteristics only if stored correctly. The main condition for the safety of the product is the tightness of the packaging and maintaining the temperature in the range from +10 to +25°C. Under such conditions, the mixture will not lose its qualities for 1 year.
Important!
Desmokol contains a solvent - a highly flammable substance. You should not work with glue near an open fire; in addition, the room must have a good ventilation system.
Instructions for use "Desmokol"
There are three ways to apply polyurethane glue to the surface and glue the parts together.
- The usual way. The surfaces to be bonded are cleaned and degreased, after which a thin layer of glue is applied to them. After 10 minutes, the procedure is repeated two more times and the surfaces are pressed against each other.
- With heating. The cleaned surfaces are lubricated with an adhesive and after 10 minutes heated with a hairdryer to 80°C.
- Wet method. Surfaces are thoroughly cleaned and moistened with water. A thin layer of glue is applied, the parts are compressed and placed under a press. The resulting grip will be the tightest and most reliable.
The author of the site purity-en.htgetrid.com figured out what rules must be followed when working with Desmokol glue and how to pre-treat the surfaces to be glued.
You can achieve a reliable connection of surfaces, which allows you to provide your favorite shoes with a second life, only by thoroughly cleaning the parts from dust and dirt, old glue, and pieces of material. After cleaning, the surfaces are treated with sandpaper and degreased.
When the preparatory work is completed, glue is applied to the parts with a layer of 2-3 mm and the composition is allowed to dry for 7-10 minutes. If the material being processed is too porous and the glue is completely absorbed, you can apply an additional layer and wait a little again. As a result, the adhesive layer should dry and not stick to your fingers.
Desmokol glue for shoes will provide the best connection if it is heated to a temperature of 80°C. For these purposes, you can use an industrial or home hair dryer, as well as other heating devices. The heated surfaces are pressed against each other as tightly as possible. Usually, high-quality glue does not require the installation of additional weights or clamps, but some craftsmen use some kind of weights for safety.
Shoes can be worn a day after the repair.
Advice
To glue shoe parts that are constantly exposed to moisture or temperature changes, you can add the Desmodur additive to the glue in a ratio of 1:7. This will ensure thermal resistance and strength of the connection.
How to dilute granular Desmokol
To dilute glue that is in a granular state, it is necessary to prepare pure acetone in a ratio of 1: 10, that is, for 20 g of glue - 200 ml of solvent. Pour acetone over the granules and leave for 8 hours. The result will be a heterogeneous transparent mixture, which must be mixed until smooth. In the instructions, the manufacturer notes that the process of dissolving the granules will proceed faster in a warm room with an air temperature of +25 to +30°C.
