Glue "Desmokol" has another name - SAR 306. It is made on the basis of polyurethane resins, an organic solvent and additional modifying components. The adhesive composition is one-component, it is used in the conditions of shoe production. Well established among specialists who are engaged in work with the skin. Quite often, this composition is acquired by private consumers, too, you can follow their example.
Positive feedback
Clay "Desmokol" proved to be excellent in the production and repair of shoes. It is able to reliably and quickly combine different materials, so it is often used when gluing the upper part of the shoe, which is made of leather and fabric. In this case, the sole can be made of:
- thermoplastic;
- polyvinyl chloride;
- polyurethane;
- rubber.
According to users, the described mixture can be used to improve adhesive properties in the direct casting of polyvinyl chloride soles. The composition can be used for bonding oil thermoplastic elastomer and greased skin. Consumers like that this glue can also be used to connect the following materials:
If we compare with other adhesive compositions, then Desmokol glue has higher strength and reliability. According to consumers, it has moisture repellent properties and ductility. After drying, the mixture remains colorless. Buyers like that the product can be purchased in different conditions and packages, among them:
- 50 ml tubes;
- 20-liter metal barrels;
- liter cans;
- 200 liter barrels
On sale, you can find glue in the form of granules, the last of which, as users emphasize, must be diluted independently with a solvent. When preparing the mixture, the quality of the glue will depend on how pure acetone is used. This also applies to other solvents.
Reviews of storage features and recommendations for safe operation
Glue "Desmokol" must be stored at a temperature ranging from +10 to +25 ° C in a sealed package. Consumers especially emphasize that the composition should be away from heating appliances. The mixture will retain its quality for 12 months after manufacture.
If you want to protect yourself, you must follow the manufacturer's recommendations during operation. From the instructions you can find out that the mixture is characterized by high combustible properties, because it is created on the basis of solvents. Work with the composition must be carried out away from sources of open fire. In this case, the room should be well ventilated.
User's manual
"Desmokol" - glue, before using which it is necessary to prepare the surface. To do this, it is cleaned of dust and dirt and rid of old glue. The working surface is processed with sandpaper and degreased. On the two parts that you plan to connect, you need to apply the composition with a thin layer and leave it for 5 to 10 minutes to dry the glue. When absorbing the mixture, apply it again and wait a few minutes again. The glue should grip a little and form a glossy film that does not stick to the fingers.
"Desmokol" - glue for shoes, which in the process of use involves the use of an industrial hair dryer. The latter can be replaced by another heating device. The surface prepared by the above technology must be warmed up to 80 ° C, and then close the two parts as tight as possible. If the glue is of high quality, then it should provide a strong connection that does not require the use of a vice or clamps. Sometimes masters use some other load for additional compression. Use shoes for the intended purpose after 24 hours.
How to dilute and how to pour glue
Desmokol polyurethane adhesive can be poured from a metal can or canister into any plastic bottle. However, for storage, the container must be tightly closed, this will create additional pressure inside. The bottle will not burst, because the pressure is not very high. If you purchased granular glue, then pure acetone can be used to dilute it. Before use, mix the ingredients in a ratio of 1 to 10. This indicates that the Desmokol SAR 306 glue should be used in a volume of 30 g, for which 300 ml of acetone will be needed.
After reading the instructions, you will be able to understand that the manufacturer recommends dissolving the mixture at an ambient temperature of 25 to 30 ° C. To dilute the granules, you need to pour acetone and leave the mixture in this state for a period of 6 to 8 hours. The granules swell, as a result, it will be possible to obtain a heterogeneous transparent composition. Glue polyurethane "Desmokol" for shoes in the next step should be mixed to a homogeneous consistency.
Specialist advice
There is a trick that only experienced shoemakers know. If you plan to glue products that during operation will be constantly exposed to moisture, mechanical stress or temperatures, then the Desmodol additive must be added to the ingredients of Desmokol glue. Its amount should be approximately 7% of the total glue volume. The resulting mixture will be ready to provide thermal stability and strength.
Are there any analogues
If you could not find the described glue on sale, then you can try to find analogues. One of them is Nairit, which is made on the basis of artificial polychloroprene rubber. The ingredients include resins and crosslinking components, as well as organic-based solvents. This mixture is also quite popular among shoe makers.
The composition is used to connect the sole and upper part of the shoe. This glue has proven itself when gluing puffs and heels to the soles. On sale you can find another glue created on the basis of polyurethane. I-900 can act as a one- or two-component mixture. Glue well resists exposure to:
- oils;
- solvents;
- acids;
- moisture.
In the conditions of shoe production, the mixture is used for bonding rubber, thermoplastic, polyurethane, polyvinyl chloride soles. The latter can be made of artificial or genuine leather.
Conclusion
Glue "Desmokol" is quite common in narrow circles. It allows you to achieve a positive result, if you properly prepare the surface. It should be cleaned and degreased, during which gasoline or acetone is usually used. After connecting the elements, their surface can be rolled with a roller, this will ensure uniform bonding and distribution of glue. The key role will be played not by compressive strength, but by complete drying in a calm state.
