Glue bright: purpose and application

To produce high-quality footwear, a wide variety of connecting materials are used. The method of simultaneous stitching and sizing prolongs the service life of the products. Najrit glue is one of the most reliable and versatile materials, which is most often used for the production and repair of shoes.

Characteristics

This substance is used for gluing materials such as leather, rubber, foam rubber, wood, plastic and fabric.

Najrit glue has a lot of useful properties:

- High thermal stability and strength. Only low-toxic substances are found in the composition. Chloroprene rubber resin - the main component, also in the composition there are synthetic additives, non-volatile solvents and thermal vulcanizers. It is thanks to these components that the adhesive is characterized by such high qualities.

- It is sufficiently resistant to moisture, acids and petroleum products. Shoes made with the use of nairitic glue will serve for a long time even in conditions of unfavorable environment (rain, snow, wind, frost, etc.). The place of connection literally repels water and does not allow it to be absorbed. And so the feet will not get wet, regardless of the weather conditions. Many shoesmakers process the seams with glue that seals the junction and prevents moisture from entering the product. With its help repair rubber boats, diving suits for divers and car cameras.

- The connection retains flexibility even at low temperature conditions. The seam treated with this substance retains plasticity in any weather and does not allow the product to crack.

- The mixture is fairly simple to use. There are two methods of using it: hot and cold. Both are reliable, but the cold is a little easier, because special tools are needed for hot work.

- High adhesion qualities. The adhesive provides excellent grip even when working with porous materials.

- For a long time it does not deteriorate. Does not lose its quality even in the open state (but not more than 65 minutes).

Methods of application

As already mentioned, the glue can be used in two ways.

Hot:

- The first stage is preparatory work, which involves cleaning the surface of dust and dirt. After that, it must be degreased with alcohol and dried.

- Application of glue. The first layer must be thin. After 15 minutes, you need to apply a second one. After that, the products are dried in a ventilated room or on the street 35-45 minutes at a temperature of not less than +20 ° C.

- Warming up. This stage involves heating the surfaces to a temperature of about 100 ° C. Then the parts to be pressed must be pressed against each other.

- The final stage. Products should be left for 6 hours, after which they can already be used.

Cold method is suitable for materials that do not have thermostable qualities: polymers, foam rubber or cardboard:

- The first stage is the cleaning of products.

- Application of glue. Nairitic glue is applied on the surface with a thin layer, then they should be dried for about 10 minutes at a temperature of not less than + 22 ° С.

- Gluing. Strongly press the surfaces together and hold for 5-8 minutes.

- After that they should be left in a vertical position for 24 hours. Done.

Storage Rules

Keep the mixture in the factory container, it is very important not to damage it. Warranty period - no more than 1 year at a temperature from +6 to +22 degrees away from open fire. Glue shoe naimitovy can thicken even if all the rules, but it's not scary. It can be dissolved with ethyl acetate and high octane gasoline. The composition is prepared simply, it is necessary to mix glue and solvents in the same proportions. The main thing - gradually pour them into the glutinous mixture and mix thoroughly.

When applying, it is important not to forget that the mixture is flammable. To conduct work should be away from open fire, smoking near an open can with liquid is prohibited. Nairit glue has only low-toxic substances in the composition, but it is necessary to work with it only in buildings that are well ventilated.

If the glue is transported at a low temperature, the viscosity index rises. However, this can be corrected, leaving it for several hours in a warm building. After that, his qualities are restored.
