Advantages and disadvantages
Nairite glue is a universal and very high-quality product, this is its main advantage. It contains only low-toxic substances, and glued products can be used without fear. Other advantages:
- high temperature resistance;
- elasticity, flexibility, plasticity even with decreasing temperature;
- connection reliability due to deep penetration into materials;
- resistance to water, salts, acids;
- ability to operate at low temperatures;
- preservation of properties during temperature changes.
The material is convenient to use and easy to use. The downside is the drying time - it is slightly higher than that of a number of analogues. But this allows you to calmly place the parts to be glued and have time to correct any flaws. The product does not need to be heated before application and gluing - a “cold method” of application is possible. After drying, it does not deform even the thinnest leather, so it can be used on expensive shoes.
Release form

Adhesive “SAR 306” Thermoactive, polyurethane (1 kg, black)
Attention!
According to the Decree of the Government of the Russian Federation dated January 19, 1998 No. 55, household chemical goods are not subject to exchange or return.
SAR 306 adhesive
is a thermoactive polyurethane adhesive with good resistance to high temperatures. It is intended for leather goods production, but many people use it for reupholstering interiors. Apply with a brush or spatula; to use in a spray bottle, dilute the glue with Molecule solvent.
● Manufacturer KENDA FARBEN (KENDA FARBEN) Italy. ● Consumption of 1 can is approximately 3-5 sq.m. with one-sided single-layer application. ● The adhesive works in the temperature range from -40 to +80 °C ● After application to both surfaces to be bonded and drying, the glue is activated with a hair dryer at a temperature of about +80 °C, the temperature is set on the hairdryer from 150 to 600 °C, and the glue is applied to the surface, warms up from a distance of 5 to 50 cm from the nozzle; the distance from the hair dryer nozzle to the adhesive layer and the temperature of the hair dryer are selected in such a way as not to burn the material and at the same time activate (liquefy) the glue.
APPLICATION OF GLUE:
● Apply SAR 306 adhesive to carefully prepared surfaces and allow to dry for 15-20 minutes at room temperature. Reactivate at 70-80 °C with a hairdryer. Quickly connect and press under pressure of 4-6 kg/cm2 for 10 seconds. Final bonding occurs after 24 hours. ● It is advisable to degrease the working surface with Molekula thinner-cleaner. ● Adding 3-5% Kendor S activator to SAR 306 adhesive can improve the adhesion of any surfaces and, in particular, all difficult-to-glue materials that have a high amount of plasticizers in their structure, such as SBR-TPR-PVC-PU-PA-ABS, fatty leather , HIIYTREL, etc. ● Use glue at a temperature not lower than +18°C. If the product is stored in a cold room, it is necessary to bring the temperature of the glue to +18°C before starting work. ● Solvent content in accordance with existing standards. We ignite.
If the working surface is plastic marked PP/PE, then to stick the material onto such a surface you need to use polychloroprene adhesive SAR 30-E.

Instructions for use
To ensure reliable gluing of parts, it is necessary to first clean the bonded surfaces from dirt, dust and material residues. After this, the surfaces are cleaned with sandpaper and treated with acetone or alcohol. There are three different ways to glue surfaces using Desmokol glue .
The easy way. A thin layer of adhesive is applied to the surfaces to be glued, after 2-3 minutes the operation is repeated, after which the surfaces are pressed against each other with maximum force.- Wet method. The surfaces are moistened with water, after which a thin layer of Desmokol is applied and the parts to be glued are placed under a press or clamped with clamps.
- With heating of the bonded surfaces. The surfaces coated with adhesive are left for 10 minutes, after which they are heated with a hairdryer to 80 °C and also clamped with clamps.
Characteristics of Desmokol
The finished dried seams remain transparent and moisture resistant. Desmokol glues wet surfaces (no more than 25%), this confirms its effectiveness in repairing inflatable rings, mattresses, boats, and bicycle inner tubes. The resulting adhesive film is not afraid of severe frosts and ensures the tightness of the coating during temperature changes.
The glued joint remains elastic and strong even under mechanical loads. You can adjust the position of the parts until the seam is completely dry. If parts are glued indoors, it must be ventilated or have a working ventilation system.
When working with polyurethane substances, they have a slight effect on the skin of the hands and may irritate the mucous membranes. The components do not cause an allergic reaction, but in case of direct contact, it is necessary to rinse everything off with running water and consult a doctor if there is redness and burning. If Desmokol is used constantly, for example, in industry, then the use of a respirator and gloves is mandatory. The room itself needs to be ventilated more often.
