Today on the market there is a wide range of various adhesives. Each type has a specific adhesion force, setting time, and joint strength. Experts have developed recommendations for the use of various adhesives. Among a wide variety of types of adhesive products, Uranus glue is very effective.
Product Presentation
The product is an adhesive mass for domestic use. Uranus glue is contained in a special metal tube. It is used in cases where it is necessary to combine polyurethane and rubber materials, plexiglass products, any types of plastic, thermoplastics and leather (natural and artificial). Desmocoll synthetic urethane rubber adhesive, which dissolves with organic solvents, is produced. The composition includes ethyl acetate and acetone.
Gluing
One of the effective methods of joining parts used during assembly of the product is bonding. The connection using adhesive compositions, unlike mechanical, does not damage the product, since it does not penetrate the material. With adhesive bonding, the load is evenly distributed over the entire area. With mechanical, it concentrates at the attachment point. This can adversely affect the appearance of the product: its deformation is often observed.
Bonding technology is common in the electronic, automotive, aerospace, construction and woodworking industries. In addition to industry, widespread use of glue "Uranus" got and in everyday life. It is effective for repairing shoes (they can stick a sole or heel), leather products (repairing bags, belts), household appliances and office equipment.
“Uranus” glue due to the high adhesive ability provides a gentle method of bonding - the product does not deform, and the colorless seam does not spoil the appearance. Aesthetics of such a connection is possible if you use a brush, roller or a special spatula.
Seam Features
Uranus glue characterized by elasticity and high moisture resistance. When wet glued parts, the bond strength decreases only by 20%. When using this glue, a seam is formed that is colorless and almost invisible. The seam has high elasticity, which positively affects the physicomechanical properties of glued products.

How to apply glue "Uranus"? Operation and Safety Instructions
These products are mainly used in everyday life. Glue "Uranus" is effective for PVC, synthetics, household items. It can also be used to repair shoes. The main thing - when working with this adhesive mass, it is necessary to fulfill a number of conditions prescribed by the instruction:
- Air temperature should not be lower than 17 degrees.
- Humidity should not exceed 80%. Otherwise, there is a decrease in the reliability and strength of the connection.
- Uranus glue (PVC, boats and shoes) is not intended for polyethylene and metal products. This is due to the low adhesion of the adhesive to such surfaces.
- Before starting work, the surfaces of the connected products should be thoroughly degreased and cleaned.
- Glue for polyurethane "Uranus" can be used in two ways - cold and hot.
- When working with this glue, you need to remember that it is safe for humans when it dries, since it becomes an ordinary polymer. In its original form, it is very toxic and fire hazard. Therefore, you need to work with this glue in well-ventilated areas in which it is forbidden to smoke and use heating appliances that have an open spiral.
- It is also important to protect the eyes and skin from contact with this mixture. To work with glue "Uranus" it is recommended to use personal protective equipment: goggles and gloves. If the product gets on the skin, it should be washed off with acetone. After this, the affected area should be treated with plenty of water.
Where can I get, how to transport and store Uranus glue?
Buy in Moscow this product can be in hardware stores or ordered online. To transport this glue, it is advisable to observe the appropriate temperature regime, since Uranus is able to crystallize - to become a jelly-like mass, not suitable for use. The optimum temperature for it is considered to be from -30 to +30 degrees. You can return the contents of the tube to a condition suitable for use if the adhesive remains at room temperature for several days.
"Cold welding"
The principle of this method is to apply the adhesive mass on the surface of the products to be joined together, followed by their tight pressing. The pressing time should be at least eight hours. This method gives maximum strength after 24 hours. According to netizens, rubber boats can be repaired quite qualitatively by the “cold welding” method. But it will not be sufficient for gluing PVC. This material requires warming up and careful rolling. When using them, Uranus glue for PVC is very effectively applied. Reviews of this product confirm its high quality. You can also use this substance for gluing sailing catamaran cylinders and even oar holders.
Hot bonding
This method involves preheating the connected products to 90 degrees, after which the adhesive is applied to the surface, and the products themselves are pressed tightly against each other. Compression time is one minute. Hot bonding is more effective since maximum strength is reached after five hours after the start of work.
Polyurethane Based Products
Polyurethane adhesive "Uranus" characterized by high strength, which is able to withstand maximum load. This quality is very in demand in construction and repair work, where polyurethane decorative products are widely used. Among them, the most common today in the construction market are skirting boards and polyurethane stucco moldings.
Ceiling skirting boards can have various colors, textures and shapes, and Uranus glue is able to provide their strong and durable connection. For stucco molding, professional finishers recommend using two separate types of adhesive. One of them is intended for joining of separate parts, and another - for connection of already finished composition to a surface. In addition to Uranus, adhesive compounds such as Moment and Europlast can be used for these purposes.
Advantages of polyurethane adhesive products
Polyurethane-based adhesives are characterized by ease of use and the ability to combine various materials. For the manufacture of adhesive masses of this group, polyesters and isocyanates are used. Thanks to them, the adhesive has high adhesion with many materials.
The most common adhesives
Of the entire polyurethane group, the most popular are two-component adhesive masses. They consist of a polyester base and a hardener, which includes an isocyanate group. Before using such an adhesive, its components are mixed. They can work for one to three hours. The adhesive film hardens after two days at room temperature. It should be remembered that the isocyanate group is very toxic in nature. Therefore, it is recommended to use biuret and aminomides as blocked hardeners - blocked isocyanates, which, as a result of heating, can generate isocyanates necessary for hardening the film. Such adhesives can be used for twelve hours. In addition, they are less toxic.
Preparation of two-component glue
Biuret and isocyanate for sale should already contain a solvent. In order to determine the presence of a solvent in the adhesive composition, it is necessary to test the viscosity that the polyester base has. The higher it is, the more solvent should be introduced into the composition.
Organically soluble, or one-component adhesive
Hardening in Uranus can also occur due to air humidity. The company "Novbytkhim" has developed and produces this version of the adhesive mass. The isocyanate groups contained in it are converted into gel as a result of interaction with moisture, which is contained on the surface of the parts to be bonded. With the help of tertiary amines present in the composition and acting as catalysts, the hardening process is faster. Adhesion and bond strength are enhanced if an isocyanate hardener is added to the adhesive. Also, this glue can be used without additives.
What may be needed for gluing boats?
One of the most pressing problems requiring the use of glue is the need to eliminate a cut or hole in a rubber boat.
Before you begin, you need to acquire the following materials:
- Acetone. Effective for degreasing surfaces on which there should be no contamination. Acetone, softening the material, removes all dirt. In the absence of acetone, alcohol or gasoline can be used.
- Construction hair dryer. Rubber boats stick together hot. To do this, it is recommended to use a hairdryer. With it, a place on the surface is warmed up at the point where the connecting seam will be located. It is important to use only a hairdryer for warming up. The use of an open source of fire is not recommended.
- Roller. It is necessary to smooth wrinkles and eliminate air bubbles.
- Hardener. Performs a hardening additive. The hardener of the Izur-021 brand is recommended. It is added in small doses to the adhesive. Before using the finished mass, it is recommended to test it on a small piece of material.
- Kapron thread. It is necessary for suturing large cuts or holes.
Sequencing
- Work begins with an inspection. All damage to the surface of the boat must be identified. Attention should be paid even to small holes, since after a while they can form large gaps. To detect all the holes, the rubber boat is inflated and placed on the water. Matches should be inserted into the resulting places. In this case, one should also take into account places in which abrasions and delaminations are observed.
- Cooking patches. They should be rectangular in shape and have round edges.
- Emery surface treatment. The presence of surface roughness is positive for setting.
- Glue application. This process is carried out in two stages. First, a thin layer is applied, and after half an hour a second one lies on it, on which the patch is glued. It is necessary to level the surface in time and remove the resulting bubbles until the glue “Uranus” has completely dried. Reviews users confirm the high efficiency of the hot gluing method. The authors recommend using a rubber mallet instead of rolling. Glued places glued with it help hold very firmly.
