Glue "Uranus": composition and method of application

Today the market has a wide range of all kinds of adhesives. Each type has a certain strength of adhesion, setting time, strength of the seam. Specialists have developed recommendations for the use of various adhesives. Among a wide variety of types of adhesive products, the adhesive "Uranus" is very effective.

Product Representation

The product is an adhesive mass for household purposes. The glue "Uranus" is contained in a special metal tube. It is used in cases where it is necessary to connect polyurethane and rubber materials, products from plexiglass, any kind of plastic, thermoplastic and leather (natural and artificial). The glue is made of synthetic urethane rubber Desmocoll, which is soluble with organic solvents. The composition includes ethyl acetate and acetone.

Gluing

One of the effective methods of joining parts used at the time of product assembly is gluing. The connection with the use of adhesive compositions, unlike the mechanical ones, does not damage the products, since it does not penetrate the material. With adhesive bonding, the load is evenly distributed over the entire area. When mechanical, it concentrates at the point of attachment. This can adversely affect the external design of the product: often it is deformed.

The technology of gluing is widespread in the electronic, automotive, aerospace, construction and woodworking industries. In addition to industry, the wide application of glue "Uranus" got And in everyday life. It is effective for repairing shoes (they can be glued sole or heel), leather products (fixing bags, belts), household and office equipment.

Glue "Uranus" due to the high index of adhesive capacity 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 special spatula.

Seam features

Clay "Uranus" Characterized by elasticity and high moisture resistance. When the bonded parts get wet, the bond strength decreases by only 20%. When using this glue a seam is formed, which has no color and is almost invisible. The seam has high elasticity indices, which have a positive effect on the physical and mechanical properties of the products to be bonded.

How to apply "Uranium" glue? Operating and safety instructions

This product is mainly used in everyday life. Effective adhesive "Uranium" for PVC, synthetics, household items. It can also be used to repair shoes. The main thing is that when working with this glutinous mass, it is necessary to fulfill a number of conditions prescribed by the instruction:

• The air temperature should be at least 17 degrees.
• Humidity should not exceed 80%. Otherwise, there is a decrease in reliability and strength of the connection.
• Glue "Uranus" (PVC, boats and shoes) is not intended for polyethylene and metal products. This is due to the low adhesion of the adhesive with such surfaces.
• Before working on the surface of the joined products, thoroughly degrease and clean.
• Glue for polyurethane "Uranus" Can be used by two methods - cold and hot.
• While working with this glue, you need to remember that it is safe for a person when it dries, as it becomes a regular polymer. In its original form, it is very toxic and fire-hazardous. Therefore, it is necessary to work with this glue in well-ventilated rooms where smoking is forbidden and heating appliances with an open spiral are used.
• It is also important to protect the eyes and skin from getting into this mixture. To work with glue "Uranus" it is recommended to use personal protective equipment: protective goggles and gloves. If the product has got on the skin, it should be washed off with acetone. After this, the affected area should be treated with a large amount of water.

Where can I buy, how to transport and store glue "Uranium"?

Buy in Moscow This product can be found in building stores or ordered online. To transport this glue it is desirable to observe the appropriate temperature regime, since "Uranium" is able to crystallize - become a gelatinous mass, not suitable for use. Optimal for him is the temperature from -30 to +30 degrees. Return the contents of the tube to a condition suitable for use, it is possible, if several days the glue will stay at room temperature.

"Cold welding"

The principle of this method is to apply the adhesive mass to the surface of the products to be joined together, and then to press them tightly. The pressing time should be at least eight hours. This method gives the maximum strength of the connection after 24 hours. According to the users of the networks, by the method of "cold welding" it is perfectly possible to repair rubber boats. But it will not be enough to glue PVC. For this material, warm-up and thorough rolling are necessary. When they are used, the adhesive "Uran" for PVC is very effectively applied. Feedback about this product confirms its high quality. Use this substance can also be used to glue the sailing cylinders of the catamaran and even the holders of the oars.

Hot gluing

This method involves preheating the joined products to 90 degrees, after which the glue is applied to the surface, and the products themselves are tightly pressed against each other. Compression time is one minute. Hot gluing is more effective, since the maximum strength is reached after five hours after the start of work.

Products on polyurethane basis

Polyurethane adhesive Uran Characterized by great strength, which is able to withstand the maximum load. This quality is very in demand in construction and repair work, where decorative products from polyurethane are widely used. Among them, plinths and polyurethane stucco are considered the most common today in the construction market.

Ceiling baseboards can have different colors, texture and shape, and the glue "Uranus" is able to provide a strong and durable connection. For stucco professional finishers recommend the use of two separate types of glue paste. One of them is intended for docking of separate parts, and the other is for connecting already finished composition to the surface. In addition to "Uranium" for these purposes, you can use such adhesive compounds as "Moment" and "Europlast".

Advantages of polyurethane adhesive products

Adhesives produced on the basis of polyurethane, are characterized by ease of use and the ability to connect different materials. Polyester and isocyanate are used for making glutinous masses of this group. Thanks to them, the adhesive has a high adhesion to many materials.

The most common adhesives

Of the entire polyurethane group, the most popular are two-component glue weights. 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 inherently very toxic. Therefore, it is recommended to use biuret and aminomides-blocked isocyanates as the hardener, which, as a result of heating, are able to generate isocyanates necessary for the hardening of the film. These adhesives can be operated 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 solvent in the adhesive composition, it is necessary to test the viscosity, which has a polyester base. The higher it is, the more solvent should be added to the formulation.

Organosoluble, or one-component adhesive

Hardening in "Uranus" can also occur due to the humidity of the air. The company "Novbytchim" has developed and produces such an option for adhesive mass. The isocyanate groups contained in it, as a result of the interaction with moisture, which is contained on the surface of the parts to be glued, are converted into a gel. With the help of tertiary amines, available in the composition and performing the functions of catalysts, the curing process is faster. Adhesion and strength of the compound increases if an isocyanate hardener is added to the adhesive. Also, this glue can be used without additives.

What can be needed for gluing the boats?

One of the most pressing problems requiring glue application is the need to eliminate a cut or hole in a rubber boat.

Before you start, you need to get the following materials:

• Acetone. Effective for degreasing surfaces on which there should be no contaminants. Acetone, softening the material, removes all dirt. In the absence of acetone, alcohol or gasoline can be used.
• Building hair dryer. Rubber boats are glued hot. It is recommended to use a hairdryer for this. With its help, the place on the surface warms up at the point where the connecting seam is located. It is important to use only a hairdryer for warming up. The use of an open fire source is not recommended.

• Roller. It is necessary for smoothing wrinkles and eliminating air bubbles.
• Hardener. Performs a hardening additive. Recommended hardener brand "Izr-021". It is added in small doses to the adhesive composition. Before using the finished product, it is recommended to test it on a small piece of material.
• Nylon thread. It is necessary to sew large cuts or holes.

Sequencing

• The work begins with a survey. It is necessary to identify all the damages on the surface of the boat. 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 pumped and placed on the water. In the formed places, you should insert matches. Consider at the same time and places where there are abrasions and delaminations.
• Preparation of patches. They should be rectangular in shape and have round edges.
• Surface treatment with emery. The presence of a roughness on the surface is positive for setting.
• Application of glue. This process is performed in two stages. First, a thin layer is applied, and after half an hour, the second layer is laid on it, onto which the patch is glued. It is necessary to level the surface in time and remove the formed bubbles until the "Uranium" glue has completely dried up. Reviews Users confirm the high efficiency of the hot gluing method. The authors recommend using a rubber hammer instead of rolling. The nailed down places with it are held very firmly.
