Today's variety of adhesive mixtures is amazing. And among this large number, spray adhesive stands out for its versatility, characteristics and ease of application.
What is spray adhesive
The main feature of aerosol adhesive is the method of application. The adhesive is contained in a can of aerosol, so it is applied quickly and easily, in an even layer, the thickness of which can be easily adjusted both on large surfaces and in hard-to-reach places with just a push on the spray head.
At the same time, aerosol glue is successfully used in working with a variety of materials: wood, metal, plastic, textiles, for gluing smooth and porous surfaces. It provides not only strong, but also flexible connection of elastic materials, can seal leaks.
Fields of application and types of glue in aerosol
Aerosol adhesive spray is used in the manufacture of furniture, advertising structures, insulating materials, construction and finishing works, in the production of artificialfibers, textile industry. In the production and repair of automobiles, it is used to fix upholstery and trim elements, vinyl panels, metal and plastic parts, plastic and fabric are connected without compromising their appearance and joint strength. In many cases, it is easier to use than double-sided tape.
Different types of glue can be used for different materials to be bonded.
There is glue in a can for paper and fabrics. It can be used for temporary or preliminary fixation as it does not leave marks on surfaces. The special adhesive for foil and film, designed for light porous and smooth materials, has the same advantage. If you need to glue polypropylene, polyethylene with wood or metal, use a spray with increased fixation strength. There is also a composition that does not dry out the rubber, does not violate its structure and does not lead to cracking of the material.
There is a separate adhesive for metal and plastic.
In everyday life, it is easiest to use polymer universal glue. It can replace any of the highly specialized species.
Advantage of spray adhesive
Spray adhesive has several undeniable advantages over other adhesive formulations. Firstly, it is easy to work with, no brushes, spatulas, tampons and other improvised materials are needed. Secondly, due to fast drying and good adhesion, there is no need for long-term fixation of materials when gluing. Thirdly, in a sealed aerosolin the container, the composition does not dry out, which means it can be stored for a long time.
Besides, it does not leave stains or marks; you can adjust the width of the jet, and hence the cost-effectiveness of use; has high strength and heat resistance, resistance to vinyl plasticizers, does not destroy the acrylic coating.
Spray adhesive can fix items on window panes when exposed to sunlight. During the gluing process, the surfaces can be moved for several minutes, for example, to align the joint.
How to properly glue
When working with aerosol adhesive, you need to follow a few simple rules that will ensure reliable fixation of materials.
First you need to clean, dry and degrease the surfaces to be bonded. Then, if the cartridge was stored in a cold place, warm it up to room temperature or, if necessary, cool it down to it. Shake thoroughly and strongly just before use, adjust the jet width by turning the spray head, and apply glue to the surface to be glued.
The width of the jet and the thickness of the layer depend on the characteristics of the material. The more porous and heavier it is, the wider the layer is naturally applied, moreover, it may be necessary to apply a second layer after drying for several minutes, and on both surfaces.
Aerosol adhesive is sprayed from a distance of 15-20 centimeters from the surface. The can must be held parallel to the surface, while pressing the sprayer to the end, apply the composition evenly, slowly and slowlystopping.
It will take about half an hour for the glue to dry completely.
So that it does not freeze in the socket, after using the balloon, you need to turn it over, press the sprayer and hold it in this position until the residue comes out.
Store glue in a dry, dark place at a temperature of 5 to 30 °C.
Safety measures and expert advice when working with aerosol adhesive
When working with aerosol glue, you need not only to know how to glue correctly, but also what safety measures to follow. First of all, you need to work in a well-ventilated area and use personal protective equipment, while smoking is strictly prohibited.
If the glue gets on the clothes, then it should be carefully washed, the soiled face or hands should be immediately washed with soap and water.
The cylinder with glue should be stored away from heating devices, separately from oxidizing agents and alkalis, protected from both high and low temperatures and remember that its vapors can ignite from an open fire, and with an explosion.
If there is a break in the work with the spray, then the container must be closed.
Experts say that it is imperative to monitor the expiration date of aerosol glue. You should not use an expired product, even if outwardly it has not changed and fixes surfaces well, because such a connection no longer guarantees high strength. Sometimes it happens that the applied layer of glue does not dry out, remains liquid for a long time,it means that there is no need to wait for a good fix.
Glue brand "3M"
Today, one of the most popular adhesive compositions is aerosol waterproof glue of the 3M brand. The basis of the spray are elastomers, dimethyl ether is used as a propellant. Solvents are cyclohexane, pentane, petroleum distillate, toluene and acetone. With high resistance to water, very low oil and petrol resistance. The operating temperature range of 3M sprays is from -30 to +100 °C. They do not leave marks, materials can be re-glued several times if necessary.
The line of sprays of the 3M brand also includes a polymer universal adhesive, which is used to fix metals, wood, plastics, polystyrene foam, artificial fabrics and much more, and products designed specifically for temporary and permanent fixation of certain types of materials of different thicknesses. All of them have their own numbers and differ in composition, type of solvents, type of jet.
Multi spray glue
This spray adhesive has no analogues, it can fix absolutely everything with a degree of adhesion from weak, when the surface can be easily separated, to very strong.
Its peculiarity is also that Multi spray waterproof adhesive is used in aircraft, ship and automotive industries to solve problems of acoustics and sound insulation. It is also not afraid of dusty surfaces, therefore it is used in finishing works forgluing decorative materials, including flexible ones, onto a concrete base.
Wood, plywood, veneer, stone, concrete, tile, rubber, foil, metal, plastic, cardboard, felt, cork, paper - this is not the whole list of materials that can be glued with Multi spray.
Based on patented rubber components and filled with dichloromethane.
Aerosol glue ABRO
This composition is made in the USA and also enjoys well-deserved popularity. It comes with a nozzle for applying glue in a thin strip on a narrow surface, the spray head for different modes of operation can be rotated in three positions. A professional spray adhesive is produced by the manufacturer - high-strength, very fast drying, but it is not suitable for all light materials, despite the fact that heavy ones stick together almost everything. You can clean it with alcohol or mineral gasoline.
Sprays are available in both general purpose and general purpose sprays that can be used in car repairs and home crafts, although it may ruin the appearance of some painted or plastic surfaces.
For different purposes and tasks, you can choose an adhesive composition, both universal and special, for example, for drawing a pattern on fabric or gluing carpet on a concrete screed. A large selection of well-known brands of sprays allows you to choose the best option for professional or home use.
