Description and purpose of cyanoacrylate adhesive, best manufacturers
Among universal adhesives, cyanoacrylate is considered the best, as it provides reliable fastening of various materials. This tool creates a reliable and long-lasting connection. In addition, cyanoacrylate glue hardens quickly. This tool is based on the substance of the same name, which provides the properties of the product. Therefore, the characteristics of the glue do not depend on the type of manufacturer.
Peculiarities of the cyanoacrylic composition
This glue contains cyanoacrylate (a-cyanoacrylate acid) and modifying additives that increase the resistance to heat and humidity of the compounds created. Some of these formulations further include:
- stabilizers;
- plasticizers;
- thickeners (adjust viscosity);
- polyacrylics and polyvinyl acetate (improve adhesion);
- finely dispersed metal powders (provide electrically conductive properties).
Cyanoacrylate adhesive provides reliable bonding of a variety of materials, including rubber and electroplated surfaces.At the same time, this product does not interact with alcohol, gasoline and other organic substances.
Thanks to this base, the cyanoacrylate glue has the following characteristics:
- transparency;
- viscous consistency;
- shelf life - up to six months;
- curing takes up to 20 minutes at room temperature;
- the strength of the created joints is 8-12 megapascals;
- with constant contact with water, the resistance of the joints decreases.
Cyanoacrylate glue can be applied at temperatures from -60 to +70 degrees. Thanks to some additives, this range widens to +300.
Appointment
Cyanoacrylate glue is used in various fields. This composition is used for joining materials, mainly for household purposes. But in some cases, the adhesive is used to insulate wiring and in the sewing industry.
At home
The cyanoacrylic compound is very popular when it is necessary to quickly restore damaged parts. This instant glue is used for connecting wires, repairing clothes, restoring various objects and for other purposes. That is to say, the scope of this product in everyday life is limited by the properties of the product.
In cosmetology
Due to their ability to quickly set the cyanoacrylic composition, they are used in cosmetology. With this tool, eyelashes and nails are lengthened. However, in cosmetology, a separate type of glue is used, which includes acrylic.
In dentistry
In dentistry, this glue is used to remove small chips on the teeth. In this case, a special composition is also used, which includes additives that do not have a negative effect on the oral cavity and provide increased moisture resistance of the created compound.
To create isolation
Due to a number of additives, cyanoacrylate glue is characterized by increased resistance to heat and moisture.Due to these properties, this tool is used to create insulation (mainly wiring).
Choice criteria
There are a number of factors to consider when choosing the right cyanoacrylate adhesive. In particular, it is necessary to take into account what kind of materials it is planned to use such a tool. In accordance with this criterion, an appropriate adhesive should be selected.
State
Thanks to the cyanoacrylate, the glue has a transparent consistency. The color of the material may vary depending on the type of additives. If after purchase it turns out that the material has a different consistency, the product must be returned.
Pack
Cyanoacrylate glue belongs to the group of fast-drying glues. Therefore, if the packaging is damaged, the composition will air harden within minutes. This means that it is important to check the integrity of the tube when purchasing a product.
Solidification
The rate of curing of the adhesive composition depends on two factors: the characteristics of the components that make up the composition and the environmental conditions. On average, this product dries in 20 minutes at room temperature and 70-80% humidity. If the latter indicator falls below 55%, additional additives will be required, the type of which should be checked with the seller.
Temperature difference
As mentioned earlier, this glue provides a reliable connection at temperatures from -60 to +80 degrees. This is sufficient for most jobs.In cases where the glue is used in harsh conditions (in production), it is recommended to purchase a product with additives that allow the use of this product at temperatures up to +300 degrees.
Review of the best manufacturers
Cyanoacrylate glue is available under different brands. However, there are no striking differences between these products.
Pronto CA-4
Pronto CA-4 is a classic universal cyanoacrylate adhesive. The composition is distinguished by a viscous structure and transparent color.
This tool does not require mixing with other components before use.
interlink
A two-component compound used to bond the following materials:
- rubber;
- leather;
- chipboard;
- MDF.
Interbond contains substances that improve the moisture and heat resistance properties of the joint created. This product is produced in different packaging. The adhesive composition of this brand is characterized by low resistance to open fire. But, unlike other products, Interbond hardens quickly: the material dries in 5 to 7 seconds.
Permabond 791
In terms of drying speed, this glue is comparable to the previous one. However, this composition is mainly used when working with glass, elastic or rigid materials. The components included in the composition provide sufficient moisture resistance at the connection.
Cosmofen
This product is considered the most demanded by consumers. The popularity of the product is due to the fact that Cosmofen is suitable for gluing various surfaces and does not dry out within a month after opening the package.
Kingway Lanxi
A Chinese brand product that has the same properties as other cyanoacrylate adhesives, but costs less.
Taizhou Henco-glue
This product allows instant bonding of surfaces made of different materials.In terms of the combination of properties, this tool is not inferior to the previous one.
Hunan Baxiondgi New Material
This Chinese-made product has the same characteristics as the two previous ones.
How can you dissolve
Due to the fact that cyanoacrylate adhesives provide a fast and reliable connection, the likelihood of errors when using such formulations increases. However, this agent can only be removed from the surface mechanically: wiped with a knife or other object sharp. If the adhesive is based on methyl cyanoacrylate, then water is used to remove the composition. Nitromethane is also used as a solvent. But such a substance is hard to find.
In addition, the adhesive cannot be removed from the hands. If the product comes into contact with the skin, you must wait up to five days. During this time, the glue will peel off naturally.
Advantages and disadvantages
Cyanoacrylic compounds are characterized by the following advantages:
- rapid hardening;
- provides strong and durable connections;
- electrical insulating properties;
- moisture and heat resistance;
- hypoallergenic (allergic reactions are rare);
- suitable for bonding various materials, including porous.
Among the disadvantages of these products, users highlight the following:
- intolerance to mechanical stress (typical for some types of glue);
- cannot be used to fasten joints subject to breaking loads;
- the composition cannot be immediately removed from the skin;
- with prolonged storage, it loses its original properties;
- in contact with a cotton cloth, the gasket may ignite.
Cyanoacrylate formulations are expensive compared to other similar products.
Additional tips and tricks
When working with cyanoacrylate glue, you must use personal protective equipment (gloves, etc.). It is recommended to study the instructions before purchasing. Some types of this product are suitable for bonding specific materials.
