Cyanoacrylate Adhesive varieties, specifications

During installation and assembly of the various parts made of polymers and plastic, often used glue. This is the optimal embodiment in the case where the presence of additional holes in the part makes the compound more vulnerable and subject to various influences. One of the best compositions - a cyanoacrylate adhesive. This publication contains detailed information on this matter.

CA glue: characteristics of the substance

Cyanoacrylate adhesive has a high level of adhesion to a variety of substrates. All this is possible thanks to the copolymers, which are part of any cyanoacrylate component adhesive. Each manufacturer has its own unique adhesive formulation, as well as the secrets of its production. This information is kept secret from competitors. The main feature of these adhesives - the ability to hold the surface together perfectly, even materials that vary in quality and structure. These reagents are also characterized by their long life.

The base includes a cyanoacrylate adhesive, and acid derived from it. They can reach up to 99% of the total. The adhesive composition also includes plasticizers and thickeners which give it additional properties such as water resistance, heat resistance, adhesion. In order to better adhesive shifted vibration abietic acid is used in conjunction with glycerin.

Cyanoacrylate for bonding the solid, porous and elastic even surfaces which may be in any position. The main active component of the adhesive may be different monomers:

• ethyl excels at a wide variety of materials and virtually no wear;
• methyl ester promotes adhesion of metal and thermoset;
• butyl ether - an ideal material for use in the medical field and special equipment;
• propyl ester is sometimes necessary for the bonding of different metals and elements exposed to high temperatures;
• compositions based on alkoxy-esters are without odor, but this is achieved by lowering the reliability of the compounds is 20-30%.

The operating principle of cyanoacrylate based adhesive is that it starts to set when exposed to ordinary water or a weak alkali. When bonding a very thin layer of material curing process can take place without the participation of cyanoacrylate adhesive activator.

Useful advice! Activator adhesive should be used in dry or too cold atmosphere. It is particularly effective during bridge large gaps or processing of non-reactive materials. That the surface remains smooth and flat, you need to carefully adhere to the recommended distance for spraying. It must be remembered that some types of activators may adversely affect the thermoplastics and lacquerware. It is necessary to bear in mind that, together with an activator and primer should be used.

Cyanoacrylate Adhesive varieties substance

One-component transparent cyanoacrylate adhesive is characterized by a very rapid polymerization under pressure. This composition after drying, forms the connecting member between the thin, but, durable film. These characteristics make the glue optimal solution for metal and synthetic materials, including parts for medical equipment.

The most commonly used second two-component adhesive in the home. Liquid compositions, due to the lower viscosity, able to close the gaps to 0.05 cm, and more viscous materials can seal the gap to 0.03 cm. Clutch rubber and leather items, as well as products made of wood shavings perfect two-component adhesives.

Important! The most reliable and strong connection is formed in the humidity of 40 to 70%. If it is reduced to 30% or less, the seam will be very long to solidify, and if the humidity is above 80%, the adhesive polymerization process is extremely fast, which reduces the reliability of the joint. Reducing or increasing the temperature by 10 degrees slow down or accelerate the adhesive coupling process twice. Optimum conditions for use with cyanoacrylate - from 20 to 24 ° C.

Tsianoakrilatovy glue: technical characteristics and properties of the adhesive

At this time, the production of cyanoacrylate glue, which glues all tightly, engaged in many well-known companies. The main characteristic of the substance - is a high level of adhesion to a huge variety of surfaces, including wood, glass, metal, plastic and rubber. It should be noted that superglue adhesive absolutely not affected by substances such as water, oil, gasoline, as well as various alcohols.

Cyanoacrylate second adhesive is functioning perfectly at the gaps smaller than 0.1 mm. It can be used for connecting closely adjacent parts. There are reactants with high viscosity which is optimally suited for operation with a gap of about 0.25 mm. Consumption of such adhesive per square meter is about 300 grams If you want to eliminate a gap large size, it is usually used cyanoacrylate adhesive composition Cosmofen or CA-4.

With regard to the technical characteristics of cyanoacrylate glue, they are determined by the scope of the matter. Let us examine them in more detail:

1. Physical state. Cyanoacrylate based adhesive has a thick consistency and has a high viscosity. Typically, crystalline substance, but there may be other options - it all depends on the manufacturer.
2. Packaging. Clay is made in a completely sealed container. Supplemented packing instructions for use describing the precautions when working with this substance.
3. solidification mode. In low humidity conditions at room temperature bonding process is carried out in a few seconds. In the case of high humidity, this process is performed almost instantaneously.
4. Operating temperature range. All one-component and two-component cyanoacrylate adhesives are able to withstand a temperature of from -60 to +80 ° C. There are special modified heat-resistant compounds that may briefly maintain its characteristics even at elevated temperatures (up to +250 ° C).

The compound formed by the adhesive is obtained a reliable and durable, and resistant to environmental conditions and mechanical stress. After opening a sealed vial experts do not recommend to keep stuff for a long time. This is due to the fact that in these conditions are violated physical and engineering properties of the adhesive, it may become brittle and fragile after polymerization.

It should also be noted the small consumption of cyanoacrylate adhesive per square meter - it is only 30-50 g Therefore, using the dispenser, the adhesive can be processed:

• using containers of 400 ml - about 13 m²;
• through 100-gram package - 2-3 m²;
• 20 g of a tube - approximately 0.7 m².

It is interesting! The more liquid the consistency of a cyanoacrylate adhesive, the better it sticks together solid surface. Completely transparent adhesive is ideal for glass structures. Glue precious metals using cyanoacrylate adhesive impossible.

Cyanoacrylate adhesives: advantages and disadvantages

Cyanoacrylate adhesives have many positive characteristics, as well as disadvantages. Primarily they are positioned as versatile compounds that can be connected together even different in structure materials and substances. The advantages also include such qualities:

• difficult to use at high temperatures;
• forbidden to use for bonding PTFE, polypropylene or silicon surfaces;
• glue is unsuitable for connecting elements, which joints are in use receive a large load to fracture;
• It is not recommended to fill a similar adhesive large gaps.

It should be noted that a junction glued cyanoacrylate glue, is destroyed at temperatures above 100 ° C.

Furthermore, a detrimental effect on the glue acetone. However, most other solvents are not afraid of cyanoacrylate. These compositions adhere perfectly to a variety of surfaces and costs are very economical. The substance has no allergic properties and is a dielectric.

It is interesting! The cost of cyanoacrylate adhesive is quite high, in addition, to work with him to be exclusively in the gloves. In case of contact with a cotton cloth can be ignited.

That glues cyanoacrylate adhesive: scope

Most of superglue cyanoacrylate and its derivatives, and it is supplemented with various additives - plasticizers. It is thanks to them that there are several main areas of use of such an adhesive. Let's look at that glue super glue based on cyanoacrylate.

The second dissolve cyanoacrylate glue and how to remove the excess from the surface

While working with adhesives based on cyanoacrylate is likely to spill the adhesive on the surface, which do not require gluing. This usually occurs because of the ill-prepared workplace. Therefore, the question of what to remove cyanoacrylate adhesive is extremely relevant. Unfortunately, at this time it has not yet devised a means which enables to dilute or dissolve the adhesive to further remove it, without damaging the surface. Because you never know what to launder cyanoacrylate adhesive from the surface, it is necessary to work with caution.

Remove unnecessary adhesive surface is possible, but only by mechanical means. You can try to just scrub the stain. This can be done, if the material is durable and does not break. Perform removal need a sharp knife, but the work must be handled carefully and gently so as not to compromise the integrity of the surface. Adhesive residue can try to scrub with white spirit. This allows the smaller particles dissolve in the tissue and thus remove particulate adhesive layer.

The cyanoacrylate adhesive wash with hand or skin? In this case, useless to look than to dissolve cyanoacrylate adhesive. Wash off, peel or scrub the substance can not be, since it will be removed with the human skin. The usual solvent for paints and varnishes, gasoline, kerosene, vegetable oil and alcohol to try pointless. The best option - is to wait a few days until the adhesive starts to peel yourself, only then you can start to remove the glue without any harm to the body.

In should be very carefully as purifier can also try to acetone, but with the help remove the adhesive composition from the skin, plastics and other organic surfaces. Before dissolving the second adhesive, it is necessary to remember that cyanoacrylate is inert, which means that in no way reacts with substances such as gasoline, oil, ethanol, and many other common solvents.

Important! The instructions for use of the SA-500.200 cyanoacrylate adhesives and many other similar products mentioned "Dimexidum" as a means to remove the glue. This substance is extremely toxic, has an unpleasant smell, so it is better to think before you scour the cyanoacrylate adhesive composition of this.

Tips and advice on the use of "Moment" cyanoacrylate adhesive

Working with cyanoacrylate glue, it is important to strictly adhere to the regulations and rules of personal safety. All gluing steps must be performed only in a well ventilated place, as glue couples They are very toxic, toxic, and violation of operating conditions can cause great harm to health. Cyanoacrylate adhesive must not be exposed to the skin and mucous membranes.

Before using a reagent necessary to read the instruction, which is in the package, because different types of adhesive designed for bonding of certain surfaces. It is important to pay attention to the specified terms and conditions of storage, as well as the features of the application.

The process of using the adhesive is as follows:

1. Necessarily need to be cleaned and dried surfaces to be bonded.
2. It is necessary to uniform and homogeneous layer of adhesive is applied to one of the connected parties.
3. For better clutch parts for some time fixed, for the best effect, you can put them under the press.

Important! While working with cyanoacrylate glue to be applied protective equipment for the skin and mucous membranes: gloves, goggles, mask. Chemical components are harmful to the human body: if it enters the body, they corrode. It is undesirable to inhale the vapors of glue, as they are toxic. That is why using a substance, it is imperative to adhere to precautionary measures.
