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 main component of the adhesive is cyanoacrylate

The main component of the adhesive is cyanoacrylate

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%.
At too cold or dry atmosphere is necessary to use the adhesive activator

At too cold or dry atmosphere is necessary to use the adhesive activator

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.

Cyanoacrylate adhesive may be one- and two-component

Cyanoacrylate adhesive may be one- and two-component

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.

Consumption of cyanoacrylate adhesive per square meter of only 30-50 g

Consumption of cyanoacrylate adhesive per square meter of only 30-50 g

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).
Most solid compound obtained in the humidity condition of from 40 to 70%

Most solid compound obtained in the humidity condition of from 40 to 70%

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 ;
  • through 100-gram package - 2-3 ;
  • 20 g of a tube - approximately 0.7 .

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.
