What is cyanoacrylate, and what are the precautions for the use of cyanoacrylate?

Cyanoacrylate, i.e., instant fast-following glue, ingredient cyanoacrylate glue, is a one-component, fast-curing adhesive synthesized through advanced production processes. Cyanoacrylates are versatile, easy to use, have very fast curing speeds, high bond strength, a wide range of bonding areas, and good adhesion to a variety of substrates such as metals, plastics, rubber, elastomers, paper, leather, fabrics, etc.

Cyanoacrylates, also known as cyanoacrylates, cure very quickly on the surface of the material to which they are bonded. Moisture on the surface of the substrate can initiate a curing reaction of the glue. The reaction takes place from the surface of the substrate to the middle of the glue.

Cyanoacrylates are widely used for bonding small parts where fast fixation is required. Due to its limited ability to fill gaps, the bonding process requires a tight fit on the surface to be bonded.

For most substrates, cyanoacrylates have very good adhesion. It has excellent performance in shear strength and tensile strength.

Advantages of cyanoacrylate:Clean and easy to operate.

Extremely fast positioning of the site.

It is widely used for bonding different types of materials, especially rubber and plastics.

High bond strength can be achieved on very small bond surfaces.

Solvent-free. Complex geometries such as snap-fit are not required for the bonding site.

1207 non-whitening instant adhesive has passed the EU ROSH standard testing, is a high-strength one-component instantaneous adhesive specially developed for non-whitening and odorless bonding, with high performance, aging resistance, and is very suitable for continuous production line operation. After bonding, it can withstand high temperature 90 degrees Celsius and low temperature -40 degrees Celsius for a long time. It is mainly used for bonding metals, plastics, ceramics, porcelain, handicrafts, marble, ceramic tiles, granite, gemstones, crystal stones, rubber, bamboo and wood, musical instruments, electrical parts, leather and a variety of craft products.

The curing method of cyanoacrylate is hygroscopic curing, which needs to have a chemical reaction with water molecules in the air during curing, and heating more than 40 degrees will detach the moisture on the surface of the material, thereby slowing down the curing speed of cyanoacrylate, therefore, increasing the space humidity can improve the curing speed of cyanoacrylate.

Cyanoacrylates do not have to be applied over a large area, after all, the more glue is applied, the more moisture is needed for solidification, so it is recommended to use it in a small area.

The gluing begins to solidify when it comes into contact with moisture, so within 30 seconds after the gluing, the source chain should be destroyed to accurately fit the material and make the two contact surfaces fit tightly.

The common cyanoacrylate products on the market include Loctite 401, Loctite 403 and other cracked ants.

Cyanoacrylate is a one-component fast-curing adhesive synthesized through advanced production technology, mainly ethyl cyanoacrylate, adding tackifiers, thickeners, stabilizers, toughening agents, polymerization inhibitors, etc.; It is a high-strength, fast-moving adhesive, which can be used for high-speed bonding of various types of materials, especially suitable for use in the wood industry; For tight adhesion, porous materials such as rubber, metal, plastic, wood, etc. can achieve the strongest bonding effect; This glue is a single ingredient, solvent-free, no need to add catalysts, heating or pressure adhesives, only a thin layer of glue, it can use the atmospheric humidity in the air to produce a high degree of polymerization, to achieve the best bonding effect. There are natural adhesives and synthetic adhesives, and can also be divided into organic adhesives and inorganic adhesives.

It is mainly composed of binder + curing agent + filler + plasticizer + toughening agent + diluent.

Cyanoacrylate adhesives are one-component, low-viscosity, clear, ambient fast-curing adhesives. The bonding surface has good adhesion ability to most materials, and is one of the important room temperature curing adhesive grades. The shortcomings are that the reaction speed is too fast, the water resistance is poor, the brittleness is large, the temperature resistance is low (<70), the shelf life is short, and the durability is not good.

The main material is a specific cyanoacrylate, plus some auxiliary substances such as stabilizers, thickeners, plasticizers, polymerization inhibitors, etc. Water vapor should be isolated as much as possible when dispensing glue, and packaging containers should also be less breathable or non-breathable. The most common binder for reactive acrylate (structural) adhesives is methyl methacrylate.

This glue is characterized by fast curing, high bonding strength, bonding surface, the surface of the adhesive does not need to be strictly treated, and the dosage of each component of the two-component glue does not need to be strictly required. The downside is that the smell is not good. The glue formed by the simple (methacrylate) monomer is brittle after curing and has poor impact resistance, so some other compounds are often added to improve the toughness of the adhesive layer and improve the mechanical properties and environmental resistance of the adhesive layer.

If the added compound does not participate in the reaction when the glue cures, but only exists in it as a toughening agent, this type of glue is called a first-generation acrylic structural adhesive (FGA). If the added compound can be grafted and copolymerized with the monomer when the glue is cured, and the modification is carried out from the molecule, this kind of adhesive is called the second generation of acrylic adhesive (SGA). There is also a class of photosensitizers and sensitizers instead of peroxide initiators and accelerators in the dispensing of glues, which constitute the third generation of acrylic adhesives (TGA) cured by ultraviolet light or electron beam, which cures faster, stores more stably, and is one-component.

Cyanoacrylate is generally dispensed with an instant glue dispenser.

The working principle of cyanoacrylate dispensing is to use dispensing equipment to dot other glues such as instant adhesive or instant glue at the position where it needs to be laminated, to fix the components to be bonded, and then after curing, it is pressed and treated. Cyanoacrylate dispensing is carried out automatically according to a set program.

Cyanoacrylate dispensing.

The equipment used in cyanoacrylate dispensing processing is different from the ordinary pneumatic dispensing machine, the instant adhesive dispensing processing does not need air pressure, just turn on the power supply, and the fast adhesive dispensing processing effect required by the customer can be regularly and quantitatively dripped out, there is no blockage, dry glue, leakage and other problems, good precision, easy operation.

1) Epoxy adhesive binder mainly uses epoxy resin, and the most widely used in China is bisphenol A type, commonly known as "universal glue".

2) The modified phenolic adhesive has good heat resistance, aging resistance, and high bonding strength, but it has high brittleness and curing shrinkage.
