What are the main components of Instant Adhesive Base?
Instant Adhesive Base, that is, instant-drying adhesive matrix. Its main components often contain cyanoacrylate compounds. Cyanoacrylate, a chemical wonder, contains cyanoacrylate (-CN) and acrylate group (-COOR) in its molecular structure.
The combination of these two makes instant-drying adhesive unique. Cyanide has strong electron absorption and polarizes molecules. It can react rapidly with substances containing active hydrogen such as hydroxyl (OH) and amino (-NH). Acrylate groups give adhesives good film-forming properties and cohesive strength.
When the Instant Adhesive Base comes into contact with moisture in the air or a trace amount of moisture on the surface of the adhesive, cyanoacrylate is rapidly hydrolyzed and polymerized. The process of hydrolysis is like a chain reaction, where the monomer molecules are connected one by one to form a long chain polymer, thereby achieving rapid curing, so that the adhesive is firmly adhered.
In addition, to adjust its performance, plasticizers are added to increase flexibility, stabilizers are added to ensure storage stability, or fillers are added to improve its mechanical properties. All kinds of ingredients, complementing each other, build the wonderful function of Instant Adhesive Base, in many industries, such as electronics, medical, manual, etc., all have extraordinary performance, can quickly stick objects, form a firm combination, is actually a wonderful choice of glue.
Instant Adhesive Base Materials
Instant Adhesive Base, that is, the instant adhesive matrix. There are many suitable materials, among which there are mysteries, let me explain them one by one.
Metals such as steel, copper, aluminum, etc., are all suitable materials. Because instant adhesives can form a strong chemical bond or mechanical bite with the metal surface. Steel has a solid texture, and although the surface has a certain roughness, the instant adhesive can penetrate into its microscopic pores. After curing, it is closely connected like mortise and tenon, so that the metal parts are firmly bonded. The surface chemical activity of copper and aluminum is suitable, and the adhesive can quickly react with it to form a stable bonding force. It is commonly used in metal equipment assembly, metal handicraft production and other scenes.
Plastic materials are also suitable. For example, ABS plastics, with moderate surface polarity, instant adhesives can effectively wet and adhere, and are widely used in the assembly of electronic product shells. Another example is polyvinyl chloride (PVC), instant adhesives can fill its surface micro-defects and achieve good bonding, and are often used for plastic product repair and splicing. However, it should be noted that some low surface energy plastics, such as polyethylene, polypropylene, etc., require special treatment due to their smooth surface and strong chemical inertness.
Ceramics are also suitable for Instant Adhesive Base. Ceramics are hard and brittle, and instant adhesives can form a high-strength connection on the ceramic surface. They can be used to repair damaged ceramic utensils or to create ceramic artworks. Its rapid curing feature prevents the displacement of ceramic parts during the bonding process, ensuring accurate docking.
In addition, rubber materials, whether natural rubber or synthetic rubber, can be well combined with instant adhesives. In the production and repair of rubber products, instant adhesives can provide immediate and long-lasting bonding effects, so that rubber parts are closely connected to meet the needs of different application scenarios.
Wood materials can also use instant adhesives. The wood surface is porous, and the adhesive can penetrate it, forming a stable bond after curing. In woodworking, furniture repair, etc., instant adhesives can quickly fix wood parts and improve work efficiency.
Glass is also suitable for Instant Adhesive Base. The glass surface is smooth and chemically stable, and the instant adhesive can form a transparent and firm connection on its surface. It is commonly used in glass handicraft production, glass doors and windows sealing and other fields.
In summary, Instant Adhesive Base is suitable for materials covering metals, plastics, ceramics, rubber, wood, glass, etc. However, when used, it needs to be pre-treated or selected according to different material characteristics to achieve the best bonding effect.
How long is the curing time of Instant Adhesive Base?
Instant Adhesive Base is also the base material for quick-drying bonding. Its curing time is long, which depends on many factors and is difficult to determine.
Guanfu quick-drying adhesives and the like, the curing period often varies depending on the temperature and humidity of the environment, the material of the bonding object, and the thickness of the glue. If the temperature is high and dry, the curing process is also fast; if the temperature is low and the humidity is heavy, the curing time is delayed.
As for the bonding materials, the materials are different, and it also affects the curing time. For example, bonding metals and bonding wood, due to the different properties of the two to absorb glue, the curing time is different. The surface of metal is mostly smooth and dense, the glue is difficult to penetrate, and it may take a little longer to cure; the quality of wood is porous, and the glue is easy to enter, or it can be cured slightly faster.
The amount of glue applied is also the main reason. If the glue is thick, the internal curing time is long; if the glue is thin, the surface and the inside are easy to solidify.
With common sense, at normal room temperature (about 20 to 25 degrees Celsius) and moderate humidity (about 40 to 60%), the thin coating Instant Adhesive Base is made of common materials, and the curing may take a few seconds to a few minutes. However, this is only a rough estimate. In actual operation, it must be determined according to the specific situation and cannot be generalized.
What are the Instant Adhesive Base Storage Conditions?
Instant adhesive base material, the method of hiding, is related to its nature and quality, so it needs to be treated with caution. Instant adhesives have the characteristics of quick drying and strong adhesion, and their base materials also have corresponding storage regulations.
First of all, avoid water and fire. Fire can cause it to explode, causing catastrophe; water, or react with the base material, damage its viscosity and quality, so it should be placed in a dry and non-flammable place. And it is advisable to choose a well-ventilated place. Well ventilated, it can disperse its volatile components, prevent accumulation and risk, and also ensure its stability.
times, temperature control is essential. If the temperature is high, it may cause the base material to react quickly and cause deterioration; if the temperature is low, it may coagulate and lose its activity. Usually, it should be stored between five and twenty-five degrees Celsius.
In addition, it is also heavy to avoid light. Ultraviolet rays in light can promote the transformation of the base material and damage its performance, so it is held in a dark container and hidden in the dark.
Repeat, to prevent impurities from entering. Dust and foreign matter enter, messing with its structure, reducing viscosity and stability. The reservoir must be strictly sealed and closed after use to prevent impurities from entering.
And, separate categories. Different binders are different in nature, mixed or have adverse reactions, so they are separated according to their categories.
In accordance with these articles, the quality of the adhesive binder can be guaranteed immediately, its service life can be prolonged, and it is safe and secure.
How to use Instant Adhesive Base
Instant Adhesive Base is the instant-drying glue base, and its usage is as follows:
If you want to use Instant Adhesive Base, first clean the surface. Wipe off dust and oil with cloth to make the surface clean and free of dirt, so that the glue force can be firmer. If there is rust or paint on the surface, you need to grind it lightly with sand to make it rough and able to hold glue.
Take an appropriate amount of glue for the second time. Depending on the size of the object and the width of the joint, control its dosage. If there is too much glue, it will overflow and become dirt, and after drying, it will form a block, which will damage its appearance; if there is too little glue, the force will not be solid and it will be difficult to stick to each other.
Then paste it. Apply the glue to one of the surfaces quickly, then fit the two objects together, and apply a little pressure to make the two close together. Because of its fast drying speed, the action should be sensitive to avoid missing the opportunity. When applying pressure, it should be stable and even, so that the glue is distributed all over the interface, and the paste is firm.
After pasting, let it stand in a stable place, and wait for it to dry. When it is not dry, do not move or shake to prevent displacement and debonding. The drying time varies depending on the characteristics of the glue, the material of the object, and the temperature and humidity of the environment, ranging from a few seconds to a few minutes.
When using Instant Adhesive Base, be cautious. If the glue touches the eyes and skin, rinse it with water quickly, and seek medical attention for those who are serious. And after use, close the container and put it in a cool and dry place to avoid fire and heat to prevent deterioration and failure.
