Kunshan Yosoar produces professional conductive copper paste, which has vast applications for the shielding of materials. The main material of conductive copper paste is composed of copper powder. Kunshan Yosoar has indeed got a wide variety of copper powders, including different shapes and varying particle sizes as well, that can generally be provided according to customer requirements Suitable product.
Used in screen printing
Because copper paste is composed of copper particles and other thermosetting resins, it can be used well in screen printing, mainly because it has high printability, low irritating odor, and high oxidation resistance.
When in use, it is easier to operate, and has good electrical conductivity, hardness, and adhesion.
Used in Soldering
Soldering is a welding method that uses a low melting point metal solder to heat and melt, and then penetrate and fill the gap between the metal parts.
Weldable conductive copper paste is dried with special diluent, but the dosage should not exceed 5%. The viscosity of the system is extremely sensitive to the diluent. Each time you add a very small amount of gradual test, you should use it up in time after opening the cover.
Yosoar: Detailed information on conductive copper paste
Under high-temperature conditions, this powder of copper can be easily oxidized into copper oxide, which is non-conductive, so when the sintering process of this powder takes place, the air must be isolated. Under normal circumstances, we use nitrogen for protection.
Conductive copper paste can also be cured at indeed low temperature, and the conductive paste of copper that is manufactured in our labs at Kunshan yosoar has good adhesion and good printability. Generally, it does not need to be electroplated but can be directly soldered. The fact is that it is indeed highly flexible whenever it is used.Conductive copper paste can also be diluted when a special thinner is added to it, but it should be taken into consideration that the amount not to exceed 5%.Kunshan yosoar’s copper paste should be stored at 0-5°C and can be stored for 3 months!
The copper paste produced by Kunshan Yosoar can be soldered and applied to PCB and seat shielding materials related application fields. Another application of this paste is that you can apply it on keyboards and the output electrode printing of solar panels.
Compared with traditional metal welding, the copper paste produced by Kunshan yosoar has the advantages of more convenience and simplicity.
Model of Paste
It is toxic under normal circumstances, but if it is directly ingested into the human body and just touched with your hands or body, it will be fine. Copper paste is a relatively safe colloid dispersed by nano-copper powder. If ingested, it will be poisonous because it will Reacts with things in the stomach, causing heavy metal poisoning.
First of all, if we consider the electrical conductivity as well as the thermal conductivity, conductive silver paste is better than conductive copper paste, especially after curing, the overall resistance offered by silver is tens or even hundreds of times lower when compared to that of copper, and after curing, the effect of silver paste on the stability is much more when compared to that of copper paste. Even when it is cured for a long time, it will have no effect on the conductivity. However, it will be easily oxidized for a long time, which will have a prominent effect on the conductivity. Therefore, conductive silver paste is more suitable than conductive copper ink. Used on the PCB board.
There are two functions of copper ink sintering. If we talk about the first one, then it is the removal the organic carrier in the drying film, which is removed under the phenomenon of the sintering furnace smoke. The other is that the glass in the paste of copper can be completely melted and bonded with the copper powder of the metal, thereby promoting the mutual penetration and bonding that is present among the copper powder, or between the copper powder and the body, and is the temperature The faster the decrease, the higher the overall viscosity of the glass will form a chain network structure between the film layers, and the copper film can be formed, which has the advantages of conductivity, solder resistance and adhesion.
Under normal circumstances, copper slurry sintering process is performed under the protection of nitrogen. The general sintering system includes heating rate, sintering temperature, cooling rate and so on.
If the solderable conductive copper ink dries, we maliciously use a special thinner, but it should be kept in consideration that the overall amount should not exceed 5%. Because the viscosity of the system is generally sensitive to the diluent, a small amount should be added for each test in order to carry out a step-by-step experiment, and it should be used up in time after opening the lid.
Conductive copper ink will oxidize and turn black during placement because copper paste has higher chances of getting oxidized than silver paste, and the conductive effect is not as good as silver paste. Copper is more likely to be oxidized. If the package is opened, it should be used up as soon as possible. If the time is longer, the efficacy will gradually decrease, and as a result, it will ultimately lead to the failure of the conductive copper ink.
If we consider this copper, then it is basically referred to as the high-temperature anti-seize lubricant.

Copper paste is basically an anti-seize compound that has vast number of applications. It has many benefits and can be used in various regards. As we know that copper ink has properties that allow it to prevent the corrosion and rusting of metal parts. All of this happens in such a way that the copper ink generally forms a layer between the metal surfaces. Basically this separating layer that forms between the metal surfaces prevent the rusting and corrosion of the metal parts and ultimately is very beneficial. Furthermore another aspect to this phenomenon is that it is very much effective even at the extremes of temperature. Therefore, this copper generally acts as a layer and prevents the metal to metal contact and acts as a lubricant, and provides lubrication to these connecting metal parts and as a result, the corrosion is reduced to much lower extent.
Is there any significant use of copper paste in ships?
This is definitely useful in ships and related works. As ships contain many mechanical parts and metal components that are required to be protected against corrosion and resistance. Therefore, you can definitely use this copper ink in this regard. This will ultimately benefit you in preventing the seizure if the moving mechanical as well as metal parts of the ship. This copper paste will also prevent the corrosion of these metal parts that happens die to humid conditions. Therefore, this is quite effective in this regard as it will help in preventing the rusting and corrosion of the parts of the ship. Similarly, because of high humid as well as saline conditions, the corrosion of the metal parts is also increased and this could be a severe issue in ships. This could be solved by the use of this paste of copper that will prevent this and ultimately will be most effective even at extreme conditions of temperature as well as pressure.
What is one of the most effective things to be present in such anti-seizing pastes?
One of the most important quality that an anti-seize compound should have and that will indeed make it the best is that such compounds should have a high quantity of active metal. The anti-seize compounds should have a paste that would be very thick. It means that it should have a relatively high density and viscosity as well. Apart from this, it should also have a high concentration or high quantity of active metals present in it. Furthermore, the overall amount of grease present in such pastes should also be very less. So these are some of the characteristics that when fulfilled will provide you with the best anti-seize paste ever.
The copper ink that we manufacture at Kunshan Yosoar is indeed one of the best copper ink. Our manufactured copper ink has very high thickness and the total amount or quantity of active metal ingredients is also very high. Apart from this, it also has very little grease in it.

This definitely has got some amazing anti-seize properties and these properties are fully functional at extreme temperatures as well.
How does copper paste prevent galvanic corrosion?
If we talk about galvanic corrosion, then it simply implies the process in which one metal corrodes and this metal basically corrodes because of the presence or because of the contact with another metal. So we can indeed say that such corrosion occurs when there are two metals and the corrosion occurs because if these metals. This is generally referred to as the galvanic corrosion.
Now referring to the use of copper ink in this regard, the copper ink is definitely effective and beneficial for preventing such galvanic corrosion. The copper ink basically forms a kind of layer between these two metal surfaces and prevents their contact with each other. When there will be no contact among the metal surfaces, then no corrosion will take place. Ultimately it will prevent the rusting and corrosion of such metal parts of machineries.
I wanted to know that whether the copper paste is toxic or not?
The copper ink is not that much toxic when working with it. But one thing should be kept in mind that while working with this paste, an individual should definitely keep into account the precautionary measures and should take some protection steps that would be beneficial. What I would suggest that with normal precautionary measures, this copper ink would not be that much toxic externally. But if an individual swallows it or inhales this copper ink, then the things could definitely get worse. When inhaled in the form of smoke or copper ink dust, this will cause some serious respiratory tract infections and issues. Apart from this, when ingested, this copper ink will become more poisonous as it contains some active metal particles. These metal particles will resukt in a reaction in the stomach and internal body and this could eventually lead to extreme metal poisoning.
Henceforth externally, this is not that much harmful but if you swallow it, then it will cause some extreme damage internally and will ultimately cause metal poisoning and in this regard it could be highly toxic
Is this copper paste effective for all types of joints and sliding surfaces that are made of metal?
This is indeed effective for all types of joints and sliding surfaces. This is mainly made for the protection of metal parts of heavy functioning machineries against the rusting and of the metal parts. This is also very effective in terms of lubricating such metal surfaces. This is most effective to be used on plugs, screws, threaded joints and bushings, etc. This copper ink prevents the wear and tear of the mechanical parts and also prevents the rusting and corrosion of these parts. It forms a kind of layer between the metal surfaces and prevents their direct contact. Ultimately preventing galvanic corrosion.
Therefore, this copper ink has indeed got many wide applications and is extremely beneficial in its use in the mechanical world.
