Yes, after prior background exchange with our commercial and technical department.

Our product has a duration of 12 months in the sealed container when delivered, once opened it depends on the type of application that is going to be developed, it is shelf-life.

We have a monthly capacity between 60 and 100 kilograms. We have an annual capacity of about 1.2 tons of nanoparticles in aqueous suspension.

The size is 23 nanometers on average. disk sheet morphology, see data sheet.

e are now authorized to claim that our Copper Nano-particles are Anti Corrosion agent, Anti Biofouling, Anti microbial and we are beginning to discover it’s antiviral properties. Research has shown that copper has anti-bacterial and anti-viral properties which make it a potential tool in the fight against the coronavirus (COVID-19). In this study, we found for the first time that nanosized Cu particles have antiviral activity. https://aem.asm.org/content/78/4/951 .

The copper nanoparticles are in aqueous suspension, i.e. in distilled water.

Cu Nps in aqueous suspension have a value depending on the requested volume. The price is established according to the type of application in which the copper nanoparticles are used, and considers the complexity of the type of copper nanoparticle that is prepared for each client.

The recommended dose will depend on the application you have, we have a technical team that can guide you in some aspects, but that is directly evaluated by the client and final product being developed.

We have a quality control laboratory, specially designed with measurement equipment, atomic absorption, DLS and others.

The duration is between 6 to 9 months

We engineer, produce and distribute Copper Nanoparticles in aqueous suspension and in powder as an additive for various applications. The second is that we develop and incorporate or blend our Copper Nano technology in your existing product to help you determine the required dosage.

Our nanoparticles are suspended in water in the presence of protective reagents that prevent their oxidation, the high concentrations of nanoparticles are not very friendly to dispersion, you could propose a methodology and we corroborate it, we usually send samples in suspension of between 1 at 5 grams per liter (0.01% to 0.05%), but we can reach concentrations greater than 10% or 15%, the stability at this concentration depends on how you proceed.

For Ink applications we can send the nanoparticles in water or Propylene Glycol, if you have another solvent in mind we could test the stability of the system and the concentration you want.

Copper nanoparticle is an additive for the formulation of Biocidal paints and products, ideally it is water-based for its rapid incorporation.

The literature precisely reports that the problem of dispersion has not been solved at present, since nano-particles below 10 nm are highly reactive in aqueous media. In general and given our laboratory experience, Cu Nps need to be protected in this environment using encapsulants and antioxidants to prevent the corrosive action of oxygen in the air. The presence of these additives does not contribute much to the dispersion and suspension of the system for long periods of time and they also do it selectively, that is, the Cu Nps with low surface free energy (large) decant more quickly than the small ones (high surface free energy) the latter being those that remain in suspension for a longer time (if they are with the additives). The property of a longer suspension stability time depends fundamentally on the chemical species that are part of the Cu Nps environment, which is directly linked to the chemistry of the system in which it is intended to be used, since in many cases it can generate an incompatibility between stabilizing additives and the chemistry of the final product produced. The reddish color can be confused with the agglomeration phenomena, especially in poly-disperse systems since the thermodynamic tendency of the system is the physical interaction between the particles finally generating groupings that produce this coloration. This is especially favored by the formulation of suspensions of high concentration in Nanoparticles.

As described on dispersion and stabilization Question previously., Our nanoparticles, even if they are agglomerated, the use of them in a heterogeneous system (paints) by injecting energy into their preparation easily allows them to be dispersed in this new system. This shows that it is finally the system in which the Cu Nps are to be used that gives the possibility of good or bad dispersion. Therefore, it is essential to understand that the use of them is specific to each system and therefore the interaction between the technical team of the buyer and seller is of fundamental importance for the success of their employment. Our nanoparticles are encapsulated and protected against corrosion with biodegradable additives and therefore friendly to the environment.

Now days fortunately, Nanotechnology is confronting regulators around the world with new technical, legal, and policy issues. Companies manufacturing, processing, or using nanomaterials for their revolutionary properties are progressively navigating a rapidly changing, and less diverse regulatory environment to be able to be registered as an applied product.

Our Cu Nps have three different populations arise from the observation of TEM which is only qualitative, but the size analysis by DLS and the AFM show a consistent value between them of 25 to 30 nm, which would indicate that the largest population of nanoparticles would be within these values.
