Application
Introducing our premium gold nanoink, specifically designed for inkjet printing across a diverse range of substrates. This high-performance ink features gold nanoparticles with an average size of around 4 nm, ensuring exceptional conductivity and adhesion. With a gold concentration of 40% and a viscosity range of approximately 7-10 cP, this unique formulation allows for excellent solubility in nonpolar organic solvents while maintaining stability under atmospheric conditions at room temperature. Ideal for use on materials such as polymers, ITO, and glass, our gold nanoink is particularly suitable for applications requiring fine line printing due to its low sintering temperature and impressive resistivity results. Designed for both industrial and innovative creative projects, this cutting-edge nanoink technology is tailored to enhance your applications with precision and reliability.

Other Notes
FAQs: Q1: What adjustments can improve sintering results, especially with older ink?
Answer: Try increasing the sintering duration or slightly raising the temperature. These adjustments can enhance results when using older ink.
Q2: How does storage duration affect the ink’s condition?
Answer: If the ink has been stored for around seven months, its condition can vary depending on how it was stored.
Q3: Is ink still usable after being refrigerated for several months?
Answer: Yes, refrigerated ink is generally still usable. However, it may require longer or higher-temperature sintering to achieve optimal performance.
Q4: What can be done if the ink contains bulk material?
Answer: You can centrifuge the ink at a low speed (around 500 rpm) to help remove any bulk material.
Q5: What degradation risks are there if the ink was not sealed or sparged?
Answer: Without proper sealing or sparging (using Argon or Nitrogen), the ink may degrade over time. This could result in reduced concentration. Centrifuging can help, but performance may still be affected.
Q6: What is the recommended storage method for ink kept longer?
Answer: Sparge the ink with Argon or Nitrogen and seal it with electrical tape to preserve quality during extended storage. For best results, sparging the bottle with argon to displace oxygen and moisture is recommended, along with ensuring a secure seal. Periodically inverting the bottle to remix the contents helps maintain uniformity and prevents settling.
