PSP-NP050-IS

PSP-NP050-IS
 

Product Description
 
PSP-NP050-IS is a nanosilver based screen printable paste that is used for thin film PV, sensors and general printed electronics applications. The paste is compatible with glass and transparent conductive coated glass substrates.
 
Product Benefits
 
•  High coverage
 
•  Low temperature sintering temperature
 
•  Excellent adhesion
 
•  Excellent electrical conductivity
 
•  Deposition using syringe or screen printed
 
Paste Preparation
 
PSP-NP050-IS is a single part nanosilver based paste system. The paste should be gently stirred before use avoiding incorporation of air bubbles. Any paste removed from its container should be used within 6 hours to ensure consistent deposition. After 6 hours quality cannot be guaranteed. Once the paste has been removed from the container for printing, this may introduce contamination. Please do not replace the paste in the container.
