Good Reliability Conductive Silver Paste with 70% Ag Content
for Automotive Windshield
LEED-INK Silver paste DT5575 series is 70% Ag content silver
conductive paste specially designed for automobile windshield
defogging. It forms the pattern on the automobile glass through the
silk screen printing process. It is with excellent adhesion and
good oxidation resistance.
The firing range is adapted to suit toughened glass requirements.
After drying and heating process, the metal silver conductive wire
is formed on the automobile glass. When the power is electrified,
the heat can be generated and the frost on the glass can be
The silver paste has the advantages of strong welding adhesion,
good welding resistance and aging resistance, perfectly matching
with black glaze, etc.
|Ag Content (%)||70|
|Leveling Time||At room temperature, 2-3min|
|Drift of Resistance after Reliability Test (%)||＜10|
|Shelf Life||Six Months from Date of Shipment|
1. Good Acid Resistance
Put the sample soaked in 0.1N sulfuric acid solution(at room
temperature) for at least 2 hours, remove the silver layer with
adhesive tape and no Ag transfer, and the resistance drift is less
than or equal to 8%.
2. Excellent anti-oxidation and anti-sulfide properties
Put the sample soaked in 400g ethanol plus 1g sulfur
powder(elemental sulfur) solution for over 2 hours, the surface
shall no significant change(yellow or black).
3. Strong adhesion, good welding strength
DT557X-H series is with excellent adhesion. The silver paste
exhibit a minimum degree of silver migration stain into the glass,
after being fired. There ‘s no loss of adhesion or continuity
between the conductors and the backlite.
4. Small change of resistance with long-time printing
The resistance drift could be controlled within 10% during lab
testing. It shows the paste could keep stable performance after
printing and firing process.
