80% Ag Content Conductive Silver Paste for Car Front Windshield
with Strong Adhesion
Silver paste DT5572 is environmental conductive silver paste with
high silver content and specially designed for car front windshield
glass for defogging and defrost uses.
It is with 80% Ag content and with good adhesion, excellent welding
strength, good oxidation resistance, and it is non-toxic up to
European RoHS environmental regulation (2002/95/EC).
DT5572 silver paste is mainly applied on car front windshield (also
suitable for backlite depends on the firing process) for defroster
and/or defogger purposes.
It forms the pattern on the automobile glass through the silk
screen printing process. 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 removed.
The silver paste has the advantages of strong welding adhesion,
good welding resistance and aging resistance, perfectly matching
with black glaze, etc.

1. Strong adhesion, good welding strength
DT5570 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.
2. 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.
3. 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%.
4. 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).
