High conductivity 60% Ag Content Conductive Silver Paste for
with Good Acid Resistance
Silver paste DT5575-H is environmental conductive paste with 60% Ag
content and specially designed for automobile backlites for
defogging and defrost uses.
It is with excellent adhesion and good oxidation resistance, and
has good compatibility with common black glaze on the market. It is
non-toxic up to European RoHS environmental regulation
DT5575-H series silver paste is mainly applied on automobile window
glass and electrically heated backlites 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.

|Acid Resistance||Qualified. Conditon: The samples were soaked in 0.1N sulfuric acid
solution after 2 hours (at room temperature), with tape attached to
exposing the silver layer no Ag transfer, resistance drift is less
than or equal to 8%.|
|Anti Vulcanization||Qualified. Condition: The sample was soaked in 400g ethanol +1g
sulfur powder (elemental sulfur) solution for 2 hours (at room

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. 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.
3.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.
4. Wide firing temperature range
The firing temperature range is wide as 680-710℃ and it could meet
most production process requirement.
5. Good compatibility with black glaze
The product has good compatibility with common black glaze products
on the market. After the silver paste firing, the silver line is
invisible through the black glaze from the printing reverse side,
which shows good compatibility with the black glaze.
