Excellent Acid Conductive Silver Paste For Automotive Windshield
Silver pastes are screen-printed on glass or black varnish then
fired a second time in glass kiln. It is with features of standard
conductivity silver pastes, low-emission silver pastes (with black
pigment), high conductivity silver pastes for printing thin lines
Every series of these silver-based inks is created by mixing two
components, respectively with high and low silver content, which
make it possible to obtain specific silver contents and resistivity
values according to the resistance required for the circuit.
The last generation of unleaded silver pastes show stunning baking
and adhesion characteristics, in addition to high performances in
mechanical and chemical resistance.
DT557X series silver paste is mainly applied on automotive
electrically heated glass 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.

|Shelf Life||Six Months from Date of Shipment|
1. Strong adhesion, good welding strength
DT557X series is with excellent adhesion. The silver paste exhibit
a minimum degree of silver migration stain into the glass, after
2. Wide firing temperature range
The firing temperature range is wide as 600-650℃ and it could meet
most production process requirement.
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).
