Good Solderability 80% Silver Contain Conductive Silver Paste for Automotive Windshield


DT5572(80% silver contain) is a well-developed conductive silver paste with high performance in printing hot wire for automotive backlights. This productdoes not contain toxic elements such as lead, in line with the EU ROHS Directive (2002/95/E).
Advantages of our conductive paste product: good printability & solderability, high adhesion & resistance stability.


The silver paste is mainly applied on automobileelectrically heated glassfor 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 firing range is adapted to suit toughened glass requirements.

Featured Advantage

1.Wide firing temperature range
The firing temperature range is wide as 600-650 and it could meet most production process requirement.

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).
