Strong Welding Adhesion Conductive Silver Paste for Automotive Front Windshield



LEED-INK Silver paste DT557X series is environmental conductive paste specially designed for automobile front windshield defogging. It is non-toxic up to European RoHS environmental regulation (2002/95/EC). It is with excellent adhesion and good oxidation resistance.

It is heavy-metal free and in compliance with the European legislation for end of life vehicles 2000/53/EC. All our standard compositions are provided with features of viscosity, which make them ready for use in order to get an optimal printing by using standard operating conditions on the part of the client.



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.

Featured Advantage


1. 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.

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).

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.
