80% Ag Content Conductive Silver Paste for Car Front Windshield

with Strong Adhesion


Description

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).


Applications

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.

Feature Advantage


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).
