Low-temperature conductive silver paste carrier resin LR-9100 for film switch touch screen keyboard

The significance of carrier resin in low-temperature conductive silver paste for membrane switch touch screen keypads

Low-temperature halogen-free conductive silver paste is a light asset manufacturing industry, primarily dependent on carrier resin, silver powder, and formula elements.

Low-temperature halogen-free silver paste is a conductive functional material used in the preparation of flexible electronic circuits such as membrane switches, touchscreens, and keyboards, with the quality of the carrier resin being a key factor in determining the paste's excellent film-forming properties.

The carrier resin in conductive silver paste must first meet the requirements for rheology, conductivity, adhesion, flexibility, printability, resistance to sweat, oxidation resistance, and hardness, etc., in the manufacturing of electronic circuits.

Secondly, the leveling, volatility, and rheological behavior of the silver paste carrier resin are crucial for ensuring that the paste transfers from the silk screen mesh to the workpiece surface during the printing process, forming conductive patterns on the film switch touch screen keyboard.

Classic saying in the slurry industry: Only with superior carrier resins can high-performance conductive silver paste be produced.
