Photosensitive Conductive Material RAYBRID™ Paste for Metal Mesh
RAYBRID™ paste for metal mesh (SFAG Series) is a conductive paste with photosensitive characteristics. Toray's proprietary polymer design technology allows the formation of high-definition wiring, provides an alternative to ITO, and is used mainly for touch panel metal mesh applications, etc.
- High-definition wiring formation is possible with photolitho processing after coating with a slit coater.
- High-definition formation is possible with Toray's proprietary polymer design technology.
- As it has lower resistance than ITO, it is suitable for large touch panels in automobiles, etc.
- Because it is a material with good flexibility, is it suitable for flexible sensors.
After applying RAYBRID™ evenly to the glass or polyimide board with a slit coater, etc., form the desired pattern with photolitho. Then cure the pattern by applying a baking step of 230°C before use.
