Instructions and guidance for use

Usage: RFID internal electrode

Mixing: thoroughly mix before use.

Dilution: This product can be used after stirring evenly. It is recommended not to add diluent. If dilution is required, a specialized diluent should be used. It is recommended to dilute it by less than 3% of the weight of the silver paste, and then stir it evenly again after dilution. If the diluent added exceeds the above standards, the product quality and performance are not guaranteed.

Printing: The film thickness and resistance of ceramic substrates after curing are affected by various related factors, such as the size, tension, scraping hardness, angle and speed of the screen board, and the thickness of the photosensitive adhesive.
