Performance Description

Instructions and guidance for use

Substrate: PTC ceramic, pressure-sensitive ceramic

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: This product is suitable for printing various PTC and pressure-sensitive ceramics. The thickness and resistance of the cured film are affected by many related factors, such as the size, tension, scratch hardness, angle and speed of the screen board, and the thickness of the photosensitive adhesive.
