1, reduce the conductive properties: conductive paste after the expiration date, the conductive properties may decline. The main role of the conductive paste is to improve the signal transmission effect, so that medical equipment can better detect and treat the disease. If the conductive paste expires, it will result in poor signal transmission and affect the accuracy and effectiveness of the device.
2, increased safety risks: expired conductive paste can cause adverse reactions or trigger allergic reactions. Some people may be allergic to the ingredients in the conductive paste, the use of expired conductive paste will cause skin irritation, redness, swelling, itching or other uncomfortable symptoms. Conductive paste after the expiration date can also be deteriorated or damaged, odor, color change, dryness or caking and other problems, increasing the safety risk when using conductive paste.
