This pen is great for adhering samples to SEM stubs!
Designed for making instant conductive silver traces, the specially formulated silver-bearing thermoplastic polymer dries in minutes at room temperature. Valved pen tip allows smooth flow with normal writing pressure and is spring-loaded to prevent clogging.
The trace width is pressure-sensitive: for thin traces, hold the pen lightly; for thicker traces, apply more pressure while holding the pen.
If you wish to use the pen for traces, solderable terminations are possible using a 250 degree Fahrenheit cure for 15-20 minutes. Tin, lead, or silver solder can be used (do not exceed 350 degrees Fahrenheit for more than 5 seconds).
Each pen is filled with approximately 100 feet worth of traces. Approximately 39-45% silver with less than 10 micron diameter. Thinner is Butyl Acetate.
I used the silver pen on my new z-scale layout to avoid soldering each rail joint and it worked great. I have no drop in voltage at all. I also used the silver pen and the carbon paint on rail joints of my backyard garden railway in some locations with great results also.
That is awesome!! The Carbon Paint and the Silver Pen are very popular with railroad enthusiasts. Thank you for taking the time to leave a review, it will help others who might be searching for a product for a similar application. Enjoy your trains!
