This conductive silver pen is simple and efficient to use for adhering samples to SEM stubs. Designed to produce 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. If you wish to use the pen for traces, solderable terminations are possible using a 120ºC cure for 15-20 minutes. Tin, lead or silver solder can be used (do not exceed 180ºC for more than 5 seconds). Each pen is able to make approximately 30 metres of traces. 39-45% silver content; particle size is under 10µm diameter. Thinner is butyl acetate.
