Leit-C-Plast
carbon base, good conductivity, large specimens
Leit-C-Plast is a conductive adhesive paste that can be molded to provide conductive paths to larger non-conductive samples when mounted on a specimen holder for SEM studies.
The plasticity is permanent. It is not affected by high vacuum conditions and shows no peaks in energy dispersive X-ray microanalysis.
Heavy specimens may also be prepared for viewing in a SEM using Tempfix (or the Glue Gun – see details in our non-conductive section) and Leit-C-Plast.
First the specimen is fixed into place with Tempfix or the Glue Gun.
Afterward, an electrically conductive bridge is made between specimen mount and specimen using Leit-C-Plast.
It is not required to wait for drying because neither adhesive outgasses.
Leit-C-Plast was originally developed for holding specimens on angled specimen holders.
The adhesive is offered in a roll form and is black.
Flat plates are provided for working the material.
May be applied with a spatula.
