PELCO® Isopropanol Base Conductive Graphite Adhesive

PELCO® Isopropanol Based Graphite Paint

Conductive graphite paint, primarily designed for SEM sample preparation. The graphite flakes, with an average size of 1µm, are bonded by a cellulose resin with isopropanol as diluent. Good bonding properties on most materials. Graphite content is 20%. Ideal to mount samples on sample stubs or to make a conductive path to the sample surface. Let fully dry before using in the SEM. Maximum service temperature: 200° C. Use Graphite Paint Extender to dilute when needed.

PELCO Tabs™ Carbon Conductive Tabs, Double Coated

The simplicity of application and smooth, clean surfaces of PELCO Tabs™ Carbon Conductive Tabs are a significant improvement compared to many of the other common adhesives that have been used in SEM mounting. Both tab sides have a thick conductive adhesive (conductive inner tab is 35µm and the adhesive is 45µm on each side for a total thickness of 125µm [5 mils]) with a liner on both sides, a transparent liner and white liner respectively. They are ready for immediate use. The top protective liner does not have to be removed until the sample is ready to be mounted. This reduces possible contamination. Outgassing is negligible.

Application of the tab to a mount or surface should be done slowly and carefully to maintain surface smoothness.

The conductive adhesive is a carbon filled acrylic, free of solvents. It can be removed from the specimen mount with ethyl acetate, ethanol, isopropanol, alcohols or our 3M™ Adhesive Remover 80924 which is solvent-free. Temperature maximum is 60°C (140°F). High purity carbon tabs may contain very small impurities of Al and Si; see EDX Spectra.

This product may also be used for gunshot residue analysis.
Many laboratories use these tabs for SEM in a large diversity of applications. Refrigeration will increase shelf life but a warm up period of one hour is then required before use.

The PELCO Tabs™ consist of a carbon fiber mat impregnated with carbon filled acrylic adhesive. There is no internal carrier film.

carbon conductive tape

Carbon Conductive Tapes, Double Coated

These carbon tapes are conductive and may be used conveniently for scanning electron microscopy or EDS applications.

This is the same material as the PELCO Tabs™, Carbon Conductive Tabs, but in tape form. The tape form allows for special application uses such as custom sizes, cut-outs and shapes. The purity of this tape is identical to the PELCO Tabs™; only very small impurities of Al and Si may be found.

Both sides of the tape have a thick conductive adhesive (conductive inner film is 35µm and the adhesive is 45µm on each side for a total of 125µm [5 mils]) with a white liner. The double adhesive and conductive design permits quick mounting of samples without using liquid or colloidal adhesives.

The tape is relatively solid and non-porous and does not absorb small samples. The variety of widths affords efficient application to various specimen mount surface sizes. Thickness is 0.16mm. Available in six widths. Can be used down to -20°C (-4°F) and temperature maximum is 60°C (140°F). Available in 5, 8, 12, 20, 25, and 50mm W x 20m L (0.19, 0.31, 0.47, 0.79, 0.98, and 1.96" x 21.8 yd). Core diameter is 76mm (3"). SEM mounts not included.

copper conductive tape

3M™ Copper Conductive Tapes, Single Adhesive Surface

The tape is easily cut to size and may be quickly applied to a specimen mount or other surface. Carbon or metallic coating normally is applied to the sample and mount. An electrical discharge bridge is then completed from sample, through the copper and its conductive glue to the grounded specimen mount.
The tape is dead soft copper with a conductive acrylic adhesive. It is supplied on a removable liner for easy handling and cutting. The tape offers excellent conductivity through the foil backing.
This tape is 6.3mm W x 16.46m L (1/4" x 18 yd) or 12.7mm W x 16.46m L (1/2" x 18 yd) and the core diameter is 76mm (3").

Foil Thickness: 0.04mm (0.0014")
Total Thickness: 0.07mm (0.0028")
Resistance through Adhesive: 0.005 ohm
