Conductive paints, pastes and cements
Conductive paints and adhesives are indispensable for SEM and FIB specimen preparation and specimen mounting. They enable quick specimen mounting and deliver the conductivity needed for SEM and FIB applications.
EM-Tec conductive paints and cements from Micro to Nano are specially selected for specimen preparation use in electron microscopy, focused ion beam, electron microprobe and scanning probe applications. EM-Tec conductive paints, pastes and cements offer different properties to cover a variety of applications.
Conductive paint and adhesives are ideal to make conductive paths to ground for SEM specimens. Used for making contacts, conductive bonding of specimens on specimen stubs or shielding surfaces of non-conducting specimens. EM-Tec conductive paint and cements are used for many applications besides electron microscopy in repairing contacts, tracks on circuit boards, prototyping, conductive lubrication, electrochemical plating and EMI/RFI shielding. EM-Tec C30 premium water based conductive carbon paint is solvent free and should be preferred to avoid hydro-carbon contamination in the SEM.
EM-Tec conductive silver epoxies enable embedding and cementing specimens and parts providing high conductivity and good mechanical strength. When the epoxy is cured, the specimen can undergo further preparation steps such as polishing, lapping, thinning, etc. Epoxies are not suitable for soldering, but create conductive contact. EM-Tec silver filled epoxies are a two component system supplied in two syringes. To improve conductivity and to make mixing easy, both components are silver loaded. The amounts of the EM-Tec silver epoxy sets are chosen for affordability, yet sufficient for experiments, specimen preparation and prototyping.
