Carbon Paint Cement
EM-Tec conductive paints, pastes and cements
Introduction
The EM-Tec conductive paints, pastes and cements are selected for sample preparation use in electron microscopy, focused ion beam, electron microprobe and scanning probe applications. The EM-Tec conductive paints, pasts and cements offer different properties to cover a variety of applications. The current product line consists of:
- EM-Tec C33 fast drying carbon paint
- EM-Tec C39 strong conductive carbon cement
- EM-Tec AG42 strong and highly conductive silver cement
- EM-Tec NI41 strong and good conductive nickel cement
Conductive paint and glues are ideal to make conductive paths to ground for SEM samples. Used for making contacts, conductive bonding of samples on specimen stubs or shielding surfaces of non-conducting samples. The 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.
