EM-Tec conductive paints, pastes and cements
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 C30 premium water based conductivecarbon paint
- EM-Tec C32 novel water based graphene-carbon paint
- EM-Tec C33 fast drying conductive carbon paint
- EM-Tec STC33 Isopropanol solvent / thinner / cleaner for EM-Tec C33 carbon paint
- EM-Tec C38 strong conductive carbon cement
- EM-Tec AG15 silver paint
- EM-Tec STC15 MEK solvent / thinner / cleaner for EM-Tec AG15 silver paint
- EM-Tec AG42 strong and highly conductive silver cement
- EM-Tec AG44 conductive silver paint
- EM-Tec AG46 water-based conductive silver paint
- EM-Tec NI41 strong and good conductive nickel cement
- EM-Tec STC39 Acetone solvent / thinner / cleaner for Acrylic based conductive paints / 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. The EM-Tec C30 premium water based conductive carbon paint is solvent free and should be preferred to avoid hydro-carbon contamination in the SEM.
