Water Based Conductive Paint
MG Chemicals WB series are water-based
conductive paints that are designed for protection
against EMI/RFI. These easy-to-use, 1-part systems
are intended for use in building interiors where
shielding against EMI/RFI is a necessity. Compared
to the AR series, WB paints enjoy the benefits of
being non-flammable, low VOC and having low odor.
Features and Benefits
• 1-part system
• Ready to spray, no dilution required
• Low odor
• Excellent adhesion to drywall and most plastics
• Ships as non-DG by air
• Can be painted over with architectural paints
Applications
• Plastic enclosures for PCBs
• EMI shielding for operating rooms and military
facilities
841WB - Nickel conductive paint for broad
spectrum shielding
842WB - Silver conductive paint for premium
shielding performance
843WB - Silver-coated copper conductive paint
which balances cost and EMI performance
