842WBU – EMF Blocking Paint for Electronics

High-Performance Conductive Coating for Electronics & Building Shielding

842WBU is a one-part, water-based conductive shielding paint formulated with highly conductive silver flakes to provide outstanding EMI/RFI and EMF shielding. It is ready to use with no mixing, thinning, or heat curing required, and can be applied easily by spray, brush, or roller.

Designed for both electronic and architectural applications, 842WBU delivers reliable shielding performance from low frequencies up to 40 GHz, making it suitable for today’s high-frequency wireless technologies, including 5G, Wi-Fi, Bluetooth, RFID, and other RF signals.

Superior EMF & EMI Shielding

842WBU effectively reduces electromagnetic interference (EMI), radio frequency interference (RFI), and electromagnetic field (EMF) exposure generated by wireless communication systems and electronic equipment.

The conductive silver flake network provides excellent attenuation across a broad frequency range, helping shield against:

• 5G networks
• Wi-Fi
• Bluetooth
• Cellular signals
• GPS
• RFID
• Radio frequency transmissions

Advanced Silver Flake Technology

842WBU uses premium silver flakes that provide:

• Excellent electrical conductivity
• Superior shielding effectiveness
• Better surface coverage with thinner coatings
• Reduced material consumption
• Lower application costs

The flat silver flake structure creates an efficient conductive pathway for maximum shielding performance.

Easy Application

The coating is supplied ready for use and bonds well to a variety of substrates, including:

• Drywall
• Wood
• Concrete
• Plastic
• Steel
• Aluminum

Once cured, the surface can be painted over with standard latex or decorative paint without affecting appearance.
