MG Chemicals 842WB - EMI Conductive Paint
EMI Conductive Paint 842WB is a 1-part, water-based conductive paint, pigmented with highly conductive silver flake. It is easy to use, with no let-down and no heat cure necessary. It can be applied by spray, brush or roller. It adheres strongly to most injection-molded plastics, such as ABS, PBT and PVA. It also bonds well to drywall and can be painted over with common architectural paints. 842WB is designed to reduce EMI/RFI interferences in architectural and electronic applications.
