MG Chemicals 841WB - EMF Shielding Paint
EMF Shielding Paint 841WB is a 1-part, water-based conductive paint, pigmented with highly conductive nickel 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. 841WB is designed to reduce EMI/RFI interferences in architectural, electric musical and electronics applications.

- Recommended Preparation
Plastic—Clean the substrate with Isopropyl Alcohol, MG #824, so the surface is free of oils, dust, and other residues. Drywall—For new drywall, apply directly on top of the drywall primer, after the primer has properly cured. When applying on top of existing paint, first wash the wall with a solution of T.S.P. diluted with water at a 1:10 ratio, to ensure good adhesion.
