Electromagnetic Shielding Paint
843WB is a 1-part, water-based conductive
paint, pigmented with highly conductive silver-
coated copper flake. It is easy to use, with no
let-downandnoheatcurenecessary.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.
843WB is designed to reduce EMI/RFI
interferences in architectural and electronic
applications.

Application Instructions
Read the product SDS and Application Guide for
more detailed instructions before using this product
(downloadableatwww.mgchemicals.com).
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.
Paint Roller
This product may be applied with a standard paint
roller.Thinningisnotrequired.
Manual Spray Guns
Useastandardfluidnozzleguntospraythepaint.The
settings listed below are recommendations; however,
performancewillvarywithdifferentbrands:
