1. Product Overview

842AR Super Shield™ Silver Conductive Paint is a one-part, solvent-based acrylic lacquer filled with highly conductive silver flakes. It provides excellent EMI/RFI shielding, strong corrosion resistance, and durability, while being smooth, hard, and abrasion-resistant. The coating adheres well to plastics such as ABS, PBT, and PVA. It requires no heat cure, dries quickly, and is suitable for marine and high-frequency shielding applications. Available in jar, can, and aerosol formats, it offers flexibility for various application methods.


2. Applications

  • Conductive coatings for plastic electronic enclosures.

  • Suppression of EMI/RFI emissions at high frequencies.

  • Board-level shielding where minimal film thickness is required.

  • Corrosion-resistant coatings for harsh or marine environments.

  • Suitable for brush, spray, or selective coating applications.
