842UR is a one-part, heat-cured, silver polyurethane coating. It is a smooth, flexible, abrasion resistant coating that provides excellent electrical conductivity and high frequency shielding at a low film thickness. It maintains flexibility at low temperatures, provides exceptional adhesion to a wide variety of substrates, and provides excellent environmental stability.

842UR is designed for large volume board-level or package-level EMI/RFI shielding applications. It can replace traditional metal cap, which reduces cost, board thickness, and mass.
