Parker Chomerics CHO-SHIELD® 4994 Conductive Flexible Coating
Categories:	Polymer; Adhesive
Material Notes:	Description: CHO-SHIELD® 4994 is a smooth, highly conductive flexible silver-filled polyurethane coating designed for military/aerospace airframe applications. Both coatings provide superior adhesion, excellent solvent rub and wear resistance, and are resistant against numerous operational and environmental fluids. CHO-SHIELD® 4494 can be applied to aluminum as well as non-conductive substrates and are designed to be used with primers and with external topcoat systems. CHO-SHIELD® 1091 can be used as a primer for ensuring improved performance on aluminum substrates. Information provided by Chomerics
