Parker Chomerics CHO-SHIELD® 2044 Nickel-Filled Acrylic Coating for EMI Shielding
Categories: Polymer; Adhesive; Thermoset; Acrylic/Cyanoacrylate Adhesive

Material Notes: Description: CHO-SHIELD® 2044 is an electrically conductive, one-component nickel-filled acrylic coating that is especially formulated for application on plastics to provide modest EMI shielding. CHO-SHIELD® 2044 is ideal for use on electronic enclosures and assemblies. The electrical conductivity of the durable, nickel-composition paint allows for simple, standard application using conventional equipment with minimal dry-time and handling. CHO-SHIELD® 2044 is ideal for use on electronic enclosures and assemblies where abrasion resistance and coating durability are important This durable, conductive coating derives its hardness from its nickel composition and may provide limited amounts of H-field shielding. Given its relatively low conductivity as compared to other metal fillers, the nickel provides exceptional shielding for enclosures where both external RF fields must be excluded, and internal radiated emission must be attenuated.

Applications: Moderate EMI shielding, Anti-static protection, Surface grounding, Coating of ABS, PC/ABS, and many other types of plastic enclosures.
