Description: 2984XH3E.03 New Parker Chomerics Cho-Seal EMI (Electro-Magnetic Interference) Die Cut Shield Patch Dots, Made of Nickel Plated Carbon (Ni/C) Fiber Shielding Matrix, Part Number 19-11-19907-S6305. Each bid quantity is for a Lot of One Hundred (100) EMI Patch Dots. You may bid / buy any number of lots, up to the total quantity available above. These were purchased at an industrial liquidation earlier this year, and they were in the original factory bags. We packaged them in heavy Ziplok bags for resale. They seem to be some kind of peel-and-stick dots. However, the white side does not peel off very easily - if at all. On most pieces we tested, it is *very* firmly attached, and when it does finally tear, it shreds into fibers sort of like Tyvek. The silicone is soft and pliable, but the adhesive is probably out of date (August 2005). We therefore recommend that you simply dab on a suitable liquid adhesive, and bond the EMI patch to your surface. Should be just the thing for screw holes and other small EMI leaks. The part number 19-11-19907-S6305 breaks down as follows: 19-11: Die cut product 19907: Parker internal drawing number S6305: Material Ni/C (Nickel plated carbon fiber) According to the calipers: Diameter: .379" / 9.64 mm Thickness (including white backing): .029" / 0.74 mm Thickness (including white backing): .024" / 0.61 mm According to the manufacturer: S6305 -- Good performance in moderately corrosive environments; material of choice for flange finishes needing “bite-through” for good electrical contact.
